Extended error bar plot showing the mean proportion (%) showing trend or significant variation a of different cecal bacteria communities between no xylanase (Xyl0) and 16,000 BXU/kg xylanase (Xyl100) groups in broilers at d 42 post-hatch b predicted functions of cecal microbial communities between no xylanase (Xyl0) and 16,000 BXU/kg xylanase (Xyl100) groups in broilers at d 42 post-hatch, and c predicted functions of cecal microbial communities between no xylooligosaccharides and 100 g/t xylooligosaccharides groups of broilers at d 42 post-hatch. The sphere points in blue and orange indicate the difference between a, b no xylanase and 16,000 BXU/kg xylanase groups, and c no xylooligosaccharides and 100 g/t xylooligosaccharides groups. The P-value on the right was derived from a White’s non-parametric t-test in the statistical analysis of taxonomic and functional profiles (STAMP) software
