ABSTRACT This study evaluated the effects of xylanase combined with increasing amylase levels in broiler diets containing protease and phytase on performance, intestinal histomorphology, cecal short-chain fatty acid profile, serum interleukin (IL) levels, and economic viability over a 28-d period. A completely randomized experimental design was adopted in a 2 × 3 + 1 factorial arrangement (100 or 200 U kg−1 amylase × 0, 1,000 and 2,000 U kg−1 xylanase + positive control (PC), without enzymes), with seven replicates of […]

The objective of this study was to evaluate the effect of the supplementation of xylanase in diets with reduced energy level on the apparent metabolizable energy corrected for nitrogen, determined with laying hens at 14, 36, 60 and 80 weeks of age. Four digestibility trials were conducted, using 80 Hy-line W36 laying hens aged 14, 36, 60 and 80 weeks of age. Birds were distributed in a completely randomized design in 2 × 2 factorial arrangement (energy level × inclusion […]
