Twenty seven entire lambs of Sudan desert sheep were used to evaluate the effect of using different level of sesame cake meal (SCM) in a fattening experiment which extended for fifty days. Experimental animals were fed iso-caloric and iso-nitrogenous diets containing two sources of protein: groundnut cake (treatment A) and sesame cake at 15% level (treatment B) and at 20% level (treatment C). Significant (≤ 0.05) differences were observed only in Daily weight gain, Feed conversion ratio and heart weight. In these traits treatment A and C were superior to treatment B, the three treatments record 0.166±0. 0.179±0.03 and 0.143±0.01b g/d, 6.87±2.4, 7.65±1.1 and 9.02±1.7 DMI/kg gain and 0.25±0.00, 0.26 ±0.02, 0.30±0.00 kg for the traits respectively. It was concluded that the addition of sesame cake up to 20% lead to satisfactory feedlot performance and carcass yield.
