Abstract
The study was conducted to evaluate the effects of dietary replacement of graded levels of pigeon pea (cajanus cajan) seed meal for soybean seed meal on performance of Cobb 500 broiler chicks on feed intake, growth performance and carcass traits in Dilla University, southern, Ethiopia. One hundred eighty (180) unsexed Cobb500 broilers day old chicks were randomly assigned to five treatment diets with three replications in a completely randomized design. Experimental diets: were formulated in such a way that [T1, T2, T3, T4 and T5 to replace 0%, 25%, 50% ,75% and 100% of soya bean seed meal by pigeon pea seed meal respectively for both starter and Finisher diets.. Data collection of the feeding trial started after an adaptation period of the chicks to the experimental pens and diets for three days. Final body weight gain, average daily body weight gain were not significantly different (P>0.05) in all treatments. But, carcass characteristics did not vary (P>0.05) across treatments. Mortality was not recorded in all treatments. Cost of feed per body weight gain (gram) declined as the replacement level of pigeon pea seed meal increased in treatment diets but net profit increased with increasing level of pigeon pea seed meal. Thus, it was concluded that replacing soybean seed meal by pigeon pea seed meal as unconventional protein source in starter and finisher broilers diets up to 100% is economically feasible and more profitable and nutritionally adequate without adverse effects on the performance of Cobb500 broiler chicks.
