Thirty-five Yankasa rams about 11/2 years old and of average weight 27kg were randomly assigned to five experimental diets which were (l) a control with 60% concentrate, diets 2 and 3 and 4 and 5 had the corn replaced by 20% and 40°/o brewers' dried grain (BDG) and palm kernel meal (PKM) respectively. All animals were individually fed the diets for the 70 days of the study. Average daily gain (ADC) was significantly (P 0.05) depressed only at the 40% BDC, level when compared with that of the control. Dressing percentage and percentage yield of wholesale cuts were not affected by the treatments. Nitrogen digestibility was significantly (P 0.05) depressed at the 40% BDG level. Based on the total performance and cost considerations, it was economical to use 20% BDG and up to 40% PKM in ram fattening diets.
