Mastitis is a very costly problem causing the farmer financial loss because of: milk lost through decreased production, discarded milk, medicine cost, animals culled from the herd, and veterinarian fees. Mastitis is a luxury the farmer cannot afford, yet there are many that feel it is something they must live with. There are three areas of concern when confronted with a mastitis problem: (a) management of the herd, (b) adequate milking system, properly installed, and (c) sub-clinical or infectious mastitis. To be successful in correcting a mastitis problem requires use of all resources. A team approach is used and the team consists of the dairy plant fieldman and laboratory, milking machine serviceman, area extension dairy specialist, veterinarian and the farmer who desires to correct the problem. Every person on this team has an important part to play in solving the problem. The result of solving the problem is a financial gain for the farmer.
