Effect of Supplementation of Phytase Enzyme in Diet on Growth Performance of Broiler Chicks

Abstract

The research was carried out on broiler chicks to determine the effect of phytase enzyme addition in diet on broiler chick growth. Following one week of brooding, 120 birds were randomly selected and divided into three treatment groups: Phyt-0, Phyt-500, and Phyt-1000, with Phytase enzyme (Phyt) at rates of 0, 500, and 1000 FTU/kg in feed. There were 40 birds in each treatment group, with 10 birds per replicate. The trial was divided into two parts: the starter phase (1-21 days) and the finisher phase (22-35 days). Weekly data on body weight gain and feed consumption were collected, and the weekly feed conversion ratio was calculated using this information. Carscass characteristics were measured at end of trial. Birds fed diet supplemented with higher phytase occupied higher growth performance and better carcass characteristics. Birds fed a diet high in phytase performed better in terms of growth.
