dc.description.abstract To study the effect of resveratrol on the antioxidant system of Litopenaeus vannamei, resveratrol (0, 40, 80, 120 and 180 mg/kg) was added to the feed. After 7 days of culture, 10 tails of L. vannamei were randomly selected and exposure to ammonia stress at the sublethal concentration of ammonia (20 mg/L) for 24h. The results showed that the malondialdehyde (MDA) level in serum of shrimp fed with resveratrol decreased significantly compare to the control group (p< 0.05). After the ammonia stress, the MDA levels in serum in the Res 120 group and the Res 160 group was lower significantly than that in the control group (p< 0.05). The activities of superoxide dismutase (SOD) in the hepatopancreas and the serum, and glutathione peroxidase (GPX) in the serum of shrimps fed with resveratrol showed a decrease trend before the ammonia stress. Conversely, the activities of SOD and the total antioxidant competence (T-AOC) levels in the hepatopancreas in the Res 80 group and Res 120 group were significantly higher than that in the control group after the ammonia stress (p<0.05). Dietary resveratrol decreased oxidative damage, increased antioxidant enzyme activities under the ammonia stress. Our results demonstrated that resveratrol attenuated oxidative stress and improved the resistance to the ammonia stress.
