Of the total dairy cows examined (N=387), 36.69% (n=142) of them were found to be positive for either clinical or sub clinical mastitis. Clinical and sub clinical mastitis were found to be 7.75% (n=30) and 28.94% (n=112), respectively. Factors significantly associated with mastitis were, lactation stage (χ 2 = 38.85, P 0.05).
