Effect of I/M Se and Vit E administration combined with cooler hours feeding regime on milk production in buffaloes in hot-humid climate of Bundelkhand region

A farm experiment was carried out to assess the effect of vitamin E and selenium I/M injection on performance of buffaloes during heat stress period in Tikamgarh district of Bundelkhand Agroclimatic zone. A total of 24 animals (80±10 days postpartum and 650±25 kg body weight) were randomly divided in to 3 treatments with 8 buffaloes in each group in a completely randomized design and received a balance feed as per BIS 1992 (Type-II). T₂ group was injected with 10 ml from a solution of vitamin E and selenium after interval of 10 days and T₃ group was injected I/M with 10 ml from solution of vitamin E and selenium after interval of 15 days. Dry matter intake and milk yield and milk composition in T₂ & T₃ was observed to be higher (P>0.05) than control group. The respiration rate and pulse rate were observed to be significantly higher (P>0.05) in T₁ group than T₂ & T₃, rectal temperature was also significantly higher in T1 (P>0.05). Thermal heat index was also calculated and reported in this study.
