Influence of exogenous multi-enzymes in broiler chickens fed on maize-wheat-soybean meal-based diets

Abstract

Summary This study evaluated the effects of multi-enzyme (xylanase, mannanase, β-glucanase, cellulase, pectinase, and amylase) supplementation on growth performance, nutrient digestibility, blood characteristics, relative organ weight, and breast muscle quality in broilers fed maize-wheat-soybean meal-based diets. A total of 800, one-day-old Ross 308 broiler chicks were randomly assigned to one of 4 treatments according body weight (body weight, 45.3 ±Â 0.72 g) in a 35-day trail. Each treatment had 10 replicate cages with 20 birds per replicate cage. Dietary treatment groups were: (1) CON, maize-wheat-soybean meal basal diet; 2) ME60, CON + 60 mg/kg multi-enzyme; 3) ME120, CON + 120 mg/kg multi-enzyme; 4) ME180, CON + 180 mg/kg multi-enzyme.
