From 2 to 6 weeks old 180 broilers were in 6 groups and given a maize and extracted soyabeans (45%) control diet (T1), or the control diet with extracted soyabeans partially replaced with sesame oilmeal 13.70 (T2), 24.55 (T3), 25.64 (T4), 26.73 (T5) or 28.20% (T6). All diets contained adequate lysine, methionine and cystine. From 2 to 4 weeks old T6 had the highest weight gain, significantly different only from the control (T1), and from 4 to 6 weeks group T4 had the highest weight gain, significantly different from all groups except T6. Feed efficiency and performance index were significantly better in group T6 at both 2 to 4 and 4 to 6 weeks compared with controls. Protein and energy retentions were similar in groups T2, T3, T4 and T6. T5 had significantly lower body weight gain, gain to feed ratio and protein efficiency ratio from 4 to 6 weeks, suggesting poor nutrient utilization in this period. Estimated cost of feed was lowest in group T6. A combination of extracted soyabeans 23.5% and sesame oilmeal 28.2% was the most economical and gave maximum performance in broilers.
