In present investigation, a total 440 quarter milk samples of 110 buffaloes were screened for subclinical mastitis (SCM).

Age-wise occurrence was highest in the age group of 6-8 years and lowest in the age group of above 12 years both animal and quarter basis. The occurrence of SCM both animal and quarter wise, in relation to lactation number was observed highest during fifth lactation and lowest in the first lactations and; in relation to lactation stage the occurrence was found highest in mid lactation, followed by early and least during late lactations on quarter as well as animal basis. Based on quarter disposition, occurrence of SCM was highest in right hind quarter followed by right fore. Buffaloes with milk production of more than 8 liters/day were affected more with SCM.
