在商业条件下饲养的仔猪中，采用了一种免疫程序，包括腹腔内接种大肠杆菌灭活疫苗，然后口服，以减少与大肠杆菌病相关的损失。断奶前和断奶后的死亡率均降低。接种仔猪的死亡率是未接种对照组的一半，断奶后3周，接种组生产的猪的总重量比对照组高33%。
An immunisation procedure involving intraperitoneal followed by oral administration of a killedEscherichia colivaccine was used to reduce losses associated with colibacillosis in young pigs reared under commercial conditions. Mortality was reduced in both the preweaning and postweaning period. The mortality rate among vaccinated piglets was half that of unvaccinated controls and by 3 weeks after weaning the total weight of pigs produced was 33% higher in the vaccinated group than in the control group.
