|Differences in microbial diversity and composition between low-fatness and high-fatness. A The experimental design of this study. B Comparison of the Shannon index in the three intestinal segment regions between the two groups. Mann-Whitney U test was performed to verify the differences, where p < 0.05 indicates significant difference. Partial least squares discriminant analysis of the composition of microbial species in the three intestinal segments. C Relative abundance of the top 10 microbial species at the phylum, class, family and genus level in the three intestinal regions of the two groups
