Dietary Inclusion of Pancreatin Enzyme on the Ileal and Fecal Digestibility of Nutrients in Layer-Type Cockerels

Abstract

ABSTRACT The current experiment aimed to evaluate the effects of Pancreatin supplementation at different levels on ileal and fecal digestibility in layer-type cockerels. A total of 480-day-old silver brown Hy-Line male chicks were randomly allocated into 5 treatments, 6 replicates (16 birds per pen) arranged in a completely randomized design. Pancreatin enzyme was supplemented on a basal corn-soybean meal-based diet at 0, 250, 500, 750, and 1000 mg/kg and was fed in two growth phases (starter and grower). The results indicated that at the end of the starter stage, except for 1000 mg/kg, dietary Pancreatin supplementation levels increased (p0.05) on nitrogen digestibility (ND), nitrogen retention (NR), digestible energy (DE), apparent metabolizable energy (AME), dry matter digestibility (DMD), dry matter retention (DMR), and apparent metabolizable energy corrected for nitrogen (AME-n) on fed starter diet. On the other hand, at the end of the grower stage, dietary Pancreatin enzyme supplementation reduced (p<0.05) the ileal CP, MIAA, MDAA, MTAA, AIAAD, AME, AME-n, ND, NR, DE, DMD, and DMR in a dose-dependent manner. The rate of reduction was more marked on Pancreatin addition level 1000 mg/kg. In conclusion, Pancreatin supplementation at 250 mg/kg, 500 mg/kg, and 750 mg/kg improved AIAAD and ileal CP, especially at the young age. The rate of pancreatin enzyme effect was dependent on enzyme supplement level to the ileal CP and individual amino acid.
