Abstract

Quarter samples for culture were collected from 120 beef cows in early, mid, and late lactation to assess prevalence of mastitis pathogens and effects of mastitis on calf weight gain. In early, mid and late lactation respectively, 25.8, 29.2, and 54.4% of cows and 13.1, 14.9, and 27.5% of quarters were infected.
