Effect of Maxigrain® enzyme supplementation of dietary brewers dried grain on the performance, digestibility and economic of production of starter broiler chickens

Abstract

Two hundred and forty Arbor Acre strain day old chicks were used to determine the effect of Maxigrain® enzyme fortification of dietary brewers  dried grains (BDG). Eight groups of 30 birds each were fed four diets that contain 0, 5, 10 and 15 % BDG with or without Maxigrain® in a 2x4 factorial arrangement. The research lasted for 28 days during which data were collected on performance, nutrient utilization and production cost. Significant  (P<0.05) increased was observed in average final body weight, body weight gain and feed intake as dietary BDG increased. However, this effect was higher when enzyme was added to BDG respectively. Increasing the BDG from 0 – 15 % significantly (P<0.05) reduced cost of feed consumed and increased feed cost with enzyme addition. The reversed trend was observed with cost per kg gain of broiler chicks fed BDG with enzyme  supplementation. Birds fed BDG with enzyme had significantly (P<0.05) better nutrient utilization than their counterpart group. It can be concluded that the incorporation of up to 15 % BDG with 100 mg/kg Maxigrain® supplementation enhanced performance and economics of production.
