Abstract
An experiment was conducted for the first time in Iraq to examine the growth performance, carcass characteristics and economic return of diets containing locally grown full-fat soybean (FFSB) in broiler chickens. Five diets were prepared containing 10, 20 and 30% of roasted (RFFSB), 20% unroasted FFSB or control diet containing conventional soybean meal (SBM). Each diet was fed to five replicates of 30 chicks each. For the period from 0 to 21 and 0 to 42 days of age, the birds that were fed 10% RFFSB were significantly superior in weight gain to other experimental birds. However, no significant differences were found between dietary treatments for live body weight at 49 days and weight gain at the period from 0 to 49 days of age. Feeding chickens 10% roasted FFSB resulted in better feed conversion ratio and production index compared to those fed 20, 30% roasted or 20% unroasted FFSB. Results revealed no significant differences in carcass characteristics between the birds fed the five experimental diets. It was concluded that the inclusion of 25% RFFSB in the starter and up to 35% in the finisher of broiler diets instead of SBM would improve performance. Economically each replacement has 100% better economic return to the producer than the conventional soybean meal based diet.
