Where is research takingus Have the scientistsmade all the major
discoveries that will be made Arewe providing adequate or inadequate funding for researchRather than answer these specific
questions let us consider the veryrecent announcement on researchinto Parkinsonrsquos disease in man Itnotes that α-synuclein (α-s) theprotein implicated in Parkinsonsdisease and other forms of neuro-degenerative diseases is releasedwhen an infection occurs in theupper GI tract (the oesophagusstomach and duodenum) inducingan immune response as part of thebodys innate immune system Theresearchers say that these findingssuggest that frequent or chronicupper GI infections couldoverwhelm the bodys capacity toclear α-s leading to diseaseAnimal studies have further shown
that microbes in the GI tract caninduce formation of toxic aggregates in the enteric nervoussystem which can then travel to thebrain The α-s can use the nervesconnecting the GI tract to thebrainstem as an escalator traffickingα-S from the gut to the brain and
chewingthecudspreading within the central nervous system Too much α-s from multiple or
chronic GI infections becomestoxic because the system that disposes of α-s is overwhelmednerves are damaged by the toxicaggregates that form and chronicinflammation ensues which couldbe the start of Parkinsonrsquos diseaseand other entities Damage occursboth within the nervous system ofthe GI tract and the brainThus the homeostasis of the gut
flora by interventions with productslike probiotics may well provide thebasis for the prevention or treatment of this disease in thefutureReturning to the dairy farm what
other substances are beingproduced by the microbiota of theGI and what are their effects in thecow or calf There could be effectson performance reproductionweaning stress and virtually everybiological function in the cowrsquosbody ndash a better understanding ofwhich could impact on theeconomics of production There is as much need today if

worldfocusAn executive summary of key international issues
The Berlin airlift in reverseThe Saudi-led blockade of Qatar has resulted in that country preparing an audacious plan toairlift thousands of dairy cows from Germany the US and Australia to address its domesticmilk shortage Based on the plan a specially configured transport plane would deliver 140German cows to air-conditioned hangars in the desert Every two or three days thereafterthere would be more planes and more cows until 4000 animals have been brought to thisarid kingdom where temperatures are regularly around 46degC This is probably the biggestairlift of livestock ever attempted An official said ldquoIf the price of Qatarrsquos independence isto airlift every single pint of milk then we will do sordquo

An lsquoAct of Godrsquo or a foreseeable problemThe recent Californian heatwave has caused an increase in cattle deaths prompting officialsto take emergency action with various areas declaring local states of emergency Demandfrom Tulare and other counties for rendering services to dispose of the animals exceededcapacity The problem was exacerbated when the local rendering facility had a mechanicalbreakdown that halted pickup and processing of dead animals Tulare county alone hasmore than half a million dairy cows It is thought that some 4000-6000 cattle died in thelast month While one has sympathy with the farmers for their losses surely someoneshould be asking whether such losses can be justified in 2017 Is this a welfare issue

New ways of looking at mastitisUsing innovative technologies scientists at the Moredun Institute Edinburgh and theUniversity of Glasgow have measured 570 proteins and 690 metabolites in milk for the firsttime in the same milk samples Among these potential biomarkers of mastitis have beenidentified These could become the basis of rapid diagnostic tests to be used with the cow togive farmers real-time information on the health status of their animals and allow fortargeted therapy Key findings from the analysis of milk during mastitis showed a largeincrease in proteins such as cathelicidin and haptoglobin that are known to have naturalantimicrobial activity

Heat stress is a common andgrowing concern in dairycows and we are now fully
aware that even at low levels it cansignificantly impact herd productionand welfareFor several years now Lallemand
Animal Nutrition has been focusingon identifying and monitoring indi-cators to assess rumen efficiencyon-farm and help producers managetheir herd for optimum productionand welfare (Fig 1)

This approach has allowed thou-sands of data to be gathered fromdifferent regions and productionsystems which reveals the impact ofheat stress beyond experimental trials in real-life conditionsData obtained from dairy farms in
multi continents under moderate tosevere stress were compiled (Fig 2)indicating that during heat stressvarious indicators were affectedl Milk fat and fatprotein ratioappears significantly lower com-pared to other seasons (milk fat379 in summer vs 395 on averageduring other seasons milk fatprotein ratio 115 in summer vs 118on average during other seasons)highlighting reduced rumen effi-ciency

l Somatic cells count in milk is sig-nificantly increased (an indicatorwhich is partially affected by poorrumen conditions but also impairedantioxidant status)Lallemandrsquos rumen audit
approach which is based on objec-tive and measurable indicators ofrumen efficiency on farm is verymuch in line with current trendsacross the industryFor example a recent study from
Penn State Extension reveals a clearcorrelation between heat stresslevel (THI) daily rumination timeand milk productionAccording to this study it is esti-
mated that for 10 points increase inTHI daily rumination could bereduced by one hour and dairy pro-duction by 27kgday Rumen efficiency is clearly
affected by heat stress and besidesthe use of heat abatement methodsLallemand recommend focusing onensuring optimal rumen function byadapting the rationThe main objective is to improve
feed efficiency to compensate forreduced feed intake while protect-ing the rumen environment fromacidosis risksl Increase the energy density ofthe diet
l Feed high quality aerobically stable and highlydigestible forage It has beenshown that heifersrsquo DMI candecrease by up to 1kgdaywith unstable corn silage l More starch or added fatcan be useful Fat is not fermented in the rumenhence does not releaseheat during digestion l High quality fibre sourcesin the diet are essential foroptimal rumen efficiencyespecially for high-producingherds receiving high starchdiets

Worldwide survey undertaken at farm level
In order to evaluate the real risks ofheat stress Lallemand AnimalNutrition has also conducted aworldwide survey at farm level
under various climate conditions byrecording in real-time THI variationswithin animalsrsquo environments Adding to external climate
recordings this allowed them tobuild a world map of heat stressrisks (Fig 4) aimed at helping pro-ducers anticipate summer problemsand be prepared even in areas notprimarily associated with hot cli-mates such as Northern and CentralEuropeIn conclusion heat stress risk is a
reality for dairy producers undervarious latitudes Heat stress represents a challeng-
ing period for the animals puttingpressure on rumen condition andefficiency and the animalrsquos antioxi-dant status as shown byLallemandrsquos recent survey Risk monitoring (for example use
of a hygro-thermometer to recordTHI in the barn) planning ahead andadapted barn and herd managementpractices are essential to optimiseproduction and help overcome heatstress challenges n

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set
there is a need to focus on anti-microbial resistance and a need to

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

dairy news from around the world
calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Where is research takingus Have the scientistsmade all the major
discoveries that will be made Arewe providing adequate or inadequate funding for researchRather than answer these specific
questions let us consider the veryrecent announcement on researchinto Parkinsonrsquos disease in man Itnotes that α-synuclein (α-s) theprotein implicated in Parkinsonsdisease and other forms of neuro-degenerative diseases is releasedwhen an infection occurs in theupper GI tract (the oesophagusstomach and duodenum) inducingan immune response as part of thebodys innate immune system Theresearchers say that these findingssuggest that frequent or chronicupper GI infections couldoverwhelm the bodys capacity toclear α-s leading to diseaseAnimal studies have further shown
that microbes in the GI tract caninduce formation of toxic aggregates in the enteric nervoussystem which can then travel to thebrain The α-s can use the nervesconnecting the GI tract to thebrainstem as an escalator traffickingα-S from the gut to the brain and
chewingthecudspreading within the central nervous system Too much α-s from multiple or
chronic GI infections becomestoxic because the system that disposes of α-s is overwhelmednerves are damaged by the toxicaggregates that form and chronicinflammation ensues which couldbe the start of Parkinsonrsquos diseaseand other entities Damage occursboth within the nervous system ofthe GI tract and the brainThus the homeostasis of the gut
flora by interventions with productslike probiotics may well provide thebasis for the prevention or treatment of this disease in thefutureReturning to the dairy farm what
other substances are beingproduced by the microbiota of theGI and what are their effects in thecow or calf There could be effectson performance reproductionweaning stress and virtually everybiological function in the cowrsquosbody ndash a better understanding ofwhich could impact on theeconomics of production There is as much need today if
not a greater need for well fundedresearch n

The Berlin airlift in reverseThe Saudi-led blockade of Qatar has resulted in that country preparing an audacious plan toairlift thousands of dairy cows from Germany the US and Australia to address its domesticmilk shortage Based on the plan a specially configured transport plane would deliver 140German cows to air-conditioned hangars in the desert Every two or three days thereafterthere would be more planes and more cows until 4000 animals have been brought to thisarid kingdom where temperatures are regularly around 46degC This is probably the biggestairlift of livestock ever attempted An official said ldquoIf the price of Qatarrsquos independence isto airlift every single pint of milk then we will do sordquo

An lsquoAct of Godrsquo or a foreseeable problemThe recent Californian heatwave has caused an increase in cattle deaths prompting officialsto take emergency action with various areas declaring local states of emergency Demandfrom Tulare and other counties for rendering services to dispose of the animals exceededcapacity The problem was exacerbated when the local rendering facility had a mechanicalbreakdown that halted pickup and processing of dead animals Tulare county alone hasmore than half a million dairy cows It is thought that some 4000-6000 cattle died in thelast month While one has sympathy with the farmers for their losses surely someoneshould be asking whether such losses can be justified in 2017 Is this a welfare issue

New ways of looking at mastitisUsing innovative technologies scientists at the Moredun Institute Edinburgh and theUniversity of Glasgow have measured 570 proteins and 690 metabolites in milk for the firsttime in the same milk samples Among these potential biomarkers of mastitis have beenidentified These could become the basis of rapid diagnostic tests to be used with the cow togive farmers real-time information on the health status of their animals and allow fortargeted therapy Key findings from the analysis of milk during mastitis showed a largeincrease in proteins such as cathelicidin and haptoglobin that are known to have naturalantimicrobial activity

Heat stress is a common andgrowing concern in dairycows and we are now fully
aware that even at low levels it cansignificantly impact herd productionand welfareFor several years now Lallemand
Animal Nutrition has been focusingon identifying and monitoring indi-cators to assess rumen efficiencyon-farm and help producers managetheir herd for optimum productionand welfare (Fig 1)
by Aureacutelien PironLallemand AnimalNutrition Francewwwlallemand
animalnutritioncom
This approach has allowed thou-sands of data to be gathered fromdifferent regions and productionsystems which reveals the impact ofheat stress beyond experimental trials in real-life conditionsData obtained from dairy farms in
multi continents under moderate tosevere stress were compiled (Fig 2)indicating that during heat stressvarious indicators were affectedl Milk fat and fatprotein ratioappears significantly lower com-pared to other seasons (milk fat379 in summer vs 395 on averageduring other seasons milk fatprotein ratio 115 in summer vs 118on average during other seasons)highlighting reduced rumen effi-ciency

l Somatic cells count in milk is sig-nificantly increased (an indicatorwhich is partially affected by poorrumen conditions but also impairedantioxidant status)Lallemandrsquos rumen audit
approach which is based on objec-tive and measurable indicators ofrumen efficiency on farm is verymuch in line with current trendsacross the industryFor example a recent study from
Penn State Extension reveals a clearcorrelation between heat stresslevel (THI) daily rumination timeand milk productionAccording to this study it is esti-
mated that for 10 points increase inTHI daily rumination could bereduced by one hour and dairy pro-duction by 27kgday Rumen efficiency is clearly
affected by heat stress and besidesthe use of heat abatement methodsLallemand recommend focusing onensuring optimal rumen function byadapting the rationThe main objective is to improve
feed efficiency to compensate forreduced feed intake while protect-ing the rumen environment fromacidosis risksl Increase the energy density ofthe diet
l Feed high quality aerobically stable and highlydigestible forage It has beenshown that heifersrsquo DMI candecrease by up to 1kgdaywith unstable corn silage l More starch or added fatcan be useful Fat is not fermented in the rumenhence does not releaseheat during digestion l High quality fibre sourcesin the diet are essential foroptimal rumen efficiencyespecially for high-producingherds receiving high starchdiets

