Effects of pectin on the jejunum microbial diversity. A Venn diagram; B The alpha diversity indices (Sobs); C The beta diversity presented by the PCoA plot based on the OTU level; D The abundance of the intestinal microbiota composition at the phylum level; E Differences in microbial community composition between two groups at phylum level; F The abundance of the intestinal microbiota composition at the genus level; G Differences in microbial community composition between two groups at phylum level. Data were expressed as mean ± SEM, n = 8. ^*P < 0.05; ^**P < 0.01; ^***P < 0.001
