dc.description.abstractSix groups of experimental diets containing different levels (14.9, 22.4, 28.6, 37.9, 42.0 and 77.5 mg/kg) of niacin were formulated. Juvenile golden pompano (initial body weight:7.82±0.07 g) were fed in cages for eight weeks. Results showed that moderate niacin in the diet significantly increased (P<0.05) weight gain rate (WGR), specific growth rate (SGR), and feed efficiency (FER). Dietary niacin levels increased the protein content in whole fish and muscle (P < 0.05). The content of serum high density lipoprotein cholesterol (HDL-C) and total cholesterol (TCHO) increased significantly and triglyceride (TG) content decreased significantly (P<0.05). C3 and C4 content in serum, and activities of lysozyme (LZM), and alkaline phosphatase (ALP) increased significantly (P<0.05). Dietary niacin levels significantly increased (P<0. 05) the catalase (CAT), alkaline phosphatase (ALP), and total antioxidant capacity (T-AOC) of the liver when niacin content was more than 28.6 mg/kg. Dietary niacin levels also improved intestinal digestion and absorption by increasing glutamyl transferase (γ-GT)activity. Quadratic regression analysis on WGR indicated that the optimum dietary niacin level for optimal growth of juvenile golden pompano was 29.85 mg/kg.