Worldwide survey undertaken at farm level
In order to evaluate the real risks ofheat stress Lallemand AnimalNutrition has also conducted aworldwide survey at farm level
under various climate conditions byrecording in real-time THI variationswithin animalsrsquo environments Adding to external climate
recordings this allowed them tobuild a world map of heat stressrisks (Fig 4) aimed at helping pro-ducers anticipate summer problemsand be prepared even in areas notprimarily associated with hot cli-mates such as Northern and CentralEuropeIn conclusion heat stress risk is a
reality for dairy producers undervarious latitudes Heat stress represents a challeng-
ing period for the animals puttingpressure on rumen condition andefficiency and the animalrsquos antioxi-dant status as shown byLallemandrsquos recent survey Risk monitoring (for example use
of a hygro-thermometer to recordTHI in the barn) planning ahead andadapted barn and herd managementpractices are essential to optimiseproduction and help overcome heatstress challenges n

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability

Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

dairy news from around the world
calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

aware that even at low levels it cansignificantly impact herd productionand welfareFor several years now Lallemand
Animal Nutrition has been focusingon identifying and monitoring indi-cators to assess rumen efficiencyon-farm and help producers managetheir herd for optimum productionand welfare (Fig 1)

This approach has allowed thou-sands of data to be gathered fromdifferent regions and productionsystems which reveals the impact ofheat stress beyond experimental trials in real-life conditionsData obtained from dairy farms in
multi continents under moderate tosevere stress were compiled (Fig 2)indicating that during heat stressvarious indicators were affectedl Milk fat and fatprotein ratioappears significantly lower com-pared to other seasons (milk fat379 in summer vs 395 on averageduring other seasons milk fatprotein ratio 115 in summer vs 118on average during other seasons)highlighting reduced rumen effi-ciency

approach which is based on objec-tive and measurable indicators ofrumen efficiency on farm is verymuch in line with current trendsacross the industryFor example a recent study from
Penn State Extension reveals a clearcorrelation between heat stresslevel (THI) daily rumination timeand milk productionAccording to this study it is esti-
mated that for 10 points increase inTHI daily rumination could bereduced by one hour and dairy pro-duction by 27kgday Rumen efficiency is clearly
affected by heat stress and besidesthe use of heat abatement methodsLallemand recommend focusing onensuring optimal rumen function byadapting the rationThe main objective is to improve
feed efficiency to compensate forreduced feed intake while protect-ing the rumen environment fromacidosis risksl Increase the energy density ofthe diet

Worldwide survey undertaken at farm level
In order to evaluate the real risks ofheat stress Lallemand AnimalNutrition has also conducted aworldwide survey at farm level
under various climate conditions byrecording in real-time THI variationswithin animalsrsquo environments Adding to external climate
recordings this allowed them tobuild a world map of heat stressrisks (Fig 4) aimed at helping pro-ducers anticipate summer problemsand be prepared even in areas notprimarily associated with hot cli-mates such as Northern and CentralEuropeIn conclusion heat stress risk is a
reality for dairy producers undervarious latitudes Heat stress represents a challeng-
ing period for the animals puttingpressure on rumen condition andefficiency and the animalrsquos antioxi-dant status as shown byLallemandrsquos recent survey Risk monitoring (for example use
of a hygro-thermometer to recordTHI in the barn) planning ahead andadapted barn and herd managementpractices are essential to optimiseproduction and help overcome heatstress challenges n

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

As an integral part of making consistently better silage profes-sional farmers return to Ecosylsilage additives year after year
ecosylcom
Not only has the specially-selected MTD1 strain ofLactobacillus plantarum bac-teria contained in Ecosylbeen shown to deliver fastersilage fermentation but alsohigher dry matter intakesand improved digestibility
And that is just the start Ithas also been proven todeliver the most importantbenefit of all improved milkyield Across a range of crops
and dry matters milk yield wasraised by an average of an extra 12litres of milk per cow per day fol-lowing treatment with Lactobacillusplantarum MTD1
Moreover this was not researchby Ecosylrsquos manufacturer Volac
This was found across 15 indepen-dent dairy trials
There are now Ecosyl addi-tives available for conven-tional and higher dry mattersilages baled and clampsilages and for grass maizewholecrop cereals andlegumes No wonder thenthat Ecosyl has been trustedto help farmers take greatercontrol of silage-making for
more than 30 years

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Cassava chips (CC) have a strong potential as an energy source for ruminants in tropical areas How-ever it is a source of quick ruminal- fermentable energy therefore itleaves risk for subclinical acidosisMalate has shown to be effectivein preventing acidosis as it increasesruminal pH and decreases lactateKhampa et al performed two ex-periments to evaluate the benefitsof malate in CC diets The first experiment was carriedout with dairy steers receiving ahigh CC (70) concentrate diet withvarious levels of malic acid salt andad libitum urea as well as treatedrice straw roughageMalate showed changes on drymatter intake increased and sta-bilised ruminal pH increased ammo-nia-nitrogen blood urea nitrogenand total volatile fatty acids It also changed the proportion of
fatty acids in favour of propionateresulting in more available energy The second experiment was car-ried out with lactating dairy cowsreceiving high CC concentrate (70and 75) with various levels of ureaand malate Malate improved the digestibility of organic matter crudeprotein and fibre In addition higher doses of malateresulted in lesser ruminal lactic acidand faecal nitrogen Microbial nitrogen supply also increased along with malate doseFinally the study showed thatmalate improved rumen ecology

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Heat stress is a common andgrowing concern in dairycows and we are now fully
aware that even at low levels it cansignificantly impact herd productionand welfareFor several years now Lallemand
Animal Nutrition has been focusingon identifying and monitoring indi-cators to assess rumen efficiencyon-farm and help producers managetheir herd for optimum productionand welfare (Fig 1)
by Aureacutelien PironLallemand AnimalNutrition Francewwwlallemand
animalnutritioncom
This approach has allowed thou-sands of data to be gathered fromdifferent regions and productionsystems which reveals the impact ofheat stress beyond experimental trials in real-life conditionsData obtained from dairy farms in
multi continents under moderate tosevere stress were compiled (Fig 2)indicating that during heat stressvarious indicators were affectedl Milk fat and fatprotein ratioappears significantly lower com-pared to other seasons (milk fat379 in summer vs 395 on averageduring other seasons milk fatprotein ratio 115 in summer vs 118on average during other seasons)highlighting reduced rumen effi-ciency
l The percentage ofcows in good bodycondition islowerl The percentage ofclean cows isreducedl Manurescreeningshowsreduceddigestionefficiency theoccurrence ofmanure withmore than oneundigested butprocessed grain isincreased
l Somatic cells count in milk is sig-nificantly increased (an indicatorwhich is partially affected by poorrumen conditions but also impairedantioxidant status)Lallemandrsquos rumen audit
approach which is based on objec-tive and measurable indicators ofrumen efficiency on farm is verymuch in line with current trendsacross the industryFor example a recent study from
Penn State Extension reveals a clearcorrelation between heat stresslevel (THI) daily rumination timeand milk productionAccording to this study it is esti-
mated that for 10 points increase inTHI daily rumination could bereduced by one hour and dairy pro-duction by 27kgday Rumen efficiency is clearly
affected by heat stress and besidesthe use of heat abatement methodsLallemand recommend focusing onensuring optimal rumen function byadapting the rationThe main objective is to improve
feed efficiency to compensate forreduced feed intake while protect-ing the rumen environment fromacidosis risksl Increase the energy density ofthe diet
l Feed high quality aerobically stable and highlydigestible forage It has beenshown that heifersrsquo DMI candecrease by up to 1kgdaywith unstable corn silage l More starch or added fatcan be useful Fat is not fermented in the rumenhence does not releaseheat during digestion l High quality fibre sourcesin the diet are essential foroptimal rumen efficiencyespecially for high-producingherds receiving high starchdiets

Worldwide survey undertaken at farm level
In order to evaluate the real risks ofheat stress Lallemand AnimalNutrition has also conducted aworldwide survey at farm level
under various climate conditions byrecording in real-time THI variationswithin animalsrsquo environments Adding to external climate
recordings this allowed them tobuild a world map of heat stressrisks (Fig 4) aimed at helping pro-ducers anticipate summer problemsand be prepared even in areas notprimarily associated with hot cli-mates such as Northern and CentralEuropeIn conclusion heat stress risk is a
reality for dairy producers undervarious latitudes Heat stress represents a challeng-
ing period for the animals puttingpressure on rumen condition andefficiency and the animalrsquos antioxi-dant status as shown byLallemandrsquos recent survey Risk monitoring (for example use
of a hygro-thermometer to recordTHI in the barn) planning ahead andadapted barn and herd managementpractices are essential to optimiseproduction and help overcome heatstress challenges n

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are

As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and

gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay
New data evaluating the effect ofrake-type on ash content of alfalfahay were presented at the lastMinnesota Nutrition Conferenceis study was conducted by aresearcher from University ofMinnesota on first cutting alfalfahay fields located in MinnesotaPennsylvania and Wisconsin Twoswaths of mowed hay wereconsolidated with a wheel rakeside-delivery rake rotary rake or amerger Hay merger consistentlyproduced bales having the leastamount of ash (114 98 and 92ash as percent of dry matter inMinnesota Pennsylvania andWisconsin respectively) while thewheel rake produced bales with thegreatest amount of ash (146 11195 ash in MN PA and WI)
Since ash content of alfalfa greaterthan 8 indicates hay has beencontaminated with soil theseresults suggest farmers looking toreduce ash content of hay shouldconsider using a hay merger whencombining swaths

