Ahles Serving the dairy industry by providing prevention, treatment, and promoting efficiency – since 1958 Mammillitits Local Dairy Meetings Bovine Ulcerative Mammillitis is a condition seen most commonly in fresh heifers during the winter months. It is caused by a herpes virus and is difficult both to prevent and treat. Heifers with edematous udders around freshening are at greater risk for mammillitis. Once this virus is present on a farm it is very difficult to eliminate. Some closed dairy herds may be free of the mammillitis virus, and these herds could be susceptible to larger outbreaks in the event of infection, even in older cows. Midwest Manure Summit – Feb. 26-27 Green Bay, WI Technologies and strategies used to handle and process manure. Register online at www.midwestmanure.com Prevention of mammillitis is similar to mastitis- clean animals, clean environments, good milking procedures, and healthy udders/teats. Treating udder edema in heifers early with diuretics, topicals, or steroids is important. Isolating affected animals is important as this is contagious, and iodine based teat dips are recommended to kill the virus. Herpes Mammillitis usually starts out as a blister or boil on the teat, breaks open to become an ulcer, and spreads over the teat and udder. The lesion or discolored area will die, become leathery and eventually peel and fall off. This may be a small or very large area and severe cases can lead to gangrenous mastitis and loss of entire quarters. Affected teats are painful, often difficult to milk out, and easily lead to mastitis. There is no actual treatment for this disease, so therapy is focused on supportive care such as topical emollients and teat bandages. In many cases, it may be necessary to consider culling affected animals.
