Influence of concentrate supplementation on production and reproduction performance of female Black Bengal goat

Abstract

A total sixteen female Black Bengal goats (BBG) considering average live weight were randomly divided into four equal treatments to study the effect of different level of concentrates supplementation on production and reproduction performance of BBG. The animals were assigned to adlibitum green grass and supplemented with different levels of concentrates at 150, 200, 250 and 300 g respectively. Live weight gain, Dry matter (DM) intake, Crude protein (CP) intake were increased significantly (p less than 0.01) with concentrate supplementation. Feed conversion ratio (FCR) and protein conversion ratio (PCR) were not significant on level of concentrate. The value of services per conception, birth weight of kids and growth rate of kids showed a positive effect on level of concentrate supplementation but not significant. Average daily milk yield of doe were increased significantly (p less than 0.01). Supplementation of concentrate mixture with 300 gm could be beneficial for BBG in Bangladesh condition.
