Effect of Protein Supplementation on Growth Performance in Female Goats and Sheep under Grazing Condition

Abstract: The experiment was conducted to determine the effect of protein supplementation on growth performance in female goats and sheep. Ten does and six ewes aged about 15 months and weighing on average, 13.9 and 14.4 kg respectively were studied in this experiment. Animals were allocated to two feeding regimes [low protein (LP), 168g and high protein (HP), 208g per kg DM] in a randomized block design according to live weight. HP diet did not significantly (p>0.05) increase live weight gain (33.0 vs. 25.2 g/d) in goats. In contrast, sheep received the HP diet significantly (p<0.05, p<0.01) improved DM intake (509.0 vs. 425.9 g/d) and live weight gain (36.6 vs. 10.7 g/d) compared to those given the LP diet. These results indicate that supplementary feeding of high protein diet (208g CP per kg DM) significantly increased growth performance of sheep under grazing condition.
