摘　　要：本研究旨在探究茯苓提取物对家兔生长性能及免疫功能的影响。试验采用单因素随机试验设计,随机挑选健康、体重相近的100只30日龄的断奶仔兔,随机分为4组,每组5个重复,每个重复5只。试验Ⅰ、Ⅱ和Ⅲ组分别在每千克基础日粮中添加0.5、1.0和2.0g的茯苓多糖,换算添加比例分别为0.05%、0.1%和0.2%。预饲期7d,正试期42d。结果表明,试验组平均日增重显著高于对照组(P <0.05),料重比显著低于对照组(P <0.05),试验Ⅰ、Ⅱ和Ⅲ组平均日增重分别较对照组显著增加1.79、1.56和0.77g/d(P <0.05);与对照组相比,试验组IgA和IgG含量显著提升(P <0.05),TNF-α含量显著降低(P <0.05);试验Ⅱ、Ⅲ组IL-6含量显著低于对照组(P <0.05),试验组IL-10含量均显著高于对照组(P <0.05)。综上所述,添加茯苓多糖能提高家兔平均日增重,降低料重比,改善机体免疫水平。在本试验条件下,家兔中茯苓多糖的适宜添加水平为0.1%。This study aims to investigate the effects of Poria cocos extract on the growth performance and immune function of rabbits.The experiment adopts a single factor randomized trial design,randomly selecting 100 healthy and similar weight 30 day old weaned rabbits,and dividing them into 4 groups randomly,with 5 replicates in each group,and 5 rabbits in each replicate.Experiment groups I,II,and III added 0.5,1.0,and 2.0 g of Poria cocos polysaccharides per kilogram of basal diet,with conversion ratios of 0.05%,0.1%,and 0.2%,respectively.The pre feeding period is 7 days,and the trial period is 42 days.The results showed that the average daily weight gain of the experimental group was significantly higher than that of the control group(P<0.05),and the feed to weight ratio was significantly lower than that of the control group(P<0.05).The average daily weight gain of the experimental groups I,II,and III increased significantly by 1.79,1.56,and 0.77 g/d compared to the control group,respectively(P<0.05);Compared with the control group,the experimental group had IgA and IgG significant increase in content(P<0.05),TNF-αThe content significantly decreased(P<0.05);The IL-6 content in experimental groups II and III was significantly lower than that in the control group(P<0.05),while the IL-10 content in experimental groups was significantly higher than that in the control group(P<0.05).In summary,adding Poria cocos polysaccharides can increase the average daily weight gain of rabbits,reduce the feed to weight ratio,and improve the body's immune level.Under the conditions of this experiment,the appropriate level of Poria cocos polysaccharides added to rabbits is 0.1%.
