Biosecurity for mammary diseases in dairy cattle.
As US dairies grow ever larger and obtain replacement animals from a wide geographical area, biosecurity will loom ever more important as a means of controlling mammary disease. To prevent costly outbreaks of contagious mastitis, introduced animals must be screened for contagious IMI before the resident herd is exposed to them. Screening programs must be instituted to detect the appearance of contagious IMI as soon as possible after introduction has occurred. Most importantly, 40 years of knowledge regarding the on-farm control of contagious mastitis (now known as with-in-herd biosecurity) must be dusted off and implemented with renewed vigor to prevent the rampant spread of contagious mastitis.
