2 Ent teen Slenkdalkoors elke winter Oorspronklik gepubliseer in AgriOrbit 19 May 2018 Marika Brits - AgriOrbit Die Slenkdalkoors geval in Jacobsdal is op die stadium n geïsoleerde geval en die risiko vir verspreiding is laag. Dit is volgens Nelius Ferreira van die Vrystaatse Dieregesondheidsforum. Die Departement van Landbou, Bosbou en Visserye het die afgelope week die voorkoms van Slenkdalkoors op n plaas in die Jacobsdal omgewing in die Vrystaat bevestig. Volgens die Departement se verklaring is dit die enigste plaas waar die siekte aangemeld is en word verdere ondersoeke nou deur plaaslike veeartsenykundige dienste uitgevoer. Die uitbraak kan toegeskryf word aan verhoogde reënval, wat n toename in muskiete veroorsaak het. Ferreira sê dat die feit dat die uitbraak aan die begin van winter gebeur het, beteken dat daar n baie goeie kans is dat dit n geïsoleerde geval sal bly. Winter is reeds hier en hopelik gaan ons binnekort nog genoeg ryp kan kry om alle muskiete en muggies wat die siekte versprei te dood. Hy herinner egter aan 2010, toe n groot uitbraak in die somerseisoen gevolg het op n geïsoleerde geval in die winter. Om dit te voorkom moet daar in die komende wintermaande teen Slenkdalkoors geënt word. Inenting teen die siekte bly die beste verweer en jaarlikse enting moet n algemene praktyk in die boerdery wees. Dit is ook baie belangrik om moontlike gevalle aan te meld. Rapporteer skielike vrektes en aborsies aan jou plaaslike veearts en staatveearts, maan hy. Fereira stel ook die verbruiker gerus. Volgens die Wêreldorganisasie vir Dieregesondheid (OIE) is dit n soönotiese siekte wat slegs na mense oorgedra kan word deur muskietbyte of kontak met liggaamsvloeistof, weefsel van Slenkdalkoors-besmette dooie diere of fetusse of deur ongepasteuriseerde (rou) melk en rou vleis van besmette diere in te neem. Hy beklemtoon dus dat rooivleis wat op winkelrakke beskikbaar is steeds baie veilig is om te gebruik en dat n Slenkdalkoorsbesmette karkas nie vleisinspeksies sal slaag nie. Solank jy vleis by n betroubare slaghuis of kleinhandelwinkel koop, is dit veilig om te eet. Daar is dus geen rede vir kommer by die produsent of verbruiker nie. Produsente moet kalm bly en sorgvuldige beheer toepas op aspekte wat hul kan beheer. Dit beteken om getrou jaarliks alle diere teen die siekte in te ent.

3 Young chick feeding for Poultry World 2 May 2018 Early nutrition in chicks is important in order to meet their needs for initial fast growth rates as well as the development of their gut. This, in turn, will influence their ability to digest and assimilate nutrients. Nutrition of the chick begins in the egg, where the embryo is nourished by the yolk. The quality of nutrients within the egg will depend on the age of the breeder hen and her own nutritional intake. For example, antioxidant supplementation in breeder diets is important for the transfer of important vitamins and minerals to the yolk, which has been shown to improve hatchability and day-old chick quality. Omega-3 fatty acids can be increased in hen diets which will raise these levels in the egg to be used as an energy source for the embryo. First line of defence The health of day-old chicks and their resilience to disease depend on the amount and types of immunoglobulins (Ig) transferred from the hen during egg formation and when the embryo swallow s amniotic fluid during development. This provides the first line of defence for the young birds whilst they develop their own acquired immunity via the development of the specific tissues and cells in response to environmental and ingested stimuli. Active mannan-oligosaccharide optimal gut health However, immune status in the breeder hens may not always be optimal, and extra supplementation with products such as Actigen has been proven to stimulate natural defences, which are then transferred to the egg in proportionally higher levels. The active mannan-oligosaccharide (MOS) in the product binds bacteria in the gut and activates the immune system by presenting the bound bacteria to M cells in the gut wall, thereby supporting optimal immune function and maintaining health status. Actigen has been shown to be important in switching on certain genes involved in immune function. These functionalities explain why animals supplemented with this product have higher levels of circulating Ig in blood, and promotes the transfer of maternal antibodies to progeny.

