饲料中硒和α-硫辛酸对皱纹盘鲍稚鲍抗氧化反应的影响
Interaction Between Selenium and o-Lipoic Acid on Antioxidative Responses of Juvenile Abalone Haliotis discus hannai Ino
摘要
Abstract
A 2 × 3 two-factorial experiment was designed to investigate effects of dietary selenium and α-lipoic acid on antioxidative responses of juvenile abalone Haliotis discus hannai (initial weight: (0.43±0.00) g).Six semi-purified diets were formulated to provide graded levels of selenium (0 and 1 mg/kg)and α-lipoic acid (0, 800 and 3 200 mg/kg), one of which was fed to a triplicate group of abalone for 16 weeks in a flow-through water system.The results showed that dietary selenium significantly increased glutathione peroxidase (GPX) and total antioxidative capacity (T-AOC) (P ＜ 0.05) in hepatopancreas when diet contained no α-lipoic acid.Diet containing 800 mg/kg α-lipoic acid significantly improved total superoxide dismutase (SOD), GPX and T-AOC value in hepatopancreas, respectively (P＜0.05), and glutathione (GSH) in hepatopancreas were also increased although no significant differences were found among treatments (P＞0.05).But diet with 3 200 mg/kg α-lipoic acid significantly decreased GPX and TAOC in hepatopancreas.Although no statistically significant interaction was found, dietary selenium and α-lipoic acid showed potential interaction on antioxidative responses of abalone.Based on these results,abalone showed better antioxidative responses when fed diet supplemented with 1 mg/kg Se and 800 mg/kg α-lipoic acid.关键词
