Abstract: The main objective of the present study was to evaluated the effects of different levels of locally avaiable Driselase-1 (amylolytic, proteolytic and cellulolytic enzymes mixture), when added in the starter rations of broiler chicks. The effectiveness of such enzymes was measured in terms of gain in body weight, dry matter intake (DMI) and feed efficiency. One hundred and ninty two day old chicks were randomly distributed into 4 main groups, A, B, C and D, where each main group was further divided into 4 sub groups contained 12 birds each. Four experimental diets viz, I, II, III and IV were randomly allotted to these groups. All the four diets were containing 1 kg (basal feed ingridients) added with 0, 1, 2, and 4 g/kg Driselase-1. Each ration was offered ad libitum. The experiment lasted for 21 days. The data were statistically analyzed using Completely Randomized Design. Enzuyme treatment highly (P<0.01) effected the gain in body weight and feed efficiency, but slightly (P<0.05) effected the DMI of the experimental birds. Ration IV resulted the highest improvement in the pre-mentioned parameters compared with Rations. I, II and III. it was concluded that enzyme addition successfully improved the over all performance of the experimental birds. Further research work is needed to use higher level of such enzymes mixture in broiler finisher ration. It is also suggested that the effect of Fdriselase-12 should be tested on commercial layer. Moreover, the economics of the experimental rations should be calculated.
