Abstract

This study was conducted to evaluate the utilization of cassoya-based diets, (40:60 mixture of cassava root meal and full-fat soybean) supplemented with multi-enzyme for broiler chickens on haematological, biochemical and carcass and organ characteristics. The experiment involved the use of 300 day-old ROSS 308 broiler chickens. The birds were allotted to 6 dietary treatments (T) for 42 days with 50 birds per treatment and 5 replicates, in a 3x2 factorial arrangement, T1 – T3 contained cassoya at 0, 50 and 100 % without enzyme while T4 - T6 had protease enzyme 10 g/tonne. Data on carcass characteristics were collected and subjected to Analysis of Variance in a Completely Randomized Design. Birds on enzyme supplemented diets recorded the highest values (p<0.05) for carcass weight and gut morphology. The mean values for final live weight ranged from 1112.20 g to 1738.60 g, highest values were obtained in birds fed 0 % and 50 % cassoya with enzyme supplementation while the least was obtained in birds fed 100 % cassoya without enzyme supplementation. Cassoya diet at 50 % level of inclusion with multi-enzyme supplementation in broiler starter and finisher diets is recommended for improved performance.
