Abstract

Information related to mastitis risk factors is useful for the design and implementation of clinical mastitis (CM) control programs. The first objective of our study was to model the risk of CM under Brazilian conditions, using cow-specific risk factors. Our second objective was to explore which...

Abstract

Daily examination of the foremilk of 134 primiparae in several herds for the first week of lactation and regularly throughout the lactation period revealed that in 6.3% of all quarters organisms were persistently excreted beyond the first week. Of 143 primiparae observed throughout lactation, 37.7% ...
