Out of the positive samples, 12.2% were having infection in single, while, 2.0% were having infection in both halves of the udder. Beetle breed was infected at the highest rate i.e. 22.54% following desi breed i.e. 10.40% and teddy breed i.e. 8.80%, respectively. Prevalence of mastitis increased with increase in number of parity i.e. 8.5% up to 2 nd parity and 19.76% up to 3 rd parity. Bacteriological profile showed that Staphylococcus aureus was the most common pathogen i.e. 51.43% isolated.
