Abstract

This study was conducted to measure the influence of varying levels of commercial dietary multi-enzyme NutriKEM Extend supplementation on broiler performance and carcass characteristics. One hundred seventy five, one-day-old chicks were completely distributed into five treatments groups in a randomized design. Each group consisted of five replicates of seven unsexed Cobb 500 birds. The same iso-caloric and ios-nitrogenous diet based on sorghum and groundnut cake was fed in mash form to all experimental groups. Group (A), the control group, was fed on the un-supplemented diet that did not receive multienzymes. Additionally, multi-enzymes were supplemented for the remainder groups (B, C, D and F) in a graded four levels of application (250, 500, 750 and 1,000g/ 1,000 Kg feed respectively). Enzymes supplementation apparently increased body weight and body weight gain, whereas feed intake, FCR and economic efficiency were not significantly affected. Dietary multi-enzyme supplemented diets showed no effect on commercial cuts proportions, organs relative weights and economic appraisal. In conclusion, the use of multi-enzyme could improve broiler general performance irrespective to the multienzyme added level.
