Meishan gilts have distinct uterine characters and gut microbiota compared with LxY gilts. a Representative H&E-stained uterine sections. Scale bar, 1,000 μm and 200 μm. b Endometrial gland area normalized to endometrial area. Length (c) and weigh (d) of Uterine horn. e PCoA based on weighted UniFrac distance show a distinct fecal microbial composition inter-groups. Each data point represents a sample from a distinct sow projected onto the first two principal coordinates (percent variation explained by each PCo is shown in parentheses). f Species diversity analysis of gut microbiota with alpha diversity indices including Observed species, Chao1, ACE, Shannon, Simpson and Good coverage. *P < 0.05, **P < 0.01, ***P < 0.001, data were shown as means ± SEM; n = 7
