Effect of dietary Moutan cortex radicis on the colonic microbiota diversity and composition in the pigs. (A) A Venn diagram illustrating the overlaps of OTUs in the gut microbiota; (B) The microbial alpha diversity indices (Observed-species, Chao1, Shannon, Simpson, ACE) were calculated using the mothur program; (C) Principal coordinate analysis (PCoA); (D) non-metric multidimensional scaling (NMDS) analysis; (E) unweighted UniFrac cluster tree based on Unweighted Pair-group Method with Arithmetic Mean (UPGMA) analysis; (F) The significant different species among groups based on MetaStat analysis. CON, control group, basal diet without antibiotics; LMC, the control diet + 2,000 mg/kg Moutan cortex radicis; MMC, the control diet + 4,000 mg/kg Moutan cortex radicis; HMC, the control diet + 8,000 mg/kg Moutan cortex radicis. Data are expressed as means ± SEM (n = 6). *P < 0.05, **P < 0.01, and ***P < 0.001.
