PERFORMANCE OF BROILER STARTER FED DIETS CONTAINING SOYA BEAN RESIDUE SBR SUPPLEMENTED WITH ENZYME

Abstract

Feeding trial was conducted to determine the potentials of soya bean residue supplemented with exogenous enzyme at starter phase (0-28 days). A total of three hundred and sixty (360) day old Cobb 500 broiler chicks were randomly allocated to four (4) dietary treatments containing 10% soya bean residue meal supplemented with exogenous enzyme (En-lay) with different levels of supplementation designated as 0, 20, 25 and 30g. Each treatment were replicated thrice with thirty (30) birds per replica in randomize complete block design (RCBD). All routine husbandry management practices were adhered strictly and the experiment lasted for 28 days. Data were generated for feed intake, live weight gain, and feed conversion ratio, while cost benefit analysis were computed according to prices of feed ingredients procured during the experimental period and were subjected to Analysis of Variance (ANOVA). Significant difference between means were separated using Duncan’s multiple range test (DMRT). Growth performance results showed no significant (P>0.05) differences among all the treatment groups. However, broiler chicks fed SBR supplemented with 25g/100kg En-lay showed better performance (1.53) in terms feed conversion ratio (FCR) with least feed cost (N340.73) per kg gain. Therefore, SBR supplemented with En-lay have positive effect on performance and can be used in diets for broiler starter chickens as source of protein.