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels

Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today

physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Silage is one of the most cost-effectivefeeds available for dairy cows Butthere is room for improving the way it
is made according to survey results fromVolac the makers of Ecosyl silage additives
by Jackie BradleyRegional Product Manager
Volac International Ltdwwwvolaccom
Silage is a highly cost-effective feed Sofor dairy farms looking to minimise costsand maximise output producing the bestpossible silage makes a lot of senseMoreover making silage is nothing new
So you would think by now everyoneinvolved in silage-making would know howto make top-quality materialBut is this the case Results suggest not In
our most recent survey conducted amongmore than 100 UK dairy farmers a massive78 thought they could make better grasssilage Most producers simply did not feelin full control of the process Just 19 of respondents said they felt
completely in control of how well theirgrass silage turns out once they had sealedthe clamp ndash with 85 in a further questionsaying they would like to feel more incontrol When we dug deeper we foundsome concerning gaps in the silage-makingmethods being used
Efficient fermentation
Although 90 of respondents said theyrolled continuously when consolidatingsilage in the clamp ndash which is important forsqueezing out air to achieve an efficient
fermentation and minimise aerobic spoilagendash only 38 said they normally filled theclamp in layers no more than 15cm thickThis is significant because 15cm is themaximum forage depth that can beconsolidated effectively Also only 17 said they achieved a grass
dry matter density of 250kg per cubic metewhen consolidating which is the optimumfor grass at 30 dry matterWorryingly the process of fermentation
seemed to be poorly understood Only halfof respondents realised that crop drymatter at harvest has a big impact on grasssilage fermentation Science tells us that during fermentation
beneficial bacteria convert crop sugars intoacids which pickle the forage Yet only afifth (21) of respondents recognisedfermentation was a process whereby forageis pickled in acid
Some 28 of respondents also thought agood silage fermentation was largelydependent on the bacteria naturallypresent on grass It is perhaps not surprising therefore that
many producers did not feel completely incontrol of how well their grass silageturned out
Beneficial bacteria
While there will almost certainly be somebeneficial bacteria naturally present ongrass if you rely solely on these you do notknow if they are present in sufficientnumbers Nor indeed if they are the besttype to carry out a fast and efficientfermentation needed for optimum nutrientpreservation

There may also be unwanted microbespresent ndash such as enterobacteria clostridiayeasts and moulds ndash which can result inpoor fermentation spoilage and wastednutrientsBy comparison we know that a qualitysilage additive can apply as many as onemillion beneficial bacteria per gram offorage treated when used correctly More to the point these bacteria willhave been specially selected to be highlyefficient at fermentation And the follow-on benefits of adding these beneficialbacteria can be substantial They include reduced dry matter lossesimproved silage ME and improveddigestibility Most importantly we haveseen clear improvements in milk yieldAcross a range of forages milk yield wasincreased by an average of an extra12lcowday in trials using Lactobacillusplantarum MTD1 ndash the bacterium invarious Ecosyl products If anything provides a compelling reasonfor including an additive in silage-makingimproved milk yield should A provenadditive represents a small investment for alot of additional peace-of-mind
Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels

When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

growth of epithelial cells that form the toplayer of the skin The originally inorganicmolecules Cu2+ and Zn2+ are covered(chelated) with an organic layer thatprovides unique propertiesIn a recent randomised clinical trial on 231
severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for

seropositive caprine arthritisencephalitis virus and subclinicalmastitis was found in 523 of thegoats Both findings were present in 30
Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields

The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay
New data evaluating the effect ofrake-type on ash content of alfalfahay were presented at the lastMinnesota Nutrition Conferenceis study was conducted by aresearcher from University ofMinnesota on first cutting alfalfahay fields located in MinnesotaPennsylvania and Wisconsin Twoswaths of mowed hay wereconsolidated with a wheel rakeside-delivery rake rotary rake or amerger Hay merger consistentlyproduced bales having the leastamount of ash (114 98 and 92ash as percent of dry matter inMinnesota Pennsylvania andWisconsin respectively) while thewheel rake produced bales with thegreatest amount of ash (146 11195 ash in MN PA and WI)
Since ash content of alfalfa greaterthan 8 indicates hay has beencontaminated with soil theseresults suggest farmers looking toreduce ash content of hay shouldconsider using a hay merger whencombining swaths

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Preserving maize
However it is not just when making grasssilage that there seems to be room forimprovement An earlier survey weconducted among 70 UK dairy farmerssuggested similar results for maizeWhile 71 of respondents ratedpreventing aerobic spoilage as the biggestchallenge faced when preserving maizesilage not all respondents were fullyutilising all the available preventativemethodsOnly 60 said they used goodconsolidation And while three quarters(75) said they used tight sealing only athird (32) used fast filling of the clamp orfilling in thin layers (35) Yet we know thatall these steps are vital for minimising air inthe clamp and therefore minimisingspoilage organisms
Similarly at feedout only around half(54) of respondents were using a blockcutter or shear grab to keep the face tidywith fewer than a third (31) moving theface back quickly Both of which are key forminimising air ingressEqually only around half of surveyrespondents (54) included an additive tocounteract maize aerobic spoilage One of the reasons that some of thesecrucial steps were not being used whichwas hinted at by the survey was that not allfarmers fully appreciated the damage thataerobic spoilage can causeRoughly a third of respondents did notrecognise it as causing losses in feed qualityor risk of mycotoxins Also only around ahalf of respondents (54) identified thataerobic spoilage leads to lost dry mattertonnageIn reality we know that dry matter lossesin maize can occur both as a result of poorfermentation and aerobic spoilage ndash withthe greatest losses likely to come from thelatter So it is important to target bothcauses It is perfectly possible to do thisusing an additive combining efficient
fermentation bacteria of Lactobacillusplantarum MTD1 with another beneficialbacterium L buchneri PJB1 that inhibitsyeasts and moulds ndash for example with theproduct Ecocool which is available incertain parts of the world
Conclusion
Ultimately with the importance ofmaximising milk from home-producedforage understanding the scale of losses infeed value and dry matter that can occur insilage ndash whether maize grass or any othercrop ndash is crucial But what is also importantis to understand what causes them ndashwhether poor fermentation or aerobicspoilage or a combination of bothWithout this information milk producersdo not know how much focus to put onpreventing them or the silage managementtechniques and types of additives thatshould be used Using good silagemanagement plus a proven additive andpaying attention to the details will putfarmers in greater control n

Experiences in China
Experience gained last season has pointed to additive use becoming an integral part ofsilage-making on farms in China striving for maximum nutrients from forage It is anapproach that other parts of the world would benefit from
ldquoAs the people of China look to consume more dairy products there is clearly a need forefficient milk productionrdquo Derek Nelson Ecosyl global product manager toldInternational Dairy Topics
ldquoHaving presented research findings on Ecosyl ndash including results on reduced dry matterlosses improved silage quality and animal performance ndash we saw the additive beingroutinely adopted to preserve maize silage across multiple Chinese farms last seasonThese farms formed part of a leading Chinese dairy business
ldquoMaize silage was made at 30-35 dry matter So the preservation objectives were verysimilar to those in the West It was also fed in a total mixed ration along with grassalfalfa and concentrates to year-round-housed cows
ldquoWith the quest for efficient milk production this is a really good example of leavingnothing to chance when it comes to getting the best out of silagerdquo Derek concludes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are

As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and

gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system

System building blocks

l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and

The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Due to their high feed intakes andhigh concentrate forage ratios indiets high producing dairy cows are
at risk for negative impacts of themycotoxin deoxynivalenol (DON) on milkquality and component yields
by Gwendolyn Jones Anco AnimalNutrition Competence
wwwanconet
The extent of the negative response canbe managed by nutritional means throughthe use of certain phytogenic substancesfor more consistent milk component yields
Variation in milk component yields
Increasingly the levels of protein and fat inmilk are being recognised as majordeterminants of milk price As a result milkcomponent levels are important factors inherd management and directly impact farmincomeProduction of milk fat and protein canvary a lot from one herd to another USstudies showed that herd average milkprotein ranged from 157-466 with anaverage of 305 Milk fat ranged from 177-598 with an average of 376 Thisindicates that many herds are producingcomponents below average for their marketand their breed which presents anopportunity to improve componentproduction and income from milk sales
Principally the yield and the content ofmilk fat are influenced by the digestion offeed in the rumen Provided the rationcontains adequate levels of digestible fibreand the cow efficiently digests that fibrethe acids produced in the rumen willsupport efficient milk fat synthesis bringingresponses in both fat yield and contentBut in many cows the rumen may be lessefficient than we believe DON the mostprevalent mycotoxin in animal feedstuffsglobally has been shown to have a negativeimpact on rumen efficiency Scientificstudies reported that DON negativelyimpacted certain aspects of rumenfermentative capacity especially reducedacetate and propionate production
Impact of DON on milk parameters
Ruminants are regarded as quite resistant toFusarium toxins such as deoxynivalenol(DON) because of the detoxifying potentialof rumen microbes However thedetoxification capacity of rumen microbesdepends on a functional rumen Highproducing dairy cows with high feed intakesand high levels of concentrates in theirration are more susceptible to the negativeeffects of DONThis is because on the one hand itincreases the passage rate in the rumengiving the microbes less time to degrademycotoxins and on the other hand reducesrumen pH which has a negative effect onDON degradation in the rumen The data inFig 1 shows that DON is degraded at aslower pace in the rumen with high starchlevels in the diet compared to diets withhigh levels of celluloseScientific literature reveals that unlikeaflatoxin there is very little carry-over fromDON in dairy rations into milk HoweverDON in rations for dairy cows has beenshown to decrease milk fat and increasesomatic cell counts (SCC) DON is known toincrease oxidative stress which in dairycows has been related to oxidativemammary tissue damage and increased SCC There is further evidence that DONaffects rumen fermentation and microbial

protein yield which can again affect feedefficiency and milk component yields
Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home
Spinning manure intogold managementseparation systems

bull Impact of reducing the number of heavyloads on the roadbull Ability to maintain nutrient distributionacross farm ground by cost-effectivelyspreading nutrients on fields further awayl Reduced time to agitate manure storageand homogenise nutrientsl Removal of large particles for nozzle ormicro-drip irrigationl Manure-to-water systems that reducethe volume to haul or storel Nutrient partitioning to match cropneedsbull Timing of nutrient application (have aproduct available to land apply)bull Split nutrient streams into crops individualneeds
An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions
providers and farmers however do have theopportunity to partner up in spinningmanure into gold while benefitting thelivestock operation the neighbours and theenvironment n

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-

The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Managing the response to DON
Traditionally feed additives have beendeveloped to attack mycotoxins in theanimalrsquos digestive tract directly tocounteract harmful effects frommycotoxins in the animal However bothmycotoxin binders and mycotoxindeactivators have their limitationsIt is well known that adsorption is not an
effective strategy for most mycotoxinsOnly certain bentonites work well with
aflatoxins and some yeast cell wallcomponents have been proven to bindzearalenone based on specific structuralfits For other types of mycotoxinsparticularly DON binding strategies do notwork effectivelyBiotransformation of mycotoxins is
another strategy that directly attacksmycotoxins to transform their structureinto non-toxic metabolites Again thisstrategy is very specific to certain targetmycotoxins On top of that it takes time tocomplete the biotransformation ofmycotoxins and time to do so in thedigestive tract is limited particularly whenfeed passage rate is high The question ishow does the animal deal with themycotoxins left untouched by the highlyspecific feed solutions mentioned above A third and more cost effective strategy
to counteract mycotoxins focuses ondisarming mycotoxins by supporting theanimalrsquos resistance to the harmful effects ofmycotoxins This strategy empowers animals to adapt
to difficult mycotoxins such as DON andreduces the extent of the stress reactionsgenerally seen in response to them Thereare ways to increase the resistance in cowsto DON by nutritional means (Table 1) Forinstance adding plant extracts with highanti-oxidative capacity to the diet thateither scavenge Reactive Oxygen Species(ROS) or upregulate and protectendogenous antioxidant defences haveshown to enhance ROS detoxifyingcapacity in animals thus reducing oxidativestress in response to DON Several bioactive substances derived from
herbs and spices have also been shown tohave high anti-inflammatory properties Others are known for their ability to help
maintain efficient rumen fermentation andhigh feed intakes So there is scope for nutritional means to
optimise the response of cows tomycotoxins such as DON in favour ofconsistent milk component yields with anoptimal combination of plant extractssuited to the cow and the challengespresented by DON n

