Diversity and richness of the gut microbiota in rats.

(a–c) shows the Rarefaction curves at 0^th, 8^th and 18^th week, respectively; (e–g) shows the Shannon curves at 0^th, 8^th and 18^th week, respectively; (d,h) shows the Rarefaction OTU estimates and Shannon index of each group at the 18^th week after rarefying the sequencing depth to 1500 for all the samples. Values are expressed as means ± standard error. Differences were assessed by ANOVA and denoted as follows: ^***P < 0.001; ^NS not significant.
