Abstract
Mastitis in heifers is not uncommon. During the last 20 years, numerous investigations have described the nature of mastitis in heifers (Fox, 2009). Coagulase-negative staphylococci (CNS) are the most prevalent cause of intramammary infections (IMI) in heifers around calving, but Staphylococcus aureus should not be ignored as it is also prevalent, contagious, and more likely to persist into lactation. Some studies have shown a negative impact of an elevated early lactation somatic cell count (SCC) on subsequent test-day SCC, milk production and survival in heifers (De Vleigher et al, 2004-2005). The impact should vary according to the pathogen causing the IMI. The objective of this study was to determine the effect of an IMI caused by CNS or S. aureus diagnosed during the first month of lactation in heifers on SCC, milk production, and culling risk during the first lactation.
