Abstract:
The present study was planned to evaluate the effect of Multi-nutrient block (MBs) and Tanniferous Multi-nutrient block (TMBs) on reproductive performance of Murrah buffalo heifers. A total of 21 Murrah buffalo heifers were selected and divided into three experimental groups (T₁, T₂ and T₃) having seven heifers in each group, based on body weight (247±2.29 kg) and age (40±04 months). Control (T₁) group was fed basal diet, comprising of wheat straw (ad lib), green fodder and concentrate to ful fill nutrient requirement of animals (ICAR, 2013). T₂ group was fed basal diet with only 60% of concentrate mixture of T₁ group supplemented with MBs (ad lib). T₃ group was fed basal diet with only 60% of concentrate mixture of T₁ group supplemented with TMBs (ad lib). Progesterone and estradiol concentration increased between intervals in all groups. MBs and TMBs supplemented buffalo heifer exhibited highest percentage of estrus during trial while highest conception rate was found in T₃ group. Based on the findings of the present study, it is concluded that MB’s and TMBs supplementation lead to equal reproductive performance Thus MBs and TMBs can safely replace 40% concentrate mixture which improve reproductive performance of Murrah buffalo heifers.
