Fecal microbiota characteristics in three groups: fed with basal diet (CS) basal diet with 0.3% (w/w) Bacillus amyloliquefaciens-9 (GB-9) (BS), and basal diet with 0.3% (w/w) Radix Tetrastigmae powder (RS) at week 6. Fecal samples were collected at week 6. Bacterial 16S rRNA genes were amplified and sequenced. (A) Alpha diversity (Shannon index). (B) Alpha diversity (Chao 1 index). (C) OTU Venn diagram. (D) PCA analysis. Data are mean ± SEM. * p < 0.05. Statistical analyses were performed using the ANOVA with the SPSS software (SPSS v.19, SPSS Inc., Chicago, IL, USA). * p < 0.05 was considered statistically significant compared with the CS group.