4 Newly hatched chicks are often subject to environmental stress, for example during transport for placement. Photo: Alltech In ovo supplementation In ovo supplementation given directly into incubating eggs has been investigated since the early 2000s and has focused on supplementing the developing embryo with energy and mineral sources. However, other trials have used Actigen via injection into the amniotic sac and demonstrated an increase in hatchability from 82.5% in the control (saline-injected only) to 97.5% for those injected with 5 millimolar of the product. Vaccination: Chicks need functioning immune systems Vaccination remains an important procedure for the control of common diseases, especially in young birds. However, they need to have a functioning immune system in order to assimilate the vaccine and respond accordingly to gain full disease protection. Research trials have shown that optimal immune function influences the response of young chicks to infectious bursal disease (IBD) vaccination, increasing the antibody titre from 659 in chicks from unsupplemented hens up to 969 for those hens receiving the additive. Improved immunity in young chicks via these types of interventions may be important in ensuring optimal gut development. Feeding trials examining the benefits of the supplement, in which birds were raised to 12 days of age on litter from previous flocks with poor gut development, showed that the birds on the Actigen diet had significantly higher body weights and better flock uniformity. Environmental stress Newly hatched chicks are often subject to environmental stress, for example during transport for placement. A trial was conducted using dexamethasone injections to mimic these typical physical stress responses seen in birds. This treatment reduced chick growth, with significant differences (P<0.01) in body weight at day 14 (368 grams for injected birds versus 433 grams for the control). when the birds were supplemented with the product and subjected to the same treatments, there was no significant difference between the injected or the control birds at the same age. Digestion in young chicks In young chicks, digestion can be poor because of lack of enzyme activity in the first days post-hatch. During the first 48 hours after hatching, the digestive tract in chicks increases in weight by 110%, and most of the enzyme activity is based on lipase for fat digestion from yolk sac reserves. The first 7 days represents 17% of the whole growing period of a broiler, during which the bird attains 10% of its final body weight. This requires high levels of digestion to support nutrient uptake. Increase in enzyme activity Feeding Actigen to broilers has been shown to significantly increase enzyme activity in the gut, namely maltase and alkaline phosphatase in the jejunum, ileum and caecum, and sucrase in the jejunum and caecum. These are important brush border enzymes that facilitate the final breakdown of nutrients, allowing better absorption into the hepatic portal vein. Such an increase in enzyme activity in young birds, which lack the ability to secrete required levels of enzymes in their gut during the first few days post-hatch, will therefore have a major impact on its nutrient assimilation from the feed.

5 The establishment of correct bacterial profiles has been investigated in young animals, including chicks, in many published reports. The ability of the additive to participate in normalising gut microflora is important in starter diets, as initial exposure to bacteria from the environment, as well as feed and water supplies, makes the young bird vulnerable to colonisation by these undesirable entities. Prevention of colonisation has multiple benefits for the bird. It contributes to the development of the gut and immune system. A correct microfloral profile is able to better withstand any challenges because of its ability to outcompete other ingested organisms. Recent reviews have highlighted the benefits of improved bacterial profiling via the modes of action of the active MOS in Actigen and discussed the benefits reported from many trials on poultry at different ages, including young birds. Because chickens face many challenges to their health and growth potential, especially when newly hatched, supplementing their starter diets with the additive provides the best feed platform for ensuring good growth and low mortality during the first week post-hatch. Optimised microflora in the lumen of the gut helps reduce the toxin load, which can damage the absorptive surface and cause diarrhoea and increased mortality. For specialised prestarter diets, using the described product in the formulation is particularly important to attain the relatively large growth rates and development that is typical at this age. Giving chicks a good start through technical feeding strategies is essential for efficient productive performance and economic returns on-farm. Originally posted in Poultry World

6 3 benefits of fats in horse Originally posted in all about feed 20 April Do horses need fat and oils in their diet and what are the benefits for these animals? Kentucky Equine Research reports that even though they don t have gallbladders, horses digest fat well if it is introduced slowly into the diet. As it turns out, horses benefit from fat in several ways. According to Catherine Whitehouse, nutrition advisor at Kentucky Equine Research, Dietary fat is necessary for the absorption of the fat-soluble vitamins, A, D, E, and K, but it has also turned out to be a useful feedstuff above that. 3 benefits from fats in horse diets: diets 1. Fats have a role in vitamin absorption 2. Fats are an energy source and contain more calories than carbohydrates. It can be an alternative energy source for horses that require limited carbohydrates, such as horses suffering from certain muscle diseases and those prone to laminitis. 3. Fat supplies omega-3 and omega-6 essential fatty acids. Some commercial feed companies produce fat supplements that may be extruded or pelleted. Photo: Dreamstime

