喂的试用被执行在抗氧化剂活动调查东方河对虾 Macrobrachium nipponense (0.3-0.4 g 的重量) 和它的效果角色的饮食的维生素 E 要求。对虾用维生素 E (0, 25, 50, 75, 100, 200,和 400 mg/kg 食谱) 的七个层次被喂 60 天。结果显示出那饮食的维生素 E 补充能显著地增加了对虾重量(P < 0.05 ) 。在 hepatopancreas 的 superoxide dismutase (草皮) 的活动在用食谱比在用食谱与 100-400 mg/kg 维生素 E 补充了喂的那些与 75 mg/kg 维生素 E 补充了喂的对虾是显著地更高的(P < 0.05 ) 。当饮食的维生素 E 补充增加了,在 hepatopancreas 的过氧化氢酶(猫) 的活动显著地减少了(P < 0.05 ) ,并且没有重要差别在谷胱甘肽 peroxidase (GSH-Px ) 被检测在不同的饮食的组之间的活动(P > 0.05 ) 。在 hepatopancreas 并且在肌肉的维生素 E 的内容与增加饮食的维生素 E 增加了。在 hepatopancreas 在肌肉在在饮食和那的维生素 E 水平之间,并且在在饮食和那的维生素 E 水平之间有线性关联。所有上述结果显示饮食的维生素 E 能在 hepatopancreas 和肌肉被存储并且两个都在 hepatopancreas 降低草皮和猫的活动,建议它是在 M 的一种潜在的抗氧化剂。nipponense。在每个食谱组在对虾的重量获得上进行的破线分析证明为最大的生长的饮食的维生素 E 要求是 94.10 mg/kg。
A feeding trial was carried out to investigate the dietary vitamin E requirement of the oriental river prawn Macrobrachium nipponense (weight of 0.3-0.4 g) and its effect role on antioxidant activity. Prawns were fed with seven levels of vitamin E (0, 25, 50, 75, 100, 200, and 400 mg/kg diet) for 60 days. The results show that dietary vitamin E supplementation could significantly increased the prawn weight (P〈0.05). The activity of superoxide dismutase (SOD) in the hepatopancreas was significantly higher in prawns fed with diets supplemented with ≤75 mg/kg vitamin E than in those fed with diets supplemented with 100-400 mg/kg vitamin E (P〈0.05). The activity of catalase (CAT) in the hepatopancreas decreased significantly as dietary vitamin E supplementation increased (P〈0.05), and no significant difference was detected in glutathione peroxidase (GSH-Px) activity between different dietary groups (P〉0.05). The contents of vitamin E in the hepatopancreas and in the muscle increased with increasing dietary vitamin E. There was a linear correlation between the vitamin E level in diet and that in muscle, and between the vitamin E level in diet and that in the hepatopancreas. All the above results indicated that dietary vitamin E can be stored in the hepatopancreas and muscle and lower both the activities of SOD and CAT in the hepatopancreas, suggesting that it is a potential antioxidant in M. nipponense. Broken line analysis conducted on the weight gains of prawns in each diet group showed that the dietary vitamin E requirement for maximum growth is 94.10 mg/kg.
