An experiment of six weeks duration was conducted using 300 day-old ‘Cobb’ chicks to study the effect of multi-enzyme (involving equal proportions of Cellulase, Amylase, Lipase and Protease) supplemented diets on the overall performance of broilers. The chicks were randomly but equally divided into four groups with 3 replicates and kept under identical managerial conditions. They were allowed to feed commercial broiler ration and multi-enzyme mixture was incorporated in the feed of group I, II, III and IV @ 0.00, 0.10, 0.15 and 0.20 %, respectively. Upto 4 th week, body weight of broiler chicks showed non-significant marginal increase with the multi-enzyme supplemented diet. However, at 6 weeks of age the chicks recorded significant (P<0.05) variations in their body weights and maximum (20%) more weight was observed when multi-enzyme was supplemented @ 0.2% in broiler diet. Feed efficiency was improved by 3.0, 4.5 and 9% when the chicks fed multi-enzyme incorporated diet @ 0.10, 0.15 and 0.20%, respectively. The feed cost to produce one Kg live weight was reduced up to 12.40% due to incorporation of 0.20% multi-enzyme in broiler feed. It may be concluded that incorporation of multi-enzyme @ 0.20% in broiler feed is most beneficial and fruitful and enhanced the margin of profit.
