NUTRITIONAL IMPORTANCE OF EXOGENOUS ENZYMES IN BROILER RATION AT FINISHER PHASE

The present study was conducted at Akbar Poultry Farm Tehsil Munda, Timergara, District Lower Dir, North West Frontier Province during 2006. The aim of the trial was to evaluate the nutritional importance of Driselase-1 (a mixture of amylase, protease and cellulose) for commercial broiler chicks. Gain in body weight (GBW), dry matter intake DMI) and feed efficiency (FE) were the main parameters. For this purpose, one hundred and ninety two, 21 days old chicks were randomly distributed into 4 main groups, A, B, C and D, each group was subdivided into 4 sub-groups contained 12 birds each. Four experimental diets were randomly allotted to these 16 sub-groups. All the 4 diets had 1 kg (basal feed ingredients) plus Driselase-1 @ 0, 1, 2 and 4 g/kg. The rations were offered ad libitum twice daily. The data were statistically analyzed, using completely randomized design. The experiment was lasted for 21 days. Feeding Driselase-1, during finisher phase had no effect (P 0.05) on GBW, DMI and FE. It was concluded that the addition of Driselase-1 in the finisher ration has no beneficial effects on the growth performance of broiler chicks
