Globally, bovine mastitis is the most prevalent inflammatory disease of mammary gland that causes economic loss to the dairy industry. It is vital to study the risk factors associated with mastitis in order to design suitable prevention and control strategies. With this objective a survey was conducted among dairy farmers (n=300) in Tamil Nadu to identify the host specific risk factors associated with clinical mastitis. Species (OR=1.88, CI 95%= 1.15- 3.08, p=0.01), breed (OR=0.22, CI 95%= 0.12- 0.41, p<0.001), parity of cow (OR=0.69, CI 95%= 0.51- 0.93, p=0.02), lactation stage (OR=0.55, CI 95%= 0.40- 0.74, p<0.001) and milk yield (OR=2.77, CI 95%= 1.95- 3.93, p<0.001) were identified as significant risk factor for clinical mastitis in lactating dairy cows in the study area. Understanding these factors assists dairy farmers in mitigating clinical mastitis in their herds.

Keywords    Mastitis, risk factors, crossbreds, parity, stage of lactation, milk yield.
