Bacterial flora on the mammary gland skin of sows and in their colostrum

Abstract

Mammary-gland skin swabs and milk samples were analysed bacteriologically. All skin samples were positive, with 5.2 isolates on average, Staphylococcaceae being the dominant organisms. In 20.8% of milk samples, no bacteria were detected. Two isolates on average, mainly Staphylococcaceae and Streptococcaceae, were isolated from the positive milk samples.