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions
providers and farmers however do have theopportunity to partner up in spinningmanure into gold while benefitting thelivestock operation the neighbours and theenvironment n

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability

Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water
intake reduced milk yield normalbody temperature and normal feedintake should be suspected of beinginfected with Schistosoma nasale
NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

levels of protein and energy arerequired to ensure normal uterineinvolution and start to ovarianactivity postpartum
Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling
Mastitis and arthritis in Alpine goatsIn this Croatian study (Vet Arhiv 87121-128) the prevalence and aetiology of subclinical mastitis wasevaluated in goats that wereseropositive for caprine arthritisencephalitis virus The connection to the occurrence

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Somatic cell count (SCC) is the totalnumber of cells per millilitre of milkand is one of the main indicators of
milk quality in dairy cows Somatic cells aremade of 2 mammary gland cells andaround 98 white blood cells ndash leucocytesthat are immune cells produced by thecowrsquos immune system
By Dr Valentin NenovGlobal Ruminant ManagerPhileo Lesaffre Animal Carewwwphileo-lesaffrecom
As SCC are immune cells the numberfound in the milk increases as a response toan immune challenge in the udder Thischallenge is usually caused by pathogensand leads to inflammation
The most important factor affecting theSCC for an individual quarter andeventually at herd level is the mammarygland infection known as mastitis Otherfactors involved in raising SCC are minorand insignificant compared to mastitis sothis allows us to use SCC as an indicator forsubclinical mastitis
While mastitis is the most common andexpensive disease in dairy farms SCC givesus the opportunity to monitor subclinicalcases on an individual and herd level usingvarious SCC tests such as the CMT(California Mastitis Test) or digital on-farmcounters Mastitis is considered the greatestthreat to the dairy industry from threeperspectives economic hygiene and legal(EU Directive 4692 modified by Directive7194)
Mechanism
Mastitis is caused by a variety of micro-organisms the majority of which arebacteria that enter the mammary glandthrough the teat canal Mastitis itself isinflammation of the mammary gland inresponse to the infection caused by thesepathogens and in rare cases to chemical ormetabolic factors
Appropriate immune function is essentialfor host defence against intramammaryinfections The first and most common line
of defence is the innate immune systemwhich triggers a proinflammatory responseIt is a known fact that the mammary glandimmune system is compromised duringdrying-off and around calving the twoperiods representing the highest risk ofmammary infection
The mammary gland has a number ofdefence mechanisms including differentimmune cells that react immediately to apathogen challenge and form the first lineof defence Despite these mechanisms ithas been suggested that the mammarygland is immunocompromised whencompared to other parts of the body
To stop infection additional immune cellsmigrate to the mammary gland raising theSCC and reducing milk secretion due to theincreased inflammation
The first immune cells that are recruitedand migrate into the mammary gland arethe neutrophils (PMNs) which form animportant line of defence
The primary function of PMNs is to engulfphagocytise and destroy foreign materialincluding invading bacteria In a perfectsituation the action of these neutrophilswould eliminate the bacteria causing theinfection When the immune system isfunctioning properly the problem shouldbe rapidly resolved with a short andtransient increase in SCC
However this is not the case for mostcows especially around calving and drying-off and during periods of stress when theimmune system is suppressed
In these cases the number of matureneutrophils is limited and insufficient but
the bone marrow continues to producelarge numbers of immature neutrophils thatare mobilised to the area of inflammation
Several important functions are not fullydeveloped in immature neutrophilsincluding those related to phagocytosisintracellular killing and chemotaxis
These immature neutrophils make upmost of the SCC during clinical orsubclinical mastitis being recruited into themammary gland in increasing numbers butthey are unable to reduce the pathogenload
The solution is to reduce the level ofbacteria using antibiotics that directly killthem or to stimulate the immune systemto increase the proportion of matureneutrophils capable of destroying thepathogens
Economic impact of somatic cellcount on milk production
Somatic cells are not only a scientificconcept but they are also of great practicalimportance to farmers High SCCs arerelated to a milk premium or penalty andalso directly affect milk production SCCrises in response to mammary glandinfection causing inflammation andreducing the ability of the mammary glandtissue to produce milk
The symptoms of acute mastitis areclearly visible and the reduction in milkproduction is well defined Financial lossesarising from a case of mastitis are related to

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm

System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

growth of epithelial cells that form the toplayer of the skin The originally inorganicmolecules Cu2+ and Zn2+ are covered(chelated) with an organic layer thatprovides unique propertiesIn a recent randomised clinical trial on 231
severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay
New data evaluating the effect ofrake-type on ash content of alfalfahay were presented at the lastMinnesota Nutrition Conferenceis study was conducted by aresearcher from University ofMinnesota on first cutting alfalfahay fields located in MinnesotaPennsylvania and Wisconsin Twoswaths of mowed hay wereconsolidated with a wheel rakeside-delivery rake rotary rake or amerger Hay merger consistentlyproduced bales having the leastamount of ash (114 98 and 92ash as percent of dry matter inMinnesota Pennsylvania andWisconsin respectively) while thewheel rake produced bales with thegreatest amount of ash (146 11195 ash in MN PA and WI)
Since ash content of alfalfa greaterthan 8 indicates hay has beencontaminated with soil theseresults suggest farmers looking toreduce ash content of hay shouldconsider using a hay merger whencombining swaths

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

treatment discarded milk and hidden costssuch as reduced milk yield during theremainder of the lactation period and therelated culling The earlier the mastitisoccurs in the lactation period the higherthe costs A case study in five large dairy herds inNew York State found that an average caseof clinical mastitis had an estimated cost of$179 This was composed of $115 for milk yieldlosses $14 for increased mortality and $50for treatment-associated costs The estimated cost of clinical mastitis washighly dependent on cow traits it washighest ($403) in cows with high expectedfuture net returns (young high-yieldingcows) and lowest ($3) in cows that wererecommended to be culled for reasonsother than mastitisThe cost of clinical mastitis in a cow inthe first 30 days of lactation was estimatedat $444 These are obvious clinical cases ofmastitis that require treatment and specialcare but most mastitis is subclinical andgoes undetected by the farmer and is notregarded as a potential economic loss We can use the SCC as an indicator toevaluate losses from subclinical mastitisMost farmers will consider the SCC in asimilar way to fat and protein as just ameasurement for milk premium or penalty
Many studies show that changes in SCC arerelated to economic losses that go farbeyond the milk premium An increase in SCC has several effects
l Reduces milk production over the entirelactationl Increases the risk of clinical mastitisl Increases culling rate due tounacceptably high SCC and mastitisAn increase in bulk milk SCC to over100000 affects milk production (Table 1)Similar numbers were produced by meta-analysis of a large number of referencestudies from the USA Canada UKGermany and many other Europeancountries According to this meta-analysis whenbulk milk SCC is above 100000 the farmloses about 3 of its milk production As well as reducing milk production ahigh SCC increases the risk of clinicalmastitis and related culling rates
l Reducing SCCIf we take into account the reduced milkproduction and increase in cases of clinicalmastitis and culling rates we can estimatethat a farm with 100 cows and average yieldof 8000kgcowyear could actually gainaround euro4000 per year by reducing SCC byfrom 200000 to 100000 depending onmilk price Investment in reducing SCC can increasedairy farm profitability Several methods
can be considered when building a strategyfor SCC reduction
l CullingIt is recommended that cows with very highSCCs for a prolonged length of time areculled as they are more prone to clinicalmastitis and fertility problems Howeverculling should be carried out according toan established breeding program and incollaboration with a vet
Prevention throughmedication
The most common method used to fightsubclinical mastitis and prevent clinicalcases is the use of intramammaryantibiotics Most cows on commercial dairyfarms will be treated with intramammarydry cow antibiotics before drying off This issupposed to prevent bacterial infectionsduring the dry period
Prevention through hygiene andmanagement
Improving hygiene to reduce mastitis iscrucial for udder health and ultimately forsuccessful dairy farming It is simply keepingthe udder clean and free of the pathogenicbacteria that cause mastitis Major teatcontamination can be avoided byeliminating mud and preventing theformation of puddles in the cowsrsquo walkingareas Keeping bedding dry and clean
Milking practices
Cleaning and disinfecting the milkingmachines and the udder before and aftermilking Correct vacuum regulation Highervacuum levels cause the teat canal toremain open for longer after milkingallowing pathogens to enter the udder Increasing the number of milkings per daymay also help reduce SCC as the bacteriaare expelled from the udder more often
Dry cow management
The risk of intramammary infection isgreatest during the early and late dryperiod In the early dry period pathogensremain from the lactation period but theyare no longer flushed out by daily milking Most cases of mastitis in fresh cows arecaused by bacteria remaining from the dryperiod Cows should be dried off when individualSCCs are below 200000 to reducepathogen levels during the dry periodCows with higher SCCs should be treatedbefore drying off If cows are not properlydried off mastitis can occur during the dryperiod tooDry cows should be monitored for signs

of mastitis such as redness and swelling ofthe udder and treated accordingly
Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

Automation of feeding plays a cen-tral role for farmers in increasingbusiness profitability as up to 70of the operational costs on a dairyfarm is related to feeding
geacom
The automated feeding philoso-phy of GEA is completed by theirnew GM bunker series whichincludes the familiar GM17 as wellas the new GM23 and GM20 hori-zontal feed bunkers for loose mate-rial
The feeding bunkers support thefarmerrsquos feeding strategy by ensur-ing high quality conservation and
accurate weighing of the feedThanks to a unique stainless steelbottom chain the feed is gentlymoved towards a number of rollerswhich in turn accurately distributesit to a conveyor belt mixer or feedwagon
The GEA GM bunker series is acomplete concept that enables thehandling of several types of rawfeed materials It also comes in dif-ferent volumes The GM bunkerseries is made of stainless steel for along lifespan and the design reducesthe accumulation of feed in criticalparts Service and regular mainte-nance is simple thanks to easyaccess to the required areas

