The effects of ZnO and coated ZnO (C_ZnO) on the intestinal mucosal morphology. (A) H&E staining of ileal tissue in piglets and the analysis of intestinal morphology. (B) H&E staining of colonic tissue in piglets and the analysis of intestinal morphology. Data are expressed as mean ± SEM, n = 6. *P < 0.05, **P < 0.01. CON, basal diet; ZnO, a basal diet supplemented with ZnO (2,000 mg Zn/kg); C_ZnO, a basal diet supplemented with C_ZnO (500 mg Zn/kg); V, villus height; C, crypt depth; V/C, the ratio of the villus height to crypt depth.
