摘  要:
[目的]研究酵母多糖对鲤鱼生长和免疫功能的影响。[方法]用经超声提取的酵母多糖作为饲料添加剂。试验鲤鱼适应性驯化2周,对照组投喂基础饲料,试验组投喂添加0.1%酵母多糖饲料,每日投饵量均为体重2%,每天在9:00、20:00投喂2次,每次投饵1h后取出残饵。饲喂30d后测定鲤鱼的生长性能、摄食能力,白细胞吞噬功能、脾脏指数、血清溶血素活力、血清杀菌活力等。[结果]基础饲料中添加酵母多糖后,鲤鱼的生长性能和免疫功能相关指标都较对照组显著提高。[结论]为酵母多糖相关产品的开发应用提供试验依据。

摘  要:
[Objective]The research aimed to study the effects of yeast polysaccharides(YPS) on growth performance and immune function of carps.[Method]YPS obtained by ultrasonic extraction was took as feed additive.Carps were adaptive domesticated for 2 weeks.The contrast group was fed with basal feed,and the test group was fed with feed adding 0.1% YPS,and twice per day at 9:00,20:00 feeding with 2% of carps weight.The surplus feed was took out after feeding 1 h.The growth performance,the feeding speed,the phagocytosis of leucocyte,the spleen index,the activity of serum Hemolysin and the serum bactericidal activity and so on.[Result]The results showed that compared with the control group,YPS could enhance growth and immune function of carps.[Conclusion]The study can lay experimental basis for exploring the products correlating with YPS.
