Multistage random sampling technique was adopted to choose the final 40 households having cows affected from a population of total 110 dairy cows during the period between January and March 2013. The association of literacy of farmers, family size, lactation numbers and season with the incidence of mastitis was highly significant(P<0.01) and the association of breed, milk yield, stage of lactation, udder morphology, management practices, type of floor, nail cutting habit of milk-man and previous occurrence of mastitis with the current incidence of mastitis was significant(P<0.05). The mastitis incidence was more prevalent in fifth lactation during rainy season, in crossbred Holstein Friesian, in higher average daily milk yield of more than 15 litres, during early stage of lactation (53.65%), in cows having pendulous udder (60.00%) and previous occurrence of mastitis, and in cows kept on muddy soil floor.enVeterinary ScienceArticle
