Abstract

The present study was aimed to know the effect of dietary energy levels on growth and carcass characteristics in Black Bengal goats. Nine female Black Bengal goats were divided into three groups having three goats in each group. Three iso-nitrogenous diets containing three levels of metabolizable energy (9.17, 10.40 and 11.63 MJ/kg DM) were randomly assigned to three groups. Goats were stall fed and slaughtered after 150 days of trial. Results showed that live weight gain was higher (28.3 ± 1.7 g/day) in high energy fed goats than others. There were no significant differences on total and daily average dry matter intake in different groups of goats. Body length was significantly higher in high energy fed group than others. Carcass weight and dressing percentage were also higher (p<0.05) in high energy fed goats. Caul fat and gut fill weight differed significantly (p<0.05) among the treatment groups, and higher caul fat and lower gut fill were obtained in high energy fed goats than others. In conclusion, high energy diet enhanced the growth, dressing percentage and carcass gain of female goats.
