仔猪黄痢是由致病性大肠杆菌引起的急性传染病,发病早,病势急,发病率、死亡率都很高,尤以初产母猪所生仔猪为甚。长期以来多用抗生素等药物治疗此病,早期使用还有些效果,随着用药时间的延长,疗效逐渐下降。我们于1982年11月～1983年1月、1983年4月～7月分两阶段在新疆生产建设兵团石河子总场种猪场进行了促菌生治疗仔猪黄痢的试验。该猪场近三、四年来深受仔猪黄痢之害,病势有逐年加剧的趋向,经产母猪的仔猪黄痢发病率约为50％;而初产母猪 Piglet yellow dysentery is an acute infectious disease caused by pathogenic E. coli. It has early onset, acute illness, morbidity and mortality, especially for piglets born in primiparous sows. For a long time with antibiotics and other drugs to treat the disease, there are some effects of early use, with the extension of medication time, the effect decreased. In November 1982 ~ January 1983, April 1983 ~ July 1983 in two phases in Xinjiang Shihezi total production pig farms were boosted piglets yellow dysentery experiment. The pig farms in the past three or four years by the piglets yellow dysentery harm, the trend has increased year by year trend, the sow piglets born diarrhea incidence of about 50%; and primiparous sows