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Nutritional management
Nutrition is involved in maintainingimmunity and insufficient energy and otherdeficiencies affect the cowrsquos resistanceNutrient deficiency may lead to negativeenergy balance and immunosuppressionWell-balanced diets with sufficientnutrients may help support a fullyfunctional immune system helping reduceSCC When supplied in the diet certainprobiotics and prebiotics have also provedbeneficial to the immune systemsupporting a satisfactory immune responseand contributing to SCC reduction Someimmune modulation has been documentedwith some strains of live yeast such asSaccharomyces cerevisiae Sc 47 (Actisaf)and selected yeast parietal fractions suchas Safmannan
How does probiotic yeast helpreduce SCC
The small intestine is the largest immuneorgan in the body and is rich in immunecells (macrophages and dendritic cells)These cells are in constant contact withdifferent pathogens and native flora in theintestinal lumen and their role is to triggerthe immune system by providinginformationWhen the immune system is prepared for
a pathogen challenge it reacts quickly andefficiently with less inflammation andenergy expenditure When the diet issupplemented with Actisaf yeast probioticand Safmannan they can interact with thebeneficial microflora in the intestinepromoting their growth and strengtheningthe gutrsquos resistance to pathogens The specific structure of the yeast
fraction also enables it to lsquocommunicatersquodirectly with the immune cells locatedthroughout the intestinal mucosa and helptrigger a positive and satisfactory immuneresponse This interaction increases thecapacity of the immune system to recruit
mature and differentiated neutrophilswhich can identify and reduce pathogensfaster and with less inflammation
Australian trial
With its unique metabolic effect Actisafcan support the beneficial microflora in thesmall intestine and enhance the immuneresponse helping to maintain a low SCCA trial was carried out on an Australian
dairy farm with 800 lactating Holsteincows 88 cows in early lactation were splitin two groups a Treatment group whichwas fed a basal diet supplemented with5gcd Actisaf and a Control group whichwas fed the basal diet only Milk yield andmilk fat were seen to increase significantlyand SCC reduced significantly by more than44 (Fig 1)
Satisfactory immune response
To complement the effects of Actisaf yeastprobiotic the selected yeast parietalfraction Safmannan which has a specificsurface structure thanks to its controlledproduction process can interact withimmune cells helping to trigger a strongand satisfactory immune responseIn an in vitro study on LPS-challenged
macrophages Safmannan demonstrated astrong and swift immunomodulatory effectmeasured by the levels of TNF-a producedby the macrophages (Fig 2)
In comparison non-purified dead yeastwhich has similar components but adifferent surface structure does not triggerany immune response The immune response from Safmannan is
stronger when faced by a challenge like LPS(lipopolysaccharide an endotoxin producedby Gram-negative bacteria such as E coli)stimulating a more appropriate reactionfrom the immune system and reducinginflammation
Dutch trial
When Actisaf is combined with Safmannanat 8gcd it reduces SCC even more EightDutch dairy farms that had been feedingActisaf for a long time supplemented theircows with an additional 8gcd Safmannanfor a trial period Three milk samples weretaken from each farm before Safmannansupplementation and three samples afterThe SCC decreased over the trial periodfrom an average of 280000 per farm tobelow 200000 (Fig 3)
Conclusion
The SCC is predominantly made up ofimmune cells which are present in theudder as a response to infection High SCClevels are related to subclinical mammarygland infections ndash mastitis Reducing theSCC in bulk milk has been shown toincrease dairy farm profits significantly andis very often the difference betweenprofitable farms and farms which make aloss There are many ways to work towards
reducing a herdrsquos SCC including usingpharmaceuticals changing management andhygiene practices and using modernprobiotics and prebiotics to prime theimmune system No single method issufficient in isolation and a good programthat combines different practices can helpreduce SCC and optimise milk performance Whatever program is set up on the farm
to reduce SCC adding probiotics to thediet that modulate the immune responseincreases the likelihood of success n

As an integral part of making consistently better silage profes-sional farmers return to Ecosylsilage additives year after year
ecosylcom
Not only has the specially-selected MTD1 strain ofLactobacillus plantarum bac-teria contained in Ecosylbeen shown to deliver fastersilage fermentation but alsohigher dry matter intakesand improved digestibility
And that is just the start Ithas also been proven todeliver the most importantbenefit of all improved milkyield Across a range of crops
and dry matters milk yield wasraised by an average of an extra 12litres of milk per cow per day fol-lowing treatment with Lactobacillusplantarum MTD1
Moreover this was not researchby Ecosylrsquos manufacturer Volac
This was found across 15 indepen-dent dairy trials
There are now Ecosyl addi-tives available for conven-tional and higher dry mattersilages baled and clampsilages and for grass maizewholecrop cereals andlegumes No wonder thenthat Ecosyl has been trustedto help farmers take greatercontrol of silage-making for
more than 30 years

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions
providers and farmers however do have theopportunity to partner up in spinningmanure into gold while benefitting thelivestock operation the neighbours and theenvironment n

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

dairy news from around the world
calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management
GEA Farm Technologies Inc USA wwwgeacom
How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home
Spinning manure intogold managementseparation systems

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay
New data evaluating the effect ofrake-type on ash content of alfalfahay were presented at the lastMinnesota Nutrition Conferenceis study was conducted by aresearcher from University ofMinnesota on first cutting alfalfahay fields located in MinnesotaPennsylvania and Wisconsin Twoswaths of mowed hay wereconsolidated with a wheel rakeside-delivery rake rotary rake or amerger Hay merger consistentlyproduced bales having the leastamount of ash (114 98 and 92ash as percent of dry matter inMinnesota Pennsylvania andWisconsin respectively) while thewheel rake produced bales with thegreatest amount of ash (146 11195 ash in MN PA and WI)
Since ash content of alfalfa greaterthan 8 indicates hay has beencontaminated with soil theseresults suggest farmers looking toreduce ash content of hay shouldconsider using a hay merger whencombining swaths

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability

Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Omission teat preparationThis Irish study (Irish J of Aric andFood Res 55 169-175) was under-taken to investigate the effect ofomitting teat preparation prior tomilking on the bacterial levels in themilk immediately after milking andafter a period of storage (0 24 48or 72 hours at 4degC)The total bacterial count of the
milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis
asynchrony in the occurrence oflactation and dry matter intake Inthe tropics this scenario is exacer-bated due to poor quality and dietshortagesThis Colombian study (Arquiv
Brasil de Med Vet e Zootec 69 1-9)looked at the nutrition andbehaviour of cross bred cows (Gyr xHolstein) in their second to fourthparities according to their calving tofirst service intervalsThe group where the calving to
first service interval was less than50 days had a positive nutritionalbalance and an optimumreproductive performance whereasthe group where it was greater than50 days had a negative energybalance and more open days Thus it was shown that adequate
levels of protein and energy arerequired to ensure normal uterineinvolution and start to ovarianactivity postpartum
Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling
Mastitis and arthritis in Alpine goatsIn this Croatian study (Vet Arhiv 87121-128) the prevalence and aetiology of subclinical mastitis wasevaluated in goats that wereseropositive for caprine arthritisencephalitis virus The connection to the occurrence
of clinical arthritis was studied in543 goats from intensive productionfarmsSome 508 of goats were
seropositive caprine arthritisencephalitis virus and subclinicalmastitis was found in 523 of thegoats Both findings were present in 30
Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

PathologyFollowing injury to the mucosal lining of the intestines malabsorption maldigestion and loss ofprotein and fluid occurs A secretory component to the diarrhoea contributes to further electrolyteand fluid loss Infections caused by Salmonella dublin can have respiratory signs
Factors that adversely affect the normal enteric flora tend to favour the growth of salmonellawhich are often present in very low numbers in the gastrointestinal flora of normal or carrieranimals These animals can infect their calves
Birth transport concurrent disease and feed or water deprivation which in turn reduces immunityandor can cause shifts in the enteric flora can cause a proliferation of salmonella In calvesantibiotics can cause shifts in the enteric flora and cause the proliferation of salmonella
Once a carrier cow is stressed large numbers of salmonella bacteria are shed and calves especiallynaiumlve ones are at risk This risk is magnified if crowding poor sanitation house location use ofcommon feeding implements concurrent disease or stress is present Calves with persistent BVDvirus infection are at a higher risk of succumbing to salmonellosis
Clinical signsCalves with salmonellosis typically have fever and diarrhoea Fresh blood and mucus in the faecesare also common In addition if the salmonella infects a certain part of the body swollen leg jointsand lameness (arthritis) nervous signs (meningitis) or pneumonia may be seen Salmonellosis canoccur sporadically in individual animals or endemically In calves it typically occurs between 2-8weeks of age If newborn calves deprived of their colostrum are brought together at one locationfrom different farms salmonellosis may appear as early as three days of age
A great variation in clinical severity occurs because of variation of the virulence ad infecting dose ofthe salmonella and the age immune status and concurrent diseases in the calf
Young calves have a greater risk of death because of septicaemia and fluid loss via diarrhoea whichleads to severe dehydration and electrolyte imbalances
The peracute form of the disease may cause death before diarrhoea is seen These calves have anabdominal distension as a result of rapid fluid loss into the small and large intestines and sometimesthe stomach They often die from a secondary bacteraemia and endotoxaemia for example causedby E coli

forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be
an excellent substitute for mined mineralnutrients such as phosphorus andpotassium There are a few companiescurrently installing systems that can providesaleable nutrients through fertiliserdistribution channels
Goals and outcomes
The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions
providers and farmers however do have theopportunity to partner up in spinningmanure into gold while benefitting thelivestock operation the neighbours and theenvironment n

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability

Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Omission teat preparationThis Irish study (Irish J of Aric andFood Res 55 169-175) was under-taken to investigate the effect ofomitting teat preparation prior tomilking on the bacterial levels in themilk immediately after milking andafter a period of storage (0 24 48or 72 hours at 4degC)The total bacterial count of the
milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Many of us remember the childhoodfairy tale of Rumpelstiltskin asmall man who helped a young
lady in distress spin straw into gold tosatisfy a king We can picture the woodenspinning wheel and large pile of goldenstraw and realise that this is impossible
by Andy Lenkaitis PEProduct Manager-Manure Management

How can a wasteful product like straw beturned into gold Many producers lookover their animals and operation with prideand clarity but when it comes to theirmanure system they may have the samehelpless feeling as the young millerrsquosdaughter sitting at the spinning wheel witha room full of strawThe difference between the origins of the
fairy tale and the reality of today is that wehave the technology to turn a once difficultto manage product like manure into alsquogoldenrsquo product for plants Manurecontains vital nutrients organic matter andbacteria that can be extremely beneficialwhen used properlyThe advances in soil testing predictive
forecasting and precision agriculture have
created a beautifully detailed picture ofnutrient levels field conditions andmanagement opportunities In addition ourunderstanding of nutrient conversion plantnutrient uptake and yield impacts provideus the knowledge and motivation requiredto better manage our manure andagronomic relationship
Manure separation
Primary separation of coarse particles andfibres has been used for various reasons ondairy farms Often the liquid effluent afterseparation is used back on the dairy foralley cleaning or stored in a lagoon to bespread through an irrigation system Whileprimary separation has a minimalinvestment the effectiveness of separatingnutrients into the liquid fraction is quitelow Over 90 of the nutrient valueremains with the liquid effluentFurther separation steps are required to
partition nutrients into different usablestreams One critical component ofseparation is to evaluate the cost and valueof creating a separate nutrient stream Wecannot expect to be profitable by goingthrough a process that takes one manurestream into multiple streams that wehandle in the same mannerThe system must create a solution to a
problem not create new ones Additionallywith any separation system nutrients arenot created or destroyed from the processthe same amount of land is needed to makeproper agronomic use of the nutrientsgenerated on the dairy One specific example is nitrogen some
systems reduce the amount of nitrogen lostto the atmosphere and as a result createadditional nitrogen to be accounted for in anutrient management plan This balanceactually works well since nitrogen is oftenthe limiting factor in corn yield however ifnitrogen and other nutrients can bestabilised and exported off the farm it cangenerate revenueCertain manure derived products can be

