Effects of dietary fermented Chinese herbal medicines on growth performance, digestive enzyme activity, liver antioxidant capacity, and intestinal inflammatory gene expression of juvenile largemouth bass (Micropterus salmoides)

This study aimed to evaluate the effects of fermented Chinese herbal medicines (FCHM) on growth performance, digestive enzyme activity, antioxidant capacity and intestinal inflammatory gene expression of juvenile largemouth bass (Micropterus salmoides). Four trial diets H0 (basal diet), H1, H2, and H3 (added 1 %, 3 %, and 5 % FCHM to the basal diet, respectively) were prepared.