7 Adding fat to the horse diet can be done by top-dressing a concentrate with oil. Other fat sources include stabilised rice bran and flaxseed, both of which are palatable to horses. Some commercial feed companies produce fat supplements that may be extruded or pelleted. Fat alone is devoid of balanced nutrients, so some commercially produced products include vitamin and mineral fortification as an added benefit.

8 Grootmaak van Kalwers voor Speen - Deel III: Implementering van Natuurlike Kalfgrootmaak Konsep - Dr Heinri Spangenberg, Lionel s Vet Vir meer inligting, skryf aan heinri@lionelsvet.co.za Soos reeds in hierdie reeks artikels bespreek is die korrekte grootmaak van vervangingsversies die finale fase waar die potensiaal van die toekomstige koei behoorlik vasgelê moet word. Hierdie artikel fokus op die implementering van n meer natuurlike kalfgrootmaakprogram of melkvoedingsfase om: - kuddeproduktiwiteit te verhoog d.m.v. verhoogde ontginning van genetiese potensiaal vir kwantitatiewe en kwalitatiewe eienskappe van vervangingverse; - gesonde vervangingsverse te hê as basis vir hoë produksies oor die volle leeftyd; - langslewendheid te bevorder en - dit te doen teen redelike behuisings-, arbeids-, veterinêre-, oorhoofse- en voedingskostes. Bestaande kalfgrootmaakpraktyke tot en met speen, is ontoereikend ten einde die toekomstige koei se genetiese produksie- en reproduksievermoëns optimaal te ontgin. Die algemene praktyk is dat kalwers se melkinname beperk word en dus onderwerp word aan onnatuurlike voedingstoestande of controlled starvation. Onthou dat vir elke 1g groei bokant 450g per dag voor speen, kan die vers 1 liter meer melk gedurende eerste laktasie produseer.

9 Tabel 1A Tabel 1B Week Melk* Pil DMI Massa kg Melk* Pil DMI Massa kg l/dag g/dag GDT tot Speen** GDT tot Speen*** l/dag g/dag GDT tot Speen** GDT tot Speen*** Geboorte * 125g Melkvervanger per liter water * 150g Melkvervanger per liter water ** 5 o C omgewingstemperatuur ** 5 o C omgewingstemperatuur *** 10 o C omgewingstemperatuur *** 10 o C omgewingstemperatuur Tabel 1A en 1B toon die verwagte kalfaanvangskorrelinname en gemiddelde daaglikse toename (GDT) vir kalwers wat op die konvensionele beheerde voeding van 4 liter melkvervanger per dag grootgemaak word met onderskeidelik 125g (1a) en 150g (1b) melkpoeier per liter water. Die verwagte resultate word vergelyk teen 5 o C en 10 o C omgewingstemperature en dit is duidelik dat lae omgewingstemperature GDT nadelig beïnvloed. Deur slegs die hoeveelheid melkpoeier te verhoog, veral tydens kouetoestande, kan daar alreeds n positiewe impak op GDT wees, alhoewel die effek groter op kalfgesondheid sal wees. Die 4 liter melk per dag voldoen dikwels nie eens aan onderhoudsbehoefte tydens kouetoestande nie. Die idee met hierdie stelsel is om geld te spaar op duur melkvervangers en die kalf te dwing om so vroeg moontlik n hoë inname van kalfaanvangskorrels te hê sodat rumenontwikkeling vinniger kan plaasvind. Dit is n bewese feit dat hoë inname van melk, veral varsmelk, rumenontwikkeling vertraag vanweë die hoë vetinhoud en gevolglike laer aanvangskorrelinname. Dit blyk egter uit die jongste navorsing dat die voordelige effek van hoër melkinname en dus meer melkvastestowwe en energie, veral tot op 6 weke ouderdom, meer voordelig is vir die kalf as bloot vroeë rumenontwikkeling. Beide voorspeense groei en gesondheid voor en na speen is beter by kalwers wat meer melk of melkvastestowwe ontvang het. Vanaf geboorte tot 6 weke ouderdom ontwikkel die rumen vanaf 25% tot 60% van die pensoppervlakte. Die jong kalf voor 6 weke oud benodig slegs n klein hoeveelheid korrek geformuleerde kalfaanvangskorrels vir optimale ontwikkeling van die rumen en rumenpapillae. Dit is egter van kardinale belang dat die korrekte kwaliteit melkvervanger gebruik word. Maak seker dat die proteïen van suiwel afkomstig is en nie plantaardig of dierlik nie, aangesien dit n groot invloed op groei het. Maak ook seker dat die vet gehomogeniseerd is om goeie vermenging te verkry.

