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 per Driselase (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 per Driselase @ 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 per Driselase, during finisher phase had no effect (P greater than 0.05) on GBW, DMI and FE. It was concluded that the addition of per Driselase in the finisher ration has no beneficial effects on the growth performance of broiler chicks.
