【摘要】 选用3种中草药配方,采用1%、1.5%、2%3个添加水平,进行9个试验组和1个对照组比较研究。对试验鸡的45 d免疫器官质量和T、B淋巴细胞进行检查,对不同日龄鸡新城疫(ND)和传染性法氏囊(IBD)的抗体效价、中性粒细胞吞噬功能和T淋巴细胞转化率进行检测。结果表明,试验组脾质量、法氏囊质量及T、B淋巴细胞相对数高于对照组(P<0.05),以配方B为最高,其次为配方A。试验组抗体效价、中性粒细胞吞噬率、吞噬指数和T淋巴细胞转化率高于对照组(P<0.05),其中ND抗体效价I、BD抗体效价20 d前组间差异不显著,34 d后组间差异趋于显著。54 d和126 d时,A、B、C 3配方中性粒细胞吞噬率和吞噬指数组间差异显著(P<0.05或P<0.01);T淋巴细胞转化率组间也存在极显著差异,其中配方A中的1组具有明显优势。重复试验结果基本相似。更多还原

【Abstract】 Three Chinese herbal formulations were selected and each fomulation was used at levels of 1%,1.5% and 2% respectively.Weights of immune organs,B-and T-lymphocytes numbers at 45 days of ages,antibody titers of ND and IBD,phagocytotic function of neutral granular cells and conversion rates of T-lymphocytes were measured.The results showed that weights of spleen and bursal,relative numbers of B-lymphocytes and T-lymphocytes in experimental groups were higher than those in control(P<0.05),particularly in prescription B group.Antibody titer of ND and IBD,phagocytosis rates and indices,conversion rates of T-lymphocytes in experimental groups were higher than those in control(P<0.05).The differences of antibody titer in different groups were not significant before 20d,and tented to be significant after 34 days of age(P<0.01).The differences of phagocytosis rates and indices at 54 and 126 days of age between groups were significant(P<0.05 or P<0.01).High significant differences of conversion rate of T-lymphocytes between groups at 54 and 126 days of ages were also found.Prescription A was better than B and C,among which group 1 showed more obvious effect.The results of repeated experiment were similar to that of the above.更多还原
