Vitamin E inhibits inflammation and improves immune response of mud crabs (<i>Scylla paramamosain</i>) by activating an antioxidant enzyme system and apoptosis mechanism.

ABSTRACT: An 8-week feeding trial was conducted to evaluate the effects of dietary vitamin E levels on growth, antioxidant status and immune response for mud crabs (Scylla paramamosain). A total of 180 mud crabs (initial weight: 24.16 ± 1.08 g) were fed six different dietary vitamin E levels, where the analyzed vitamin E were 9.65, 34.70, 58.50, 76.30, 102.00 and 199.00 mg/kg, respectively. The results showed that crabs fed with the 76.30 mg/kg vitamin E diet exhibited significantly higher final weight (P = 0.007), percent weight gain (PWG) (P = 0.008) and specific growth rate (P = 0.010) than those fed the diets with 9.65 and 34.70 mg/kg vitamin E. The highest activities of total antioxidant capacity in hemolymph (P = 0.006) and hepatopancreas (P = 0.017),