The sheer volume of material coupled withthe logistics of hauling have led producersto consider advanced separation systems Insome cases the motivation is regulatoryenforcement or environmental compliancedriven In addition to historic casesinvolving negligent use of manure nutrientsfrom livestock farms there are landmarkcases pending against traditional row cropnutrient practices that will lead to wideradaptation of cover crops and split nutrientapplication practicesRegardless of the motivation here are
some common goals of installing a systeml Concentrated nutrients in less volumebull Reduced manure hauling costs byspreading more liquid close to home

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different
building blocks of equipment from theabove list designed to work together forthe best performance and cost At this timesystems are installed and designed forcontinuous operation Mobile systemstraditionally do not have the throughputcapacity to meet the needs of modern farmsizes Building a modular system is beneficial as
farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and
nutrient partitioning system comes withmany benefits but those benefits comewith costs Unlike the millerrsquos daughter who had to
make a deal with a small man who helpedher turn straw into gold we do not have toguess Rumpelstiltskinrsquos name or be forcedto give up our firstborn childWe as in the equipment solutions

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

An investment to thoroughlyconsider
When evaluating a system a properbusiness case is critical to determine thesuccess and complexity of a system Capitaland operational costs of systems can bequite expensive and often inversely relatedto each other Certain filtration systemsmay be less expensive initially but can havehigh operational costs due to daily polymercosts cost to clean the equipment andpower consumptionMoreover some additional farm
equipment may be required to make use ofthe different streams from the processSome of the cost benefits of a system
cannot be measured directly and need acareful pencil to account forl Increased crop yieldsbull By timely nutrient applicationbull By being able to plant sooner or doublecropbull By reducing compaction on fields by nothauling during wet conditionsl Neighbourhood benefitsbull Reducing traffic during hauling season onthe roadbull Potential for reduced odourbull Environmental responsibility by betternutrient managementl Opportunity to create a saleable productfrom manure nutrientsl Potential for reducing manure storagerequirements (Manure-to-water systems)l The freedom to consider and chooseyour system before regulations are put inplace
System building blocks
Several advanced manure separationsystems are in operation across the globeLike manure from a farm each system isunique in design and operation Manysystems use technology adapted from thewaste water treatment industry withvarying levels of success Equipment mayincludel Slope screen separatorsl Gravity belt thickeners
l Screw pressesl Decanter centrifugesl Micro and vibratory screensl Dissolved Air Filtration (DAF) systemsl Membrane filtrationl Ammonia strippingl Reverse osmosisSystems are comprised of different

farms grow and regulations progresscreating different performance standardsover time Some master planning needs tobe done in the beginning but systems caneasily be added on to as needs and financeschange
Conclusion
As the equipment solutions provider andthe livestock producer look to design asystem the first step must be to establish apartnership understanding The livestockproducer needs to understand thatseemingly small management changes inthe barn can have detrimental effects tothe operation of the separation systemFrequency and amount of bedding cow
cooling and ration changes can change therecipe of the product to the separationsystem Additionally the separation systemneeds to be adaptable to changes in themanure and create products thateconomically fit into the farmsrsquo croppingsystemA functional manure separation and

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay
New data evaluating the effect ofrake-type on ash content of alfalfahay were presented at the lastMinnesota Nutrition Conferenceis study was conducted by aresearcher from University ofMinnesota on first cutting alfalfahay fields located in MinnesotaPennsylvania and Wisconsin Twoswaths of mowed hay wereconsolidated with a wheel rakeside-delivery rake rotary rake or amerger Hay merger consistentlyproduced bales having the leastamount of ash (114 98 and 92ash as percent of dry matter inMinnesota Pennsylvania andWisconsin respectively) while thewheel rake produced bales with thegreatest amount of ash (146 11195 ash in MN PA and WI)
Since ash content of alfalfa greaterthan 8 indicates hay has beencontaminated with soil theseresults suggest farmers looking toreduce ash content of hay shouldconsider using a hay merger whencombining swaths

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Since 1929 the Antoniades familyfarm in Pissouri Cyprus has main-tained an international reputationfor successful selective breeding ofCyprus Damascus (Shami) goatsOver the past 70 years this pro-
gram has been developed as a semi-intensive production system with anemphasis on strengthening thegenetic line that favours productionand adaptability
cyprusshamigoatscom
Genetic strength has beenachieved by ensuring a large pool ofanimals to support frequentreplacement of breeding stock We have already established solid
export markets all over the MiddleEast Gulf States and North Africaand are developing export and part-nership breeding opportunities withseveral new partners elsewhere
The Cyprus Damascus (Shami) goatis a highly adaptive and prolific ani-mal that is recognised as the ulti-mate goat in either dual or singlepurpose production systems The Antoniades herd produces an
average litter size of 25 kids perpregnancy with kids averaging birthweights of 45kg The newborn kids feed from their
mothers for the first two days toensure that they receive adequatecolostrum They are then separatedfrom their mothers and feed fromartificial kid feeders supplementedconcentrates until 49 days By four months of age females
achieve an average weight of 30-32kg and males an average of 35kgAdult weight ranges between 60-90kg and bucks 90-130kg At four months animals selected
into their production system areseparated from the remaining herdand enter an intensive immunisationand veterinary surveillance programfocused on enhancing reproductionFemales are presented to the
bucks at the first oestrus (between220-270 days) and continue breed-ing for an average of six years afterwhich they are sold to other localfarms or used for meat Does that are used for meat pro-
duction can achieve three gesta-tions in 24 months while those inthe milk production system arepresented to the Buck at 215 dayspost partum The company aim to milk for 305
days unless they are pregnant whenthey remove them from the milkproduction system three monthsbefore their expected delivery date Their bucks begin mating from
nine months and remain in the pro-duction system for a maximum of

is an excellent highly adaptive andhardy goat Experience locally and in export
countries confirms that it can beused as a purebred or in cross for
milk andor meat production sys-tems surpassing the production fig-ures of equivalent animals inintensive semi-intensive or exten-sive systems The company already have experi-
ence exporting Cyprus Shami overthe last 20 years in more than 15Middle East and Gulf StatesEverywhere that they send theCyprus Shami it reproduces theseamazing production figures Detailed studies in Libya demon-
strate that these figures are main-tained in pure bred or cross-matedF1 generations with equivalentbreeds in destination countries aswell as local animalsThe company recommends these
goats for private breeders who wishto raise a pure herd as well as forrural agricultural development pro-grams internationally It is also ideal to support genetic

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set
there is a need to focus on anti-microbial resistance and a need to

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

dairy news from around the world
calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

growth of epithelial cells that form the toplayer of the skin The originally inorganicmolecules Cu2+ and Zn2+ are covered(chelated) with an organic layer thatprovides unique propertiesIn a recent randomised clinical trial on 231
severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water
intake reduced milk yield normalbody temperature and normal feedintake should be suspected of beinginfected with Schistosoma nasale
NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

Of the total sample 219 wereseropositive to caprine arthritisencephalitis virus and had clinicalarthritis
These results suggest that caprinearthritis encephalitis virus could beone of the main reasons for theoccurrence of clinical arthritis in thestudied herds
Omission teat preparationThis Irish study (Irish J of Aric andFood Res 55 169-175) was under-taken to investigate the effect ofomitting teat preparation prior tomilking on the bacterial levels in themilk immediately after milking andafter a period of storage (0 24 48or 72 hours at 4degC)The total bacterial count of the
milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis
asynchrony in the occurrence oflactation and dry matter intake Inthe tropics this scenario is exacer-bated due to poor quality and dietshortagesThis Colombian study (Arquiv
Brasil de Med Vet e Zootec 69 1-9)looked at the nutrition andbehaviour of cross bred cows (Gyr xHolstein) in their second to fourthparities according to their calving tofirst service intervalsThe group where the calving to
first service interval was less than50 days had a positive nutritionalbalance and an optimumreproductive performance whereasthe group where it was greater than50 days had a negative energybalance and more open days Thus it was shown that adequate
levels of protein and energy arerequired to ensure normal uterineinvolution and start to ovarianactivity postpartum
Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling
Mastitis and arthritis in Alpine goatsIn this Croatian study (Vet Arhiv 87121-128) the prevalence and aetiology of subclinical mastitis wasevaluated in goats that wereseropositive for caprine arthritisencephalitis virus The connection to the occurrence
of clinical arthritis was studied in543 goats from intensive productionfarmsSome 508 of goats were
seropositive caprine arthritisencephalitis virus and subclinicalmastitis was found in 523 of thegoats Both findings were present in 30
Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set
there is a need to focus on anti-microbial resistance and a need to

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water
intake reduced milk yield normalbody temperature and normal feedintake should be suspected of beinginfected with Schistosoma nasale
NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

Of the total sample 219 wereseropositive to caprine arthritisencephalitis virus and had clinicalarthritis
These results suggest that caprinearthritis encephalitis virus could beone of the main reasons for theoccurrence of clinical arthritis in thestudied herds
Omission teat preparationThis Irish study (Irish J of Aric andFood Res 55 169-175) was under-taken to investigate the effect ofomitting teat preparation prior tomilking on the bacterial levels in themilk immediately after milking andafter a period of storage (0 24 48or 72 hours at 4degC)The total bacterial count of the
milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

levels of protein and energy arerequired to ensure normal uterineinvolution and start to ovarianactivity postpartum
Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling
Mastitis and arthritis in Alpine goatsIn this Croatian study (Vet Arhiv 87121-128) the prevalence and aetiology of subclinical mastitis wasevaluated in goats that wereseropositive for caprine arthritisencephalitis virus The connection to the occurrence
of clinical arthritis was studied in543 goats from intensive productionfarmsSome 508 of goats were

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Udder cleft dermatitis (UCD) in dairycattle is a serious skin conditionmainly located at the front junction
of the udder and the abdomen and inbetween the front udder quarters
by Gerwen Lammers Carly Vulders and Robbert van Berkel
Intracare BV The Netherlandswwwintracarenl
The affected skin has a moist and redappearance may be covered with a crustand this is often accompanied by a foulodour In the global shift to more intensivefarming systems udder cleft dermatitis is aworldwide growing problem A farmertypically only detects the severe casesmaking the incidence often higher than hethinks
The disease leads to a decreased welfareand milk production premature culling andeven death of the animal The Dutch AnimalHealth service reported that udder cleftdermatitis was present on 80 of 20randomly investigated dairy farms with aprevalence ranging from 0-15 They
reported an association with udder shapeproduction level and the use of a footbath However the exact cause of thedisease is still under investigation
Although the primary cause of the diseaseis still under investigation the secondarycolonisation of the wound by opportunisticbacteria hamper the natural healing processof the compromised skin It has beensuggested that the Treponeme bacteria thatcause digital dermatitis may play a role butthis has been disproven by others
Treatments including sprays containingantibiotics or conventional zinc aredisappointing The use of antibiotics isfurther problematic because of thedevelopment of antibiotic resistance andthe risk of antibiotic residues in the milk
The goal of this study was to investigatethe effect of a spray containing bactericidalcopper and skin regenerating zinc both inchelated form on the healing of severecases of udder cleft dermatitis
Non-antibiotic spray
Intra Repiderma is a non-antibiotic aerosolspray that is based on copper and zinc for
which no MRL value is applicable and thusno withdrawal period Copper isbactericidal and stimulates the formation ofnew blood vessels which is an importantfeature of the wound healing process
Zinc supports the natural regenerativecapacity of the skin and stimulates the

growth of epithelial cells that form the toplayer of the skin The originally inorganicmolecules Cu2+ and Zn2+ are covered(chelated) with an organic layer thatprovides unique propertiesIn a recent randomised clinical trial on 231
severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set
there is a need to focus on anti-microbial resistance and a need to

