Abstract: Two experiments were carried out to investigate the effect of roasted Pigeonpea Seed Meal (PSM) on growth performance of broiler birds. Two hundred and forty day-old commercial unsexed broiler chicks (Anak strain) were used in experiment 1, while 168 four-week old broiler birds from experiment 1 were used in experiment 2. Birds in experiments 1 and 2 were divided into 6 groups. Experiment 1 birds were randomly assigned to six isoenergetic and isonitrogenous broiler starter diets containing 0, 6.5, 13.0, 19.5, 26.0 and 32.5% roasted PSM. Experiment 2 birds were also randomly assigned to 6 isoenergetic and isonitrogenous broiler finisher diets containing 0, 5.5, 10.5, 16.0, 21.5 and 27.0% roasted PSM. Parameters considered were weight gain, feed intake, feed conversion ratio, protein efficiency ratio, dressed carcass weight and carcass dressing percent. Results (Experiment 1) showed that there were significant differences (p<0.05) among treatments in average daily weight gain, average daily feed intake and feed conversion ratio. Feed intake, weight gain and efficiency of feed utilization declined at the 32.5% level of roasted PSM inclusion. However, there were no significant differences (p>0.05) among treatments in all the parameters considered in experiment 2. The results showed conclusively that roasted PSM can be included in broiler starter and finisher diets at 26% and 27% levels, respectively without any adverse effect on broiler birds.
