Economics of mastitis control.

Mastitis control is a continuing process that should be applied to all herds without relaxation. Programs likely to achieve widespread adoption must emphasize control of all pathogens rather than eradication of specific pathogens. Although none of the methods available at this time provide complete protection, the devastating losses from mastitis can be minimized with current technology in the vast majority of dairy herds. A control method similar to the Five-Point Program of Mastitis Control just discussed has the greatest utility. The program is not dependent upon examination by specialists, can be applied to any herd, is effective against common pathogens, results in a profit of $3 to $5 for each dollar invested, reduces clinical mastitis, and is flexible to permit refinement as additional knowledge becomes available. Failure of the Five-Point Plan of Mastitis Control in a small number of herds that seemingly are well managed is often due to failure of the farmer to apply the methods properly. In some instances, the farmer may perceive that he is following the full control program when, in reality, he is following only a part of the program. Overlapping and complementary components are of greatest value. Control methods that aim at a particular organism are highly dependent upon advisory personnel and supporting laboratories and have little chance of reaching a majority of dairy herds. Not only will the conscientious application of the Five-Point Program of Mastitis Control return 300 to 500 per cent on investment, but the quality of milk ultimately reaching the consuming public will be improved and the dairy farmer will, in effect, be helping to protect his present and future market. Herds with a high level of infection obviously stand to realize greater increase in profits from initiating a mastitis control program. This is because herds with a low level are already reaping the benefits. Nevertheless, implementing or continuing an effective mastitis control program is a wise and prudent decision for all dairy farmers.
