The Effect of Addition Microbial Phytase on the Performance of Broiler Chickens Fed Durra, Corn, Soybean and Groundnut Seedcake Based Diet

Abstract

An experiment was conducted to investigate the effect of using microbial phytase enzyme to improve the utilization of plant phosphorus and .as a consequence improvement in performance parameters Two dietary treatments were compared; treatments consisted of broiler starter and grower rations based on corn, sorghum, soya and groundnut seed cake. Diets were fed with or without the addition of phytase enzyme at the level of 0.1%. Feed intake, body weight and feed conversion were .determined weekly, start from week 2 and up slaughter age at week 6 The results show that the addition of microbial phytase enzyme to diets consist mainly of different grains and oilseed meals result in numerical but not significant improvement in the broiler performance. This could be due to the fact that these plant sources specifically do not contains the .substrate the enzyme is designed to hydrolyze
