摘　　要：为了探讨体液免疫在鸡球虫病中的作用,通过制备柔嫩艾美尔球虫(E.tenella)特异性高免卵黄抗体,检测卵黄抗体在鸡盲肠中的代谢规律,对E.tenella进行体内外抑制和杀灭实验,观察特异性高免卵黄抗体对E.tenella的作用。结果表明:(1)口服的卵黄抗体在鸡消化道较稳定;(2)口服卵黄液可使感染E.tenella鸡的死亡率降低33.34%,增重率和抗球虫指数分别提高39.19%和73.50;(3)特异性高免卵黄抗体对E.tenella的子孢子具有明显的溶解和致弱作用,但对卵囊的孢子化速率和孢子化球虫卵囊的致病性没有明显影响。In order to study the characteristics of humoral immunity on E. tenella, specific vitelline antibody of E. tenella was prepared. The metabolic pattern of vitelline antibody in cecum was determined. With the internal and external restraining and killing experiment of E. tenella, effects of specific high immunized vitelline antibody on E. tenella were examined. The results showed： （ 1 ） The vitelline antibody in alimentary tract is steady. （2） Anticoccidial index（ACI） increased by 73.50, rate of weight increased by 39. 19 % , mortality decreased by 33.4 % in chickens inoculated with E. tenella by administering vitelline antibody. （3） Vitelline antibody has significant dissolving and weakening effect on sparozoite, but it has no effect on the speed of sporation of E. tenella, and pathogenicity of sporulated oocysts.
