| 摘 要： | 仔猪大肠杆菌性腹泻病的致病过程主要与产肠毒素型大肠杆菌菌毛介导的粘附作用和产肠毒素密切相关，用禽菌毛抗原免疫产蛋母鸡制备卵黄抗体，在初生仔猪和断奶仔猪的人工感染实验中，口服卵黄抗体能降低腹泻程度和仔猪的死亡率；在商业性猪场的实验表明，卵黄抗体能降低提前断奶仔猪的腹泻发生率，并且有利于仔猪的增重，鸡卵黄抗体是仔猪大肠杆菌性腹泻病的一种新的防治方法，本文就国内外鸡卵黄抗体防治仔猪大肠杆菌腹泻的研究概况作了简要介绍。

| Abstract: | Diarrhoea of neonatal and post-weaning piglets strongl y related with t he fimbriae mediated adhesion and toxins producing ability of enterotoxigenic E scherichia coli (ETEC). Chicken egg-yolk antibodies against fimbriae of ETEC w ere used in some trial. In these trial orally administration of chicken egg-yolk a n tibodies reduced the incidence and severity of diarrhoea, and reduced the mortal ity of piglets, and increased liveweight gains. It is a new method to use chicke n egg-yolk antibodies in prevent and therapy piglets diarrhoea. This paper made a simple review in this field around the world. |