10 Tabel 2A Tabel 2B Week Melk* Pil DMI Massa kg Melk* Pil DMI Massa kg l/dag g/dag GDT tot Speen** GDT tot Speen*** l/dag g/dag GDT tot Speen** GDT tot Speen*** Geboorte * 125g Melkvervanger per liter water * 150g Melkvervanger per liter water ** 5 o C omgewingstemperatuur ** 5 o C omgewingstemperatuur *** 10 o C omgewingstemperatuur *** 10 o C omgewingstemperatuur Tabel 2a en 2b toon die verwagte kalfaanvangskorrelinname en GDT vir kalwers wat melkvervanger ad lib ontvang met onderskeidelik 125g (2a) en 150g (2b) melkpoeier per liter water en teen 5 o C en 10 o C omgewingstemperature. Die enorme verskil in GDT teenoor kalwers wat slegs 4 liter per dag ontvang is duidelik, en is bloot die resultaat van verhoogde vastestofinname en dus energie d.m.v. melkvervanger en ongeag die laer inname van aanvangskorrels. Hierdie kalwers het ongeveer 400 MJ ME meer ingeneem oor die periode as die 4 liter groepe. Die liter melk per dag vanaf week 4 lyk onwerklik, maar onder natuurlike toestande met die kalf by haar ma sou die inname waarskynlik hoër gewees het. Dit is dus duidelik dat die hoë inname van aanvangskorrels soos in Tabel 1 nie noodwendig groei bevorder nie en veral nie wanneer gemiddelde of swak produkte gebruik word nie. Soos reeds gemeld word veralgemeen dat meer melk rumenontwikkeling onderdruk vanweë laer aanvangskorrelinname en gevolglike hoër speenskok en lae voerinnames na speen. Dit is nie die geval wanneer melk geleidelik verlaag word in die week of twee voor speen om aanvangskorrelinname te stimuleer en speenskok te verlig nie. Net soos in die geval van melkvervangers moet seker gemaak word dat kalfaanvangskorrels en groeikorrels korrek geformuleer en van baie goeie kwaliteit is om maksimale groei te verseker. n Stelsel van ad lib melkvoeding kan ingewikkeld en arbeidsintensief wees indien met bottels of emmers gevoer word. Hier is die oplossing om groepvoeding toe te pas. In teenstelling met die opvatting dat individuele voeding beter as groepvoeding is, toon studies dat kalwers in groepe dieselfde en selfs beter groei voor en na speen toon en dat behandelingskoste ook drasties laer is. Die rede hiervoor lê waarskynlik in die feit dat beeste tropdiere is en dat kalwers geborge is in n groep waar hulle meer spasie het en kan speel. Dit is egter krities dat baie klem op higiëne geplaas moet word met n groepstelsel. Maak seker die kalwers kry genoeg kolostrum binne die eerste 48 uur. Hou vir 7 dae in individuele hokkies waarna in groepies van 5 geplaas kan word indien gesond.

