g_indicated genus. The unit of the mean was relative abundance (%); Sd meant standard deviation. The intestinal microbiota genera different significantly among three groups were listed in the above table. We applied non-parametric rank sum test in the analysis of relative abundance of intestinal microbiota genera between three groups. * shows P < 0.05.
