益生菌·黄芪多糖微胶囊制剂对肉仔鸡生长性能·免疫器官指数及血液生化指标的影响

Effects of Microcapsule of Profitable Microbe and Astragalus Polysaccharide on Growth Performance,Immune Organ Index and Blood Biochemical Index of Chicks

选用1日龄健康艾维茵肉仔鸡288只,随机分为6个处理,每个处理4次重复,每个重复12只鸡,试验组在基础日粮中分别添加益生菌Ⅰ、益生菌Ⅱ、黄芪多糖、合生元和微胶囊制剂。观察其对肉仔鸡生产性能、免疫器官指数和血液生化指标的影响。结果表明,日粮中添加益生菌、黄芪多糖、合生元和微胶囊制剂均能显著提高肉仔鸡的增重(P<0.05),降低其料肉比(P<0.05);未发现微胶囊组与其他试验组增重有显著差异,但微胶囊组料肉比与其他试验组相比在0.05水平上差异显著。试验期间,各组鸡生长发育正常,未见器官异常,试验组免疫器官指数明显高于对照组(P<0.05),28 d微胶囊组免疫器官指数均高于其他试验组(P<0.05)。试验组血清总蛋白和α-淀粉酶含量较对照组升高(P<0.05),其中微胶囊组血清总蛋白含量较对照组在0.01水平上显著升高;试验组血糖含量均较对照组降低(P<0.05)。

288 Aiweiyin chicks were randomly divided into 6 groups with 4 replicates （12 chicks per replicate）. The basic diet of the 6 groups was the same and treatments were as follows： A without APS and PM, B with PM.Ⅰ, C with PMⅡ, D with PM and APS, E with APS and F with Mierocapsule. The effect of Microcapsule of Profitable Microbe and Astragalus Polysaccharide on Growth Performance, Immune organ index and Blood biochemical index of Chicks were observed. The results showed that：All of APS, PM, the compounds and Micrecapsule could significantly increase Average Growth Performance （ P 〈 0.05）, lower the feed/growth decrease significantly（ P 〈 0.05）. There was no significant difference of growth Performance between Mierocapsule and other experiments,but the feed/growth was significantly lower than other experiments. In experimental stage, all chicks growth and development were normal without organ abnormally. Compared to the eofitml group, immune organ index of trial groups were higher（ P 〈 0.05）.In the 28^th, Microcapsule group was significant higher than other groups（ P 〈0.05）. Blood biochemical index indicated that trial groups of serum total protein and amylase conent were higher than control group（ P 〈 0.05） ,but serum glucose is lower than control group（ P 〈 0.05）. Microcapsule group of serum total protein was significant higher than control group（ P 〈 0.01）.