11 Tabel 3A Tabel 3B Week Melk* Pil DMI Massa kg Melk* Pil DMI Massa kg l/dag g/dag GDT tot Speen** GDT tot Speen*** l/dag g/dag GDT tot Speen** GDT tot Speen*** Geboorte * 125g Melkvervanger per liter water * 150g Melkvervanger per liter water ** 5 o C omgewingstemperatuur ** 5 o C omgewingstemperatuur *** 10 o C omgewingstemperatuur *** 10 o C omgewingstemperatuur Tabel 3A en 3B toon die verwagte kalfaanvangskorrelinname en GDT vir kalwers waar melkvervanger geleidelik verhoog word na 8 liter per dag en dan weer geleidelik afgeskaal word na 4 liter in die week voor speen om aanvangskorrelinname te stimuleer en speenskok te verlig. Hier word ook onderskeidelik 125g (3a) en 150g (3b) melkpoeier per liter water en teen 5 o C en 10 o C omgewingstemperature gevoer. Dit is n praktiese metode om meer melk te voer teen steeds 2 voedings per dag met baie goeie resultate i.t.v. GDT en gesondheid. n Kalfgrootmaakprogram soortgelyk aan die in Tabel 3a is in n kommersiële kudde in Arizona, VSA, vergelyk met die konvensionele 4 liter melkvervanger per dag program soos wat op die plaas toegpas was. Die verhoogde melkinname is ook gekomplimenteer met n spesiaal geformuleerde aanvangskorrel met die fokus op proteïenkwaliteit, aminosuurprofiel en die korrekte energiepakket i.t.v. konsentrasie, samestelling en roumateriale. Dit is ook belangrik om te noem dat die streek die 9de warmste aangetekende somer, met daaglikse maksimum temperature van meer as 47 o C, ondervind het tydens die proefperiode. Kalwers is op 35 dae geweeg en n monster geslag met volledige post mortems. Enkele belangrike afleidings uit die resultate: - die GDT van die proefgroep was 500 g per dag hoër as die kontrolegroep wat baie hoog is gegewe die normale lae GDT tot op 35 dae; - vetaansameling in die niere en om die ingewande was merkbaar meer by die proefgroep en n indikasie van hoër energie-inname (sien foto); - rumenontwikkeling en lengte van papillae was drasties beter vir die proefgroep en die resultaat van n hoër melkvoeding en beter geformuleerde aanvangskorrel; - rumen ph was vir die proefgroep en so laag as 5.0 vir die kontrolegroep wat op asidose dui en dus ook die rede is vir swakker papillae ontwikkeling by die kontrolegroep. - kalfmortaliteite was minder as 1% vir die proefgroep vergeleke met die 5% vir die kontrolegroep;

12 - slegs 5% kalfmorbiditeite en behandelings het by die proefgroep voorgekom vergeleke die 25% by die kontrolegroep. Konvensionele beperkte voeding program Meer Melk en Beter Aanvangskorrel Hierdie plaas voer tans 8 liter hoë kwaliteit melkvervanger per dag en het ook oorgeskakel na die spesiaal geformuleerde aanvangskorrel. Kalfmortaliteite, morbiditeite en behandelings het dramaties afgeneem terwyl geboortemassas meer as verdubbel en heuphoogtes van 99cm bereik word op 50 dae ouderdom. In n studie deur Onderstepoort Veterinêre Instituut waar die invloed van melkvolume en groepgrootte op GDT en gesondheid van Jerseykalwers ondersoek is, was die resultate ook baie gunstig vir die hoë volume melk groep (HV) vergeleke met die beperkte volume melk groep (BV). Die HV groep het gemiddeld 7 liter melk per dag (piek teen 7.6 liter) gedrink teenoor die BV groep se 4 liter. Enkele belangrike waarnemings uit die resultate: - HV groep toon betekenisvolle beter GDT en ondervind beter gesondheid voor en na speen wat aanduidend is dat speenskok nie n probleem was nie. Kalwers in al die groepe het dieselfde presteer na speen omdat aanvangskorrelinname by veral die HV gestimuleer is deur melkvolume te verlaag vanaf een week voor speen en ook slegs een melkvoeding per dag te gee; - HV kalwers in die groter groep het in verhouding tot GDT n baie hoë skofhoogte toename getoon wat moontlik toegskryf kan word aan verhoogde aktiwiteit met minder liggaamsvet by die kalwers; - die resultate toon ook dat groter groepe nie noodwendig n negatiewe impak op die groei en gesondheid van kalwers het wat buite gehuisves word nie. Die negatiewe effek van groter groepe is waarskynlik waar binnenshuise behuisingstelsels gebruik word en lugweginfeksies problematies is. Groter groepe met meer spasie het gewoonlik n ietwat swakker voeromsetverhouding (VOV) vanweë meer aktiwiteit. - die voer van groter volumes melk d.m.v. n fopspeen verlaag die insidensie van kalwers wat aan mekaar suip en wat gewoonlik n probleem is by groepvoeding; - die resultate uit hierdie studie toon dat melkvolume geen invloed op die voorkoms van diarree gehad het nie. Dit moet beklemtoon word dat higiëne die bepalende faktor vir die voorkoms van diarree is. - hierdie Jerseykalwers het teen 600 tot 650 (BV) en 700 tot 750 (HV) gegroei en vergelyk dus met Holsteinkalwers se groei.

