Fig. 3From: Dietary carbon loaded with nano-ZnO alters the gut microbiota community to mediate bile acid metabolism and potentiate intestinal immune function in fattening beef cattleSecondary BA synthesis pathway analysis displaying the change between two groups. A differ secondary BA synthesis pathway, (B) differ enzyme. CON, control; NZnOC, carbon loaded with nano-ZnO. Cattle were regarded as the experimental units, n = 5/group. *p < 0.05, ***p < 0.001Back to article page
