Effects of TUDCA supplementation on the intestinal morphology and mucosa mucopolysaccharide of weaned piglets (n = 6). A The intestinal morphology of the jejunum and ileum with H&E staining (scale bar, 1000 μm). B Statistical diagram of the villus height-to-crypt depth ratio in the jejunum and ileum. C The intestinal mucosa mucopolysaccharide of jejunum and ileum stained with periodic acid-schiff (PAS) (scale bar, 200 μm). D Statistical diagram of the number of PAS positive cells in each villus. *P < 0.05, versus the CON group