13 n Meer natuurlike benadering van kalwervoeding lei beslis tot gesonder kalwers, laer tot geen mortaliteite en dus laer behandelingskostes. Groei en speenmassas is beter, verse kan vroeër gedek word en kalf dus vroeër, terwyl die koeie meer melk produseer vir hul volle en langer lewensduur. Die eindresultaat is n meer winsgewende suiwelbesigheid. Top Wenke - Dit moet deeglik verstaan word dat n kalf voor speen n baba is en dat net die beste kwaliteit voeding kan verseker dat sy tot haar volle produktiewe en reproduktiewe potensiaal sal ontwikkel. - Dit is baie belangrik om seker te maak dat die korrekte voeding en bestuur tydens die oorgangsfase, wat produserende koeie optimaal voorberei vir laktasie EN die ontwikkelende follikel en oösiet of eisel se genetiese potensiaal nie inhibeer nie, gevolg word. - Fokus op kolostrumvoeding tydens kritiese periode om die grondslag te lê vir gesonde kalwers en lae mortaliteite tot en met speen. - Maak seker jy weet wat jy voer. Koop die beste kwaliteit melkvervanger en aanvangskorrel beskikbaar om verlangde doelwitte te bereik. Produkte met uitstekende verteerbaarheid van voedingstowwe is krities om sukses te verseker. - Melkvervanger moet korrek gemeng word. Indien 125g melkpoeier opgemaak word tot 1 liter word 12.5% (125/1000) vastestowwe verskaf. Indien 125g melkpoeier by 1 liter water gevoeg word, word slegs 11.1% (125/1 125) vastestowwe verskaf. - Dit is baie belangrik dat nie meer as 150g melkpoeier per liter gevoer word nie om te verhoed dat die kalwers soutvergiftiging opdoen. - Konsekwente roetine van voedingsprosedures en aandag aan detail verminder stres en verseker gesonde kalwers wat goed groei. Verskaf die korrekte hoeveelheid melk op dieselfde tyd teen dieselfde temperatuur, korrek gemeng. - Meer as 4 liter melk of melkvervanger per dag veroorsaak NIE diarree nie. Diarree word eerder veroorsaak deur die patogeenlading in die onmiddelike omgewing en die graad van stres wat die kalf ondervind. - Voorsien deurgaans skoon drinkwater. Dit is nodig vir basiese metabolisme, rumenontwikkeling en voedingstofopname. Water veroorsaak NIE diarree nie, maar daarsonder word groei gestrem. - Sukses is gedoem sonder goeie higiëne. Moenie melk met antibiotikas, hoë SCC of wat besmet is met patogene wat oordraagbare siektes veroorsaak, voer nie. Doen moeite om patogene te verminder en kalfimmuniteit te verhoog. - Ontwerp kalfbehuising met die fokus op goeie ventilasie en lae humiditeit, voldoende lig en spasie, temperatuur en beddegoed vir maksimum gemak, lae stres en min vermorsing van energie deur kalf. - Stel doelwitte tov ouderdom en massa by speen, KI en eerste kalwing. Raadpleeg kundiges vir bystand met aanpassings van die huidige kalfgrootmaakstelsel om hierdie doelwitte te haal. - Kalwers moet geboortemassa op 60 dae minstens verdubbel. - Verse moet minstens 55% van volwassemassa op n KI ouderdom van 12 tot 14 maande bereik. - Verse moet minstens 85% van volwasse massa op kalfouderdom van 21 tot 23 maande bereik. - Voortdurende monitering en aandag aan detail verseker sukses met die grootmaak van vervangingsverse.

