Growth performance, blood profile and nutrients digestibility of broiler chickens fed Enterolobium cyclocarpum seed based diets with or without supplemental exogenous enzyme

摘要

A 63-day study using 150, seven day old broiler chicks was conducted to evaluate the effect of Enterolobium cyclocarpum seed meal (ECSM) based diets on growth performance, blood profde and nutrient digestibility in six dietary treatments containing 0,5 and 10% ECSM with or without enzyme supplementation using 2x3 factorial layout in a completely randomized design. Results showed that the main and interaction effects of enzyme supplementation and inclusion level of ECSM did not significantly (p>0.05)influence the growth parameters studied. Enzyme supplementation significantly (p0.05) on the haematological indices of broiler chicken except the white blood cell and lymphocytes values. The white blood cell and lymphocytes values increased across the dietary treatments as the ECSM supplemented with or without enzyme increased. Main and interactive effects of enzyme supplementation and ECSM inclusion levels significantly (p<0.05) affected the nutrient digestibility. Birds feddiet supplemented with enzyme and those fed 5% ECSM based diet had better nutrient digestibility values. The study concluded that ECSM could be used up to 5% supplemented with enzymes in broiler chickens ' diet without any adverse effect on broiler's performance.
