Effect of supplementing a enzyme mixture in sorghum+soybean meal diets on apparent ileal amino acid and protein digestibility, metabolizable energy, and productivity in broilers
The effect of addition of a commercial enzyme mixture (pectinases, â-glucanases and hemicellulases) to sorghum+soybean meal diets on apparent ileal amino acid and protein digestibility, metabolizable energy and productive performance in broiler was evaluated with two experiments. Both experiments included four treatments: 1. Control, sorghum+soybean meal diet, 2. Control diet + enzymes, 3. Low-nutrient sorghum+soybean meal diet (7 % reduction in crude protein (CP), amino acids (AA) and metabolizable energy (ME), and 4. Low-nutrient diet + enzymes. A completely randomized design with a 2 x 2 factorial arrangement was used in both experiments, one factor was diets (control and low-nutrient) and the other factor was addition or not of enzymes. Exp 1 included 240 Ross 308 broiler chicks in a trial from 1 to 21 d of age, and Exp 2 included 280 Ross 308 chicks in a trial from 1 to 49 d of age. At 21 d in Exp 1, weight gain was lower (P
