摘　　要：文章旨在研究饲料中添加不同含量水平的黄芪多糖对台湾泥鳅苗生长性能、器官指数及抗氧化能力的影响。试验选取270尾健康的台湾泥鳅鱼苗,初始体长(6.23±0.78)cm,体重(2.51±0.08)g。鱼苗随机分为3组,每组3个重复,每个重复30尾。各组台湾泥鳅苗分别饲喂基础饵料+0、200、400 mg/kg黄芪多糖,试验为期62 d。结果表明:1)与0 mg/kg黄芪多糖组相比,200、400 mg/kg黄芪多糖组泥鳅的末重显著提高10.06%、37.74%(P<0.05),特定生长率显著升高15.53%、50.49%(P<0.05),增重率显著升高20.31%、80.81%(P<0.05)。2)3组泥鳅的肝体比、脏体比无显著差异(P>0.05)。3)与0 mg/kg黄芪多糖组相比,400 mg/kg黄芪多糖组总抗氧化能力显著提高(P<0.05),200 mg/kg黄芪多糖组总超氧化物歧化酶活性显著提高(P<0.05),200、400 mg/kg黄芪多糖组溶菌酶活性显著提高(P<0.05),丙二醛显著降低(P<0.05)。由此可见,在饲料中添加400 mg/kg黄芪多糖可提高台湾泥鳅苗的生长性能,改善抗氧化能力。This article aims to explore the effects of adding different levels of Astragalus polysaccharides to feed on the growth performance,organ index,and antioxidant capacity of Taiwan Residents loach seedlings.270 healthy Taiwan Residents loach fry were selected,with an initial body length of(6.23±0.78)cm and a weight of(2.51±0.08)g.Fish fry were randomly divided into 3 groups,with 3 replicates in each group,each with 30 tails.Each group of Taiwan Residents loach fry was fed with basic diet+0,200,and 400 mg/kg Astragalus polysaccharides,respectively,for a period of 62 days.The results showed that:1)Compared with the 0 mg/kg astragalus polysaccharide group,the final weight of loach in the 200 and 400 mg/kg astragalus polysaccharide groups significantly increased by 10.06%and 37.74%(P<0.05),specific growth rates significantly increased by 15.53%and 50.49%(P<0.05),and weight gain rates significantly increased by 20.31%and 80.81%(P<0.05).2)There was no significant difference in the liver to body ratio and organ to body ratio among the three groups of loaches(P>0.05).(3)Compared with the 0mg/kg astragalus polysaccharide group,the total antioxidant capacity of the 400 mg/kg astragalus polysaccharide group was significantly increased(P<0.05),the total superoxide dismutase activity of the 200 mg/kg astragalus polysaccharide group was significantly increased(P<0.05),the lysozyme activity of the 200 and 400 mg/kg astragalus polysaccharide groups was significantly increased(P<0.05),and malondialdehyde was significantly reduced(P<0.05).It can be seen that adding 400mg/kg Astragalus polysaccharides to the feed can improve the growth performance of Taiwan Residents loach seedlings and improve their antioxidant capacity.
