Performances of Murrah cross buffalo under coastal climate of Goa

Twenty Murrah cross buffaloes were housed in semi-open RCC shed with east-west orientation having GI sheet roof. Buffaloes were maintained in semi intensive system of management. Two male and four female calves were born with a sex ratio of 1:2 during this period. Highest daily milk yield of 9.279 ± 0.034 lit was recorded in the month March with an overall mean value of 7.279 ± 0.081 lit/head/day. ANOVA indicated that month had highly significant (P < 0.01) effect on average daily milk yield. Multiple regression analysis revealed that daily milk yield was reduced by 782 ml and 285 ml per°C rise of air temperature and per % increase of relative humidity. So effect of air temperature was much higher than that of relative humidity. During this period only one buffalo died due to postoperative septicemia.
