Stacked bar graph displays a comparison of microbial relative abundance (%) at phylum level among main effects (xylanase and xylooligosaccharides) of treatments in broilers at d 42 post-hatch. The label P denotes xylooligosaccharides prebiotics, and the label E denotes xylanase enzyme for each sample. The letters (a, b, c, and d) denote replicate samples. P1: 0 g xylooligosaccharides per ton feed, P2: 50 g xylooligosaccharides per ton feed, P3: 100 g xylooligosaccharides per ton feed. E1: xylanase 0 BXU/kg or 0 g per ton feed, E2: xylanase 8,000 BXU/kg or 50 g per ton feed, E3: xylanase16,000 BXU/kg or 100 g per ton feed
