| 摘 要： | 研究了饲料中添加量为0、0.15、0.30、0.45、0.60、0.75μg/g的硒,对中华米虾(Caridina denticulatasinensis)体内超氧化物歧化酶(SOD)活力的影响。结果表明,硒对中华米虾体内SOD的激活作用显著,并表现出明显的时间效应和剂量效应。随着养殖时间的延长,各实验组虾体内SOD的活性会相应地降低。饲料中添加硒浓度为0.45μg/g时,虾体SOD的活性最高。

| Abstract: | The effects of selenium supplementation in diet on the activity of SOD in Caridina denticulata sinensis were studied.The optimal concentration of Na_2SeO_3 was determined by the activity of SOD.When Na_2SeO_3 was added in the diet,the activity of SOD changed significantly in a dose-and time-dependent manner.Our results showed that suitable concentration of selenium in the diet significantly enhances the activity of SOD in C.d.sinensis.The activity of SOD decreases with the elongation of breeding time. |
