Performance, energy, and nutrient utilization benefits with exogenous enzyme supplementation of wheat-soybean meal-based diets fed to 22-day-old broiler chickens

This study was designed to investigate the performance, bone quality, and nutrient and energy utilization in broiler chickens fed wheat-soybean meal-based diets with a dietary multi-enzyme complex. The positive control (PC) diet met or exceeded energy and nutrient needs, while the negative control (...

description This study was designed to investigate the performance, bone quality, and nutrient and energy utilization in broiler chickens fed wheat-soybean meal-based diets with a dietary multi-enzyme complex. The positive control (PC) diet met or exceeded energy and nutrient needs, while the negative control (NC) diet was formulated to contain 3.0, 16.7, and 33.3% less of AMEn, Ca, and avP, respectively. Enzyme complex was supplemented to the NC diet at 0, 150, 200, or 250 mg/kg during the pre-starter (d 0-9) and starter (d 9-22) phases. A total of 300 d-old male broiler chicks were assigned to the 5 treatments in a randomized complete block design with 10 replicate cages of 6 chicks per cage. Data were analyzed using the GLM procedures of SAS. Birds fed the NC diet had lower (P < 0.01) average daily gain, average daily feed intake, and feed efficiency (FE) compared to those fed the PC diet (d 0-22), while the chickens fed enzyme supplemented diets had similar (P > 0.05) performance to those fed the PC diet. Average daily feed intake (d 9-22 and 0-22) and FE (d 9-22) rose linearly (P < 0.05) with the level of enzyme supplementation. There were linear and quadratic (P < 0.001) relationships for jejunal digesta viscosity, tibia bone breaking strength and tibia ash with enzyme supplementation level. Birds fed the NC diet had lower (P < 0.05) apparent ileal digestibility and utilization of DM, N, digestible energy, and AMEn, but higher (P < 0.05) Ca digestibility and utilization compared with birds fed the PC diet. Higher levels of enzyme supplementation resulted in a quadratic relationship (P = 0.005) with P digestibility and a linear relationship (P < 0.001) with P utilization. Ileal digestibility of nonessential amino acids was quadratically related (P < 0.05) with enzyme supplementation except for Glu and Tyr (P < 0.01). This study showed that growth performance, energy and nutrient utilization, and bone mineralization were maintained with a supplemental multi-enzyme complex in a reduced energy and nutrient wheat-soybean meal-based diet.
