The results snowed no significant difference among treatments neither in term of weight gain per week nor total weight gain during 7 weeks of experiment. Weight gain per chick during 7 weeks period was averaged at 1.667, 1.667, 1.673, and 1.575 kgs. for broilers raised with 0,5,10,20 and 40% PRSM feeds respectively. It was found that feed conversion values pertaining to 40% PRSM treatment was significantly higher than 20% PRSM treatment, and these two treatments were also significantly higher at 1% level than 10, 5 and 0% PRSM treatments. Necropsy finding snowed no lesion related to the use of PRSM in feeding and no hydrocyanic acid was found in the tissue samples by means of colorimetric metnod. This experiment snowed that up to 40% of PRSM could be used in broiler feed witnout causing any detrimental effects or significant difference in weight gain. Justification for utilization of PRSM in broiler feed could then be determined in terms of economics that was the comparative cost of feeds required to produce a kilogram of meat. In these particular circumstances, feed with 10% PRSM was the most economical one
