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 […]
