TAKE EXTRA PRECAUTIONS AGAINST SUMMER MASTITIS
August temperatures have resulted in increased fly populations in many parts of the UK and dairy farmers are being advised to take extra precautions to guard against summer mastitis in heifers. Alison Clark, from dairy hygiene specialists Progiene, says greater vigilance will be essential, particularly during hot weather, as early intervention is all important with a disease that can otherwise result in a lost quarter, or worse. In high risk situations, she recommends use of an external teat sealant for dry cows and in-calf heifers, to create a physical barrier to prevent the bacteria transmitted by flies entering the udder. “Summer mastitis, or ‘August Bag’, is a bacterial infection of the udder, with the bacteria being spread by biting flies, like the head fly,” she explains. “Where possible, it is best to avoid keeping heifers in areas where flies are most likely to be a problem, and steps should be taken to control flies. However, with this summer’s heat resulting in higher and more persistent populations, it may be advisable to take additional precautions. “Applying Uddershield Dry to the teats of heifers creates a physical external barrier, closing off the teat canal to the ingress of any bacteria, whatever the fly populations. If used strategically, when risks are highest and heifers are most vulnerable, this is an effective complementary action alongside the other precautions taken to minimise risks.”
Uddershield Dry, previously marketed by Progiene as T-Hexx Dry, is applied like a teat dip following thorough cleaning and disinfection of the teats. The application dries in five to ten minutes to form a distinctive blue physical shield over the teat end. The barrier is resistant to water, urine and manure and will remain effective for up to seven days. “Optimum timing of application can be determined through extra vigilance of the heifer groups,” Ms Clark adds. “If fly populations are excessive, with heifers being especially agitated, then it may be advisable to apply Uddershield Dry. “All being well, this is carried out before any problems arise, but the process of applying the barrier is an ideal opportunity to check udders closely and spot any early signs of infection.
“If there are any indications of heat or swelling, consult your vet as this may be the early stages of summer mastitis. The condition will be treatable, with no long term effects, if caught early.”
In conclusion, Ms Clark stresses the importance of vigilance and precautionary actions, particularly with livestock that represent the future of the dairy herd.
“In most cases, dairy farms will have invested in the breeding and rearing of replacement heifers for at least two years, with their entry into the milking herd much anticipated.
“Having one calve down three-quartered, as a result of summer mastitis, would be a severe blow and a significant loss of future performance and profitability.
“Taking the extra step of an external teat sealant, when the risks are high, could be a very cost-effective addition to the herd’s mastitis control plans.”
