Effects of dietary lipid levels on growth, fatty acid composition, antioxidant status and lipid metabolism in juvenileOnychostoma macrolepis

Five diets of different lipid levels, 3%, 6%, 9%, 12% and 15% (L3, L6, L9, L12 and L15), were designed and fed to juvenile Onychostoma macrolepis for 8 weeks. The juvenile O. macrolepis grew better at L9 than at L3, L6 and L15 (p < .05). The viscera and hepatopancreas indexes increased as the dietary lipid levels increased. There appeared lower serum TG and HDL levels at lipid levels of 3.01%–9.01% (p < .05). Hepatic histology showed that the...