15 Teat Preparation Evidence of success Since its launch into the UK market late in 2016, the CID lines PureFoamer pre- milking teat preparation system has grown to become an important part of maintaining milk quality and efficient milking on many farms. In fact, by the end of 2017 there were over cows in the South West alone benefitting from the superior cleaning, disinfection and milking times that the system is able to bring. So with the mission of producing Cleaner, Faster Milk being realised, we thought it was time to look at the evidence and why it is a system to consider. But first, a reminder of why PureFoamer is important. What Happens Right Now on Farms? Strip, Dip, Wipe, Apply is the proven mantra that still works. We strip to check for issues and stimulate milk let-down. We then dip to clean and disinfect teats. This is followed by a thorough wipeoff to remove the dip residue along with muck and dirt and finally, we apply (attach) the clusters. Unfortunately, corners are cut and mistakes can be made in areas of this process. Dip This part is crucial as it represents the best chance of starting the dirt and muck removal process as well as disinfecting by removing pathogens. However, in many cases a product is used that does not contain the ingredients (surfactants or simply put, soaps) to remove debris, or the disinfectant included is not suitable to provide the rapid pre-milking kill needed. Additionally, products are often sprayed-on which is not optimal for total teat coverage due to the high chance of poor technique. So using this information, an iodine-based product that contains no surfactants and which is sprayed-on is sub-optimal due to the slow kill, lack of cleaning capability and chance of poor coverage. Wipe Linked to the potential issues above, wiping can be compromised by poor technique or unhygienic practice. Assuming a pre-dip has been used which does contain surfactants, a new paper towel for each cow should be used with careful attention paid to wiping the teat end clean. This area is often overlooked but is an important area to focus on before attaching the clusters.

16 The PureFoamer System Put very simply, the PureFoamer system enables a fast acting, lactic acid based product (Keno pure) to be applied to teats as a very high density dry foam. The surfactants included in Keno pure allows dirt, muck and debris to be removed extremely easily after 30 seconds with a paper towel, giving peace of mind that bacteria on the teats have been killed. Being an automatic system with a piped fed-line, foaming is straightforward, faster than applying a spray and with better coverage and less wastage. Results and Evidence from the Field Feedback from users of the PureFoamer system is positive. Typically, users report lower bactoscans, reduced cases of mastitis, improved teat condition, faster milking times with less teat damage and significantly reduced costs of product. Such anecdotal evidence is compelling and serves as excellent testimonial evidence for new users who are considering using the system. However, a recent Dairy Shield whole farm dairy audit carried out by Trevor Rogerson of UK distributor Pearce Dairy, included a deeper look at pre-milking teat hygiene and what the optimal protocol would look like for this individual farm. Dairy Shield Teat Preparation Results The audited farm had used many different teat preparation processes in the past, all with different results. Whilst some such as a dilute hypochlorite spray seemed to have been initially effective, deteriorating teat condition had halted the procedure. It is also worth remembering that seasonal conditions and weather patterns can also affect results. Using a device which measures the presence of ATP on a surface, indicating challenged cleaning processes and the resulting presence of contamination, including bacteria, we looked at the effect of different teat preparation techniques on teat cleanliness. In the study, four different preparations were used, each of which had been used before on the farm. In addition, Kenopure was demonstrated and recorded as a new alternative to the existing options. (Table 1.) Table 1.

17 Whilst the study was very limited and did not include all teat preparation options currently available in the UK, the results that were recorded showed a considerable advantage to the PureFoamer system with a 99.6% drop in contamination after using Keno pure. In addition, in all cases apart from when Keno pure was applied, there was visible contamination to teats before attaching clusters and in the processes, which included hypochlorite spray and alcohol-based wipes, teat skin condition was observed to be dry post-application. Further results will be recorded as CID LINES distributors continue auditing on customers farms and we hope to be able to report on similar results as the data grows and the evidence becomes available. Installing a PureFoamer System Installation of the PureFoamer system into dairies could not be simpler. Utilising the tried and tested Cotswold SupaSpray pump, the only connection needed is a feed into the vacuum line. This enables the uptake of Keno pure from the drum and the feed of Keno pure to the PureFoamer foaming head cup. There are no electrical connections or compressed air feeds needed, meaning that as well as being very simple to install, there are few parts to fail and a very high level of reliability. The PureFoamer system is available exclusively through all UK distributors. Start-Up offers available including everything needed to start delivering a new level of teat preparation on your farm.
