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.

Abstract

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 and 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 and T3, rectal temperature was also significantly higher in T1 (P>0.05). Thermal heat index was also calculated and reported in this study.
