SUMMARY

In a feedlot experiment three diets containing low molasses (LM), high molasses (HM) or high sorghum (HS) were offered to three groups of Sudan Desert lambs (22 animals each) from an average of 25.4 Kg liveweight to 40.7 Kg slaughter weight. The mean daily liveweight gain for group LM, HM and HS was found 196, 161 and 179 g respectively. Significant differences (P < 0.05) were observed among the treatments in bone and fat percentages of the carcass. ,2 Statistical analysis of the pooled data from the cune nt and previous trials at this institution showed a high correlation of energy and protein intake with liveweight gain. Using regression analysis the extrapolated maintenance energy requirement (499 KJ. Kg’ 035 ) of the Sudan Desert lambs was found consistent with the reported literature.
