Intestinal microbiota structure of the Arbor Acres broilers and the Beijing-You broilers. (A) Graph of microbiota composition. (B) Alpha diversity analysis of the Chao1 index and the Shannon index. (C,D) Scatterplot from nonmetric multidimensional scaling (NMDS) in bacterial composition. (E,F) Venn diagram of unique operational taxonomic units (OTUs) in ileum and cecum. (G,H) Microbiota structure at the phylum level in ileum and cecum. AA: the Arbor Acres broilers; BY: the Beijing-You broilers. The numbers of independent biological samples analyzed in panel B to H were AA (n = 5) and BY (n = 5). Data in (B) are expressed as mean ± SEM. Data in (B) were analyzed using ANOVA followed by the Tukey's test and were considered as statistically significant at *p < 0.05 between the indicated groups. Data in (C,D) were analyzed using nonmetric multidimensional scaling. Data in (C–H) statistical tests were two-sided and differences were considered to be statistically significant at p < 0.05.
