Effects of dietary enzyme on broiler chickens feddiets containing wheat bran

Abstract

Two hundred and eighty-eight 3-week-old mixed-sex broiler chickens were randomly divided into three dietary treatment groups and fed diets containing 0, 100 or 200 g/kg of dietary enzyme, respectively, for four weeks. Feed and water were supplied ad libitum. The parameters studied included growth rate, feed consumption, feed conversion ratio, carcass evaluation, and the economics of production.