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)

American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

growth of epithelial cells that form the toplayer of the skin The originally inorganicmolecules Cu2+ and Zn2+ are covered(chelated) with an organic layer thatprovides unique propertiesIn a recent randomised clinical trial on 231
severe DD lesions in dairy cows on sevendifferent farms it has been demonstratedthat Intra Repiderma has a cure rate of868 and is with half as many treatments19 times more effective than antibioticspray Because of these positive results of the
spray on bacteria-infected digital dermatitisskin lesions additional pilot studies wereperformed on a couple of severe cases of
udder cleft dermatitis in Germany TheNetherlands and Canada
Case studies in different countries
l Germany In Germany the spray was evaluated on afarm located in the Leipzig area that wassuffering with a large numbers of affectedanimals Spraying was performed once a week for
multiple weeks on 20 animals The disease-specific odour significantly reduced afterthe first treatment The appearance of the lesions also
improved and the treatment protocol
resulted in partial healing but no completere-epithelialisation was observed It was therefore concluded that a more
intensive treatment schedule was requiredfor this severe cases of udder cleftdermatitis
l The NetherlandsIn The Netherlands four animals withsevere chronic udder cleft dermatitis weretreated daily for two weeks Three of thefour animals demonstrated completehealing the size of the wound of the otheranimal had decreased by approximately80
l Canada In Canada one animal with an extremelysevere chronic case of udder cleftdermatitis was also treated daily with thespray Due to the severity of the lesion thiswas for a duration of two months Withintwo weeks the area changed to a more dryand quiet appearance After two months the skin had almost
closed No adverse effects were observedduring any of these tests
Practical considerations for use
Before the first spraying it was found to bevery important to carefully clean thewound with water and afterwards dry itwith a piece of paper Then start with covering the affected area
and the surrounding tissue by spraying oncein the morning and once in the eveningfollowed by spraying once a day Copper and zinc are exempted from
residue studies but do not use the milkwhen spraying in close proximity to theteats because of the presence of strongcolouring agents
Conclusion
Cases of udder cleft dermatitis only changeat a very slow rate Natural recovery ispossible but was found to be three timesless likely for severe than for mild lesionsThe cases treated in this report fell in the
worst category since farmers are typicallyonly willing to test new treatment optionson chronic cases that do not have anyhealing options leftThe primary cause of UCD still requires
further investigation but the positiveresults obtained on these severe casesjustify the further investigation of zinc tostimulate skin regeneration and copper toeliminate secondary wound infections incases of udder cleft dermatitis Intra Repiderma is an effective and safe
alternative for antibiotic spray for thetreatment of udder cleft dermatitis n

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Antibiotics are one of the mostimportant therapeutic discov-eries in medical history They
have contributed to reducing mortality and morbidity from bacterial disease in mankind live-stock and pets Today althoughantibiotic resistance is not a newphenomenon there is internationalconcern around the rise in drugresistant infections and public recommendations to restrain theuse of antibiotics
Correct use on the farm
The answer to preserve theseimportant therapeutics is not tosimply reduce the volumes used Itis about implementing their judi-cious responsible and correct use indaily veterinary routines on thefarm Combating resistance requiresa lsquoOne Healthrsquo approach integratingamongst others animal health public health food and the envi-ronment
These were the opening words onthe programme for the symposiumentitled Aim Before You Shootwhich was recently hosted byHuvepharma in BulgariaOne of the practical papers was
entitled Antimicrobial treatment ofbovine respiratory diseases and waspresented by Irish veterinarianMichael Sexton He comes from a 13veterinarian group that has a 50cattle base of which 95 (approxi-mately 300 herds) is dairy Irelandhas more cattle than people (642
vs 475 million) There are some17000 dairy herds which is a markedreduction from the 144000 thatthere were in 1975A typical Irish dairy farm has 70
cows which calve between Januaryand April Typically most cease milkproduction in November and arehoused from November to Marchtherefore their milk productioncomes from grassThe common disease syndromes
seen by Michael are shown in Table1 and their aetiologies involve RSVPI3 IBR and BVD (all viruses) thenematode parasite Dictyocaulusviviparous and various bacterialinfections (often secondary infections)Common bacterial isolates
include Mannheimia haemolyticaPasteurella haemolytica andMycoplasma bovis Laboratory based diagnostic tools
are infrequently used for the following reasons Most infections are mixed viraland bacterial ones Most decisions for drug choiceare experience based Most post mortems show pasteurellosis which is seldom the primary cause Swabs may not detect all theviruses present
Antibiotic choice takes intoaccount the duration of the treat-ment and the route of administra-tion Antibiotic treatments fall intothree categories One off administrations Theseinclude certain macrolide and sometetracyclines Periodic repeated doses such asflorfenicol Daily treatments including tetra-cyclines quinolones and amoxicillins
Then there are the criticallyimportant antibiotics which areassociated with resistance problemsin man and should not be usedThese include the fluoro-
quinolones the third and fourthgeneration cephalosporins and col-istin When it comes to supportive
therapies the main drugs used areanti-inflammatories such as NSAIDSand steroid based products
Where hoose is a factor an appro-priate wormer is used Also used arediuretics mucolytics and bronchodilators
Michael feels that it is importantto have a treatment strategy forfarms This should centre around Isolation of sick animals Elimination of chronic non-responders Having a policy for purchased animals- Quarantine where possible- Administration of a long actingantibiotic- Administration of ananthelmintic- Vaccination
When it comes to treatinganimals he is strongly against treat-ing the whole group but prefers aprevention approach that focuseson the following Good prevention strategies Good stockmanship Smaller groups Good housing- Good air quality and circulation- No chilling draughts- Correct environmental temperature- Correct stocking density- Dry bedding- Correct roof height
Vaccination
However he would treat theremainder of the group when Other animals show clinical signs The initial clinical case is severe If the condition is acutechronic If there is a high animal density In situations where managementis deficient
Preventing disease is all about prevention management and keypoints here are Adequate housing Not turning calves out too early Appropriate anthelmintic use atgrass Correct weaning strategy Correct timing of housing Management of purchased stock Good biosecurity practices
The disease prevention or prophylaxis part of this is importantand centres around A neonatal calf vaccination programme A re-weaningpre-housing vaccination programme Vaccination for IBR Anthelmintics for primiparouscows calves and weanlings Very selective use of antibiotics
As far as the future is concernedhe sees the following trends emerging Earlier detection with automaticfeeders More neglect on bigger units Some good drug developmentsover the next 15 years Better housing is the single mostimportant factor Better use of vaccination programmes ndash problems with neonatal BRD
Ireland now has a National ActionPlan on Antimicrobial Resistance for2017-2020To help achieve the targets set
there is a need to focus on anti-microbial resistance and a need to

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment
Nasal schistosomiasis inmurrah buffaloesThis Indian study (Buff Bull 36 143-145) found the incidence of thenasal worm Schistosoma nasale tobe 8 among healthy animals and92 in animals diagnosed withschistosomiasisBuffaloes showing reduced water

NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies
Mammary gland developmentduring pregnancyIn the mammary gland genetic circuits controlled by oestrogenprogesterone and prolactin act inconcert with pathways regulated bymembers of the epidermal growthfactor family to orchestrate growthand morphogenesis during pubertypregnancy and lactation
American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling
Mastitis and arthritis in Alpine goatsIn this Croatian study (Vet Arhiv 87121-128) the prevalence and aetiology of subclinical mastitis wasevaluated in goats that wereseropositive for caprine arthritisencephalitis virus The connection to the occurrence
of clinical arthritis was studied in543 goats from intensive productionfarmsSome 508 of goats were

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of
cow preference and behaviour Potential areas of concern for the pasturebased system include physiological indicators of more severe negativeenergy balance and in some situations the potential for compromisedwelfare due to exposure to unpredictable weather conditions Overall it was concluded that there are considerable animal welfare

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

dairy news from around the world
calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Neonatal enteritis
A presentation entitled Anti-microbial treatment of neonatalenteritis in calves was given by DrIngrid Lorenz from the BavarianAnimal Health ServiceIngrid considers neonatal gastro-
enteritis to be a multifactorial disease in which the calf interactswith its environment its nutritionand viruses bacteria and protozoaand is a major cause of mortality inyoung cattle under six months old
Its causes include enterotoxigenicE coli which produce various tox-ins various viruses some of whichcan destroy epithelial cells liningthe gut and substances that act likeenterotoxins the parasite cryp-tosporidium which damages entericvilli causing malabsorption and ultimately resulting in severe diarrhoea and dehydration
When it comes to treatmentsIngrid stressed the importance ofthe following The replacement of fluids byusing electrolytes and buffers
Oral electrolytes should only beused when calves are still drinkingand lt8 dehydrated Intravenous fluid therapy Continuous milk feeding Use of anti-inflammatories suchas NSAIDs
When it comes to using antibiotics she highlighted that sickcalves with diarrhoea have anincreased risk of developing E colibacteraemia or septicaemia andthat calves with enteritis due to salmonella can be assumed to be
bacteraemic Therefore treatmentshould be aimed against Gram nega-tive bacteria in the blood and thesmall intestines and such treatmentshould preferably be parenteral Two further points were that
faecal bacterial cultures and AMRsusceptibility testing is not a usefulexercise in calves with neonataldiarrhoea and in casesoutbreaks of diarrhoea due to salmonella treatment should be based on susceptibility testing resultsThe first choice antibiotics for ill
calves with diarrhoea where it isthought that infection has spreadinto the body are ampicillin amoxicillin or a potentiatedsulphonamide Fluoroquinolones and third or
fourth generation cephalosporinsshould not be used and if they arethey should only be used under veterinary direction If there is noevidence of systemic illness the calfshould not receive antibiotics andthey should be monitoredPrevention is always better than
cure and this can be centred on vaccination of the mothers and thepossible use of halfuginone Finally remember the 1-2-3 of
colostrum ndash use colostrum fromthe 1st milking for the 1st feed andgive it within 2 hours of birth ensur-ing that each calf gets at least 3litres of colostrum n

