Effect of vitamin A supplement on the growth performance, antioxidant status, and lipid accumulation of Chinese mitten crab Eriocheir Sinensis fed different lipid levels

This study evaluates the influence of dietary vitamin A on growth performance, antioxidant capacity, and lipid metabolism Eriocheir sinensis juveniles (3.95 ± 0.12 g) fed different levels. Crabs were with four diets, including normal (7%) devoid (0 IU/kg, NL-VAD), supplement (6000 NL-VAS), high (13%) HL-VAD), HL-VAS) for 8 weeks. The significant interaction between level was found in weight gain, specific rate, mRNA synthesis related genes retinoid X receptor. Under supplementation did not affect final body weight, rate. Regardless levels, enhanced activities relevant indices (total superoxide dismutase, glutathione peroxidase). Vitamin also reduced excessive malondialdehyde hepatopancreas caused by high-fat diets.
