The abundance and diversity of microbial community in cecal contents of broilers at day 28. (A) The Venn diagram summarizing the numbers of common and unique OTU in the microflora community in cecal contents of broilers. (B) The UPGMA Cluster Tree displaying the relative abundances of predominant bacteria at the species level in each group (unweighted UniFrac distance). (C) The principle component analysis (PCA) plot about the cecal microflora. (D) The Shannon index reflecting species diversity within and between groups. (E, H) The top 10 relative abundance of microflora community (level family and level species) indicate by histogram. (F, G, I–K) The some bacteria with significant differences between groups (level family, level species) indicate by histogram. Abbreviations: ANT, basal diet supplemented with 30 mg/kg bacitracin; GML1, basal diet supplemented with 500 mg/kg α-GML; GML2, basal diet supplemented with 1,000 mg/kg α-GML; NCO, basal diet provided as the control; OTU, operational taxonomic unit; UPGMA, unweighted pair-group method with arithmetic mean. Bars represent mean ± SD (n = 6). ∗Means different (P < 0.05), ∗∗means significant difference (P < 0.01).
