Development of the mucosa-associated microbiota in the small and large intestines of Rongchang and Landrace piglets during the first 35 days after birth. a Stacked area plot displaying the changes in the relative abundance (%) of the 15 most abundant bacterial families with age. b The shift of α-diversity (Shannon index) with age across 4 intestinal segments. c The shift of β-diversity (unweighted UniFrac distance) with age across 4 intestinal segments. The β-diversity at each time point is the average distance of one sample to all other samples at that time point
