Experiments were carried out to apply oral vaccination to newborn pigs against transmissive gastroenteritis on a stationary swine breeding complex at the time when the disease assumed an acute course and on newly infected farms. Used was an attenuated strain an hour prior to allowing the pig to suck. It was found that such vaccination approach was innocuous. It proved effective when applied at the moment of birth both on the infected (stationary) farms and in the new foci of infection--morbidity and mortality were lowered and the body development of pigs was improved. Such vaccination was shown to produce also an antiepizootic effect if systematically used on stationary farms--clinically, there were no new epizootic outbreaks of the diseases.
在一个固定的养猪场以及新感染的农场中，当传染性胃肠炎呈急性病程时，开展了给新生仔猪口服疫苗以预防该病的实验。在仔猪吮乳前一小时使用了一种弱毒株。结果发现，这种疫苗接种方法是无害的。事实证明，在出生时对受感染（固定）农场和新的感染疫点进行这种接种是有效的——发病率和死亡率降低，仔猪的身体发育得到改善。如果在固定农场系统地使用这种疫苗接种，还显示出具有抗 epizootic 作用——临床上，没有出现该疾病新的 epizootic 爆发。 （注：epizootic 这个词在中文里没有完全对应的词汇，这里保留英文未翻译，可根据上下文灵活处理，比如可解释为“动物流行病的”等）
