摘要
研究了饲料中添加不同剂量的硒元素对中华米虾体内超氧化物歧化酶(SOD)活力的影响.实验表明,饲料中添加微量元素硒对中华米虾体内SOD的激活作用显著,并表现出明显的剂量效应.饲料中添加亚硒酸钠浓度应控制在一定范围内,若高于一定浓度,随着养殖时间的增长,虾体SOD的活性反而会降低.
The effect of selenium supplement in diet of Caridina denticulate sinensis on SOD activity was studied. Results showed that proper concentration of selenium in the diet can enhance SOD activity significantly and stimulate growth of C. d. sinensis a little. The optimum supplement of Na2SeO3 in diet was 0. 15- 0. 30 μg/g.
