Two types of bile acids (BAs), named fermented bile acids (FBAs) and 170HDa, were produced by a biological approach to assess their effects on growth performance, metabolism, and intestinal health in white shrimp. In this study, five experimental diets were prepared with varying levels of FBAs (0.02% for A1, 0.03% for A2, 0.04% for A3, 0.05% for A4, and 0.06% for A5) and five diets containing different concentrations of 170HDa (0.02% for B1, 0.03% for B2, 0.04% for B3, 0.05% for B4, and 0.06% for B5). Additionally, positive diets (P) with commercial BAs at a level of 0.04%, along with and negative diet (N) without BA supplementation, were included as controls. FBAs and 170HDa were found to improve the growth performance including final weight, weight gain, and specific growth rate and reduce the activities of aspartate aminotransferase and alanine aminotransferase in hemolymph. The alkaline phosphatase (AKP) activity of hemolymph in shrimp treated with FBAs was generally higher than in groups treated with 170HDa and the control groups. However, the acid phosphatase (ACP) activity of hemolymph in shrimp treated with FBAs showed similar levels to those treated with 170HDa and the control groups. The gene expression levels of antilipopolysaccharride factor (ALF) and proPO were significantly lower in most FBAs and 170HDa-treated groups compared to the control groups (
