Mastitis in dairy cows.

No disease in dairy cattle is affected more by total management than is the level of mastitis. The maintenance of a sanitary, comfortable environment and the execution of proper milking procedures used with properly functioning milking machines are all important in reducing and maintaining a low level of new infection in a herd. When these items are executed properly, along with a successful dry-cow treatment program, mastitis can be maintained at a level that is no longer of economic importance.
