摘要: 选用罗非鱼120尾,随机分为5组。对照组饲喂基础日粮,试验组分别饲喂在基础饲料中添加100、500、1 000、1 500 mg·kg-1的黄芪多糖试验日粮,投喂40 d。每10 d检测白细胞的吞噬能力和免疫器官增重情况。结果显示:500 mg·kg-1、1 000 mg·kg-1和1 500 mg·kg-1组均能显著提高罗非鱼血液中白细胞吞噬能力,增加免疫器官的重量 (P-1则不明显(P>0.05)。表明黄芪多糖可以不同程度地提高罗非鱼血液中白细胞的吞噬能力,促进免疫器官的发育与成熟。Abstract: One hundred and twenty tilapia were randomly divided into 5 groups in this experiment.Four test groups were fed with basic diet with different levels of astragalus polysaccharides (100, 500, 1 000, 1 500 mg穔g-1), while control group was only fed with basic diet for 40 days.The leukocyte phagocytosis activity and the weight of immune organs of tilapia were detected respectively every ten days.The result showed that group 500 mg穔g-1,1 000 mg穔g-1 and 1 500 mg穔g-1 were significantly different with the control group on phagocytosis activity and the growth of immune organs (P-1 did not have significantly different with the control group (P>0.05).It indicated that astragalus polysaccharides could enhance phagocytosis activity and the growth and maturity of immune organs.
