Effect of feeding brewery dried grain (BDG) with enzyme supplement on the performance of broilers

Performance, carcass traits and organ weights were evaluated in 150 commercial broiler chickens from 1st day to 6 week of age. Two basal diets were formulated containing maize, groundnut cake, fish meal and wheat bran with 22.8% CP and 2800 KCal ME/Kg diet at starter phase (0–3 weeks) and 19.9% CP and 2900 Kcal ME/Kg diet at finisher phase (4–6 weeks). The broiler chicks of 5 groups were fed 5 diets where 1^st diet was control and other four diets contained 5 and 10% brewery dried grain (BDG) with (@0.75 g/Kg feed) or without enzyme supplement Kemzyme HF (a cellulase-complex with β-glucanase). Body weight and feed efficiency of broilers fed diet incorporated with 5% BDG and Kemzyme-HF were comparable to that of control diet. Carcass traits did not show significant difference among the treatments except drumstick weight, which was significantly (P<0.05) higher in chicks fed 5 and 10% BDG with or without Kemzyme. Organ weights also showed similar response as that of carcass traits barring relative weight of heart, which was significantly (P<0.05) higher in chicks fed 5 and 10% BDG with Kemzyme compared to control group. Incorporation of 5% BDG with kemzyme @ 0.75 g/Kg feed was suggested for economic production.
