Assessment and management of pain in dairy cows with clinical mastitis. (Special Issue: Mastitis in dairy cows.)

摘要

It is clear that clinical mastitis has severe detrimental effects on the animal and negative economic impacts for dairy producers. However, pain associated with clinical mastitis, generally, is not measured and not treated. Attention to behavioral and physiologic indicators should be used to monitor animal health. New technologies may allow dairy producers to identify clinical mastitis in its very early stages, or even before clinical changes occur. Furthermore, automated measures of activity, such as step counts and lying time, show promise as predictors of clinical problems. These new technologies, in addition to other automated measures, have the potential for improving the screening methods for preclinical mastitis and accurately predicting the onset of a clinical mastitis event. With this opportunity for very early detection of infection, there is a potential for early intervention with NSAID therapy, which may allow for maximum efficacy from its use. Despite which specific NSAID is used, it is clear that the benefits on temperature, rumen function, SCC, milk production, behavior, and pain sensitivity in animals during mastitis indicate that this therapy has a role throughout the dairy industry. As the health and well-being of dairy cattle continue to be scrutinized by consumer groups, it is essential that the alleviation of any perceived pain or discomfort associated with clinical mastitis should be addressed.
