Mastitis: The Canadian Perspective

摘要

Staph. aureus is present in nearly all Canadian dairy farms, while Strep, agalactiae may be at the brink of extinction in Canada. Reducing Staph. aureus is an important tool to reduce BMSCC. Management on most Canadian dairy farms is good, but there is still quite some room for improvement. Staph. aureus is the most frequently isolated bacteria in clinical mastitis cases. The NMC has a recommended mastitis plan with 10 areas of attention (NMC, 2004) that is generally considered as the standard for mastitis management. A number of studies in Canada investigated management practices on dairy farms (Spicer et al., 1994; Sargeant et al., 1997; VanLeeuwen and Keefe, 1998). However, these studies did not focus much on mastitis management. Therefore, compliance to these 10 management areas by Canadian dairy farms is unknown.
