在基础饲料中添加不同剂量的果寡糖(每kg饵料含量分别为0、0.5、2和4 g),连续投喂,分别于试验前1 d、试验第7天、第14天、第21天、第28天、第42天、第56天检测草鱼血液白细胞吞噬活性、血清溶菌酶活性和补体C_3、C_4的含量.结果表明,试验组草鱼的各免疫指标均有不同程度的提高,且果寡糖添加剂量为2 g/kg时各试验指标与对照组差异显著,同时优于其它两试验组,而且其攻毒死亡率最低.因此,从提高免疫力和经济角度考虑,建议果寡糖添加剂量为2 g/kg为宜.

In order to study the effect of fructooligosaccharides on non-specific immunity of Ctenopharyngodon idellus,the fish were fed with diets containing fructooligosaccharides 0,0.5,2 and 4 g/kg respectively for 56 days.Phagocytic activity of leukocytes,lysozyme activity and the content of complement C_3 and C_4 in serum were studied on 0,7th,14th,21st,28th,42nd and 56th day.The results showed that the immune indexes of experiment groups were markedly enhanced,especially in the group of 2 g/kg fructooligosaccharides in diet (P<0.05).The group with 2 g/kg addition in diet had lower mortality than the other groups.We suggested that 2 g/kg addition was suitable from the aspects of immunity and economy.
