Performance of Yankasa RAM lambs fed graded levels of RMW and SBMR combination in the semi-arid zone, Nigeria

This experiment was conducted at Bayero University Kano, to determine the performance of Yankasa ram lambs fed complete diet containing graded levels of SBMR and RMW at 5, 10, 15 and 20% representing treatments B, C, D and E, respectively. Treatment A served as the control with 0% inclusion of both SBMR and RMW. Twenty entire males Yankasa ram lambs with an average weight of 14.3 ±0.03kg were used for the study. Results obtained revealed that incorporation of RMW and SBMR in the diets of growing Yankasa ram lambs up to 20% gave impressive output. Although significant differences were not recorded (P > 0.05) between all the treatments in respect of average daily gain (ADG), diet C (10% inclusion) recorded the highest mean. The Dry matter, Crude fibre and Crude protein digestibility significantly (P < 0.05) increased gradually up to 20% inclusion level from the control diet (0% inclusion). Similarly cost of production was significantly (P < 0.05) lower for diet E (20% inclusion). It is concluded that feeding combination of RMW and SBMR to growing Yankasa ram lambs up to 20% inclusion level improved performance and reduced cost of production.