Timothy Walsh from the University of Cardiff reflected on the globalspread of antibiotic resistance He gave some interesting observations
If antimicrobial resistance is not tackled soon by 2050 the human deathrate could be one death every three seconds That is in 2050 there willbe 10 million such deaths compared to 700000 today
Meropenem a carbapenem antibiotic which is used to treat multi-drugresistant infections in man can be bought online without prescription
A comprehensive resistome analysis published in 2016 revealed a highprevalence of multi-drug resistant E coli carrying the MCR-1 gene inChinese poultry production
We should not underestimate the role of wildlifewild birds in theglobal transmission of antimicrobial resistance genes
Animals in the USA consume 70 of medically important antibiotics forman
A major contributor to antimicrobial resistance is poor governance andcorruption

This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Milking systems for sheep and goats This Swiss review (Forum Klein-wiederkaumluerPetits Ruminants 10 6-7) looked at some of the guide-lines for an effective milking systemfor sheep and goats Some of the factors that can
impact on milk quality included thecondition of vacuum pumps noisevibrations the electrics and theoverall condition of both theanimals and milking equipment

intake reduced milk yield normalbody temperature and normal feedintake should be suspected of beinginfected with Schistosoma nasale
NEFA BHB and reproductiveperformance This Algerian meta-analysis(Theriogenology 93 99-104)included the results from36 differ-ent statistical models from 14papers It evaluated the associationbetween elevated non-esterifiedfatty acids (NEFAs) andor β-hydroxybutyrate (BHB)
This meta-analysis failed toclearly conclude on an associationbetween oestrus cyclicity and highnon-esterified fatty acids or β-hydroxybutyrate
This work allowed a new overviewon the association betweenhyperketonaemia and reproductivedisorders and performance Itconcluded that this topic requiresfurther epidemiological studies

American work (PLos Genetics 13(3) e1006654) has identified the CUBand zona pellucida-like domain-containing protein 1 (CUZD1) whichis expressed in mammary ductal andalveolar epithelium as a novelmediator of mammary glandproliferation and differentiationduring pregnancy and lactationThis coupled to other work
suggests that CUZD1 plays a criticalrole in prolactin inducedJAKSTAT5 signalling that controlsthe expression of key STAT5 targetgenes involved in mammaryepithelial proliferation anddifferentiation during alveolardevelopment

milk was not affected by teatpreparation prior to milking
Toxoplasma gondii in EstoniaIn this Estonian study (Vet Parasit236 137-143) sera from 3991 animalson 228 farms were studiedThe animal level seroprevalence
was 1862 with at least oneseropositive animal occurring on6886 of farms
The seroprevalence rateincreased with cow age Whetherthe farm was dairy or beef did notinfluence the level of seropositivityfor Toxoplasma gondii The odds of finding at least one
animal seropositive for T gondiiwere higher on the larger thanaverage farms
Claw disorders and subclinicalmastitis This Egyptian clinical study (VetWorld 10 358-362) was undertakento study the associations betweeninfectious and non-infectious clawdisorders and subclinical mastitisand involved 43 cowsA cow was considered to have
subclinical mastitis if at least onequarter gave a positive Californiamastitis test result The results are summarised in the
table belowIt was found that the occurrence
of claw disorders had a significantcorrelation with subclinical mastitis

Somatic cell countThis Costa Rican study (Agro Costa40 7-18) evaluated the effect ofgenetic and environmental factorson somatic cell counts It used198685 daily records from 43535 lactations involving 23749 cows in237 herds of three breedsA consistent downwards trend
was seen in somatic cell countsbetween 2004 and 2015 A non-linear pattern to somatic cell countsthrough lactation starting at 37 witha marked decrease to 31 at 60 dayspostpartum and then increasing to amaximum of 39 around the 365thday postpartumReliabilities in breeding values for
cows and bulls were 040 and 044respectively indicating thatbreeding could play a role inimproving somatic cell countsalongside cow culling

Various reasons are put forward to support the continuous housing of dairycows yet the welfare of dairy cows is typically perceived as being better inpasture based systems This review (Animal 11 261-273) compares the healthand welfare of cows in these two systemsWelfare is reviewed under the headings of health behaviour and
physiology Regarding health cows in pasture systems had lower incidenceof lameness hoof lesions hock lesions mastitis uterine disease andmortality Pasture access also had benefits for cow behaviour in terms ofgrazing improved restinglying times and less aggression When given achoice been the two systems the pasture based one was favoured by thecows However the review highlighted the need for a deeper understanding of

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Milk fever (hypocal-caemia) is caused bycalcium deficiency
which arises when the dairy cow hasjust calved and now has to producelarge amounts of milk It mainly hitscows in third or greater lactationswhere approximately 8-12show clinical symptomsand up to 50 of thehigh yielding dairy cowscan have subclinicalhypocalcaemia Dairy cows suffering frommilk fever have a high risk for otherdiseases such as retained placentainfections ketosis or mastitis In thetime period shortly before and aftercalving large amounts of calciumare removed from the blood to themilk and the rapid drop of calciumand the failure to increase calciumabsorption fast enough may resultin milk fever with symptoms such aslack of appetite low body tempera-ture and muscle tremors
CaliBol from R2Agro is formulatedin a unique bolus form which pro-vides 40g of highly bioavailable calcium as a combination of cal-cium chloride and calcium propi-onate The calcium bolus is rapidlydissolved in the rumen fluid and
subsequently the calciumsalts are released di-rectly to the rumenfluid and absorbedinto the blood The benefits ofCaliBol include
l Easy quick and clean administra-tionl Highly bioavailable calcium supplementl Rapid dissolving in the rumen l Non-corrosive to the mucousmembranes of the rumen l No risk of misswallowing and hydrothorax ndash and no waste l No unpleasant bitter taste likegels and pastes

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay

In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration

Harvesting high quality alfalfa hayAlfalfa preserved as hay requiresabout 2-4 days or more of fieldwilting depending on weatherconditions Faster drying allows forhigher quality and reduces thethreat posed by rain Of the initialavailable protein in the standingcrop 28 can be lost under goodconditions and 46 when rainedon Additionally reducing thelength of time the swath stays in thefield allows for faster re-growth ofalfalfa
Dry matter and quality lossesduring harvest and storage of alfalfahay can be large Dry matter lossesfor the full process are typically 15-25 for hay made under gooddrying conditions and 35-100 forrain damaged hay Mechanicallosses account for nearly one thirdof total dry matter losses Mowingraking and baling shatters leavesand disassociates some small stemparticles Raking accounts for thelargest losses when compared to allfield operations Dry matterconstituents with the highestnutritive value for cows (leaves) aremost susceptible to losses
e following managementpractices improve the quality of thealfalfa hay by speeding up dryingand minimising leaf lossbull Cut forage into a wide swath thatcovers at least 75 of the cut areabull Keep a cutting height greater thantwo inches so air flow increasesunderneath the windrow bull Rakemerge swaths into awindrow when moisture content inthe forage is above 40
Hay producers have a wide varietyof equipment options to rake andmerge swaths or windrows Rakesand mergers can be evaluated basedon field losses drying rateswindrow shape ability to movelarge swaths and ability to create awindrow free of rocks soil andother debris Selecting the properequipment and adequate operationensures high quality hay
New data evaluating the effect ofrake-type on ash content of alfalfahay were presented at the lastMinnesota Nutrition Conferenceis study was conducted by aresearcher from University ofMinnesota on first cutting alfalfahay fields located in MinnesotaPennsylvania and Wisconsin Twoswaths of mowed hay wereconsolidated with a wheel rakeside-delivery rake rotary rake or amerger Hay merger consistentlyproduced bales having the leastamount of ash (114 98 and 92ash as percent of dry matter inMinnesota Pennsylvania andWisconsin respectively) while thewheel rake produced bales with thegreatest amount of ash (146 11195 ash in MN PA and WI)
Since ash content of alfalfa greaterthan 8 indicates hay has beencontaminated with soil theseresults suggest farmers looking toreduce ash content of hay shouldconsider using a hay merger whencombining swaths

Global palm oil short-ages have increasedthe cost of rumen-
protected fats by up to 40 in thepast 12 months Unless steps have been taken toreduce reliance on protected fats itis adding as much as pound900monthto the feed bill for a typical 200cow herd claims KW nutritionist DrMatt WittEl Nino weather patterns inMalaysia and Indonesia last year cutthe palm oil production by 39 mil-lion tonnes (mt) against a back-ground of rising global demandMatt told International Dairy Topics Production is expected to re-
bound 5-6mt this year but globalstocks will not fully recover until atleast 2018rdquo he addedIn terms of feed choice addinghigh sugar liquid feeds such as Molale will boost both rationpalatability and rumen microbial activity while switching to slowerfermenting starch feeds like soda-wheat can improve rumen condi-tions and fermentation efficiencyAdding supplements designed toenhance digestion and raise intakescan also be highly effective The plant extract-based OptiPar-tum-C for example can be usedweight-for-weight to reduce pro-tected fat in the diet by half with-
out any reductions in milk yieldmilk quality or fertility yet costs upto pound350t less

calving is an excellent strategy That is because it can helpprevent a rapid decline in blood calcium around calving andimprove cow health and performance in the subsequentlactation This approach helps reduce metabolic challenges likehypocalcaemia (clinical and subclinical) This is beneficial becausecows with hypocalcaemia often experience a depressed immuneresponse and are also susceptible to reduced skeletal andsmooth muscle function This predisposes cows to displacedabomasum metritis mastitis and other challenges
Interestingly when it comes to DCAD lower is not necessarilybetter Recent research conducted at the University of Florida hasfound that it is not necessary to reduce ration DCAD levels inprepartum diets beyond -12
DATA DETAILSThe study shows that pushing DCAD levels beyond -12 did notshow any positive effects on cow health and performancemeaning it only becomes an added expense During the studythe researchers fed prefresh Holstein dairy cows a ration with anegative DCAD of either -7 meq100g ration DM or -18meq100g ration DM for either the last 21 days or 42 days ofgestation They found that feeding a more negative DCAD diet ndashregardless of duration ndash adversely affected key metabolic andperformance parameters of blood base excess and dry matterintake Specifically data showed that reducing the level ofnegative DCAD from -7 to -18 meq100g ration DM
bull Reduced prepartum dry matter intake by 14-22kg per daybull Induced a more exacerbated metabolic acidosis prepartum
ldquoThe negative DCAD diet reduced dry matter intake prepartumas expectedrdquo explains Dr Joseacute Santos research foundationprofessor University of Florida Department of Animal SciencesldquoThat is an anticipated response based on all the literatureavailablerdquo
Ultimately the data suggest that there is no apparent reason whyyou should feed a negative DCAD diet more than -12meq100gration DM and DCAD of -8 to -10 appear to do the same job
DOES TIMING MATTERThese latest data reinforce previous research and indicates thatdairies can feed negative-DCAD diets longer than 21 dayswithout any negative effects Again no differences in energycorrected or fat corrected milk was observed in the cows fed thenegative DCAD diet for the 42-day dry period
In the long run all cows benefited from the negative-DCAD dietregardless of how long it was fed The data offer compellingevidence that dairies that are unable to group cows separately orfeed multiple rations during the dry period can still benefit froma negative-DCAD ration
