摘　　要：大肠杆菌(Escherichia coli)是断奶仔猪腹泻最重要的原因之一,肠道微生态环境失调和不良的体外饲养环境是其诱发因素。本试验将64头体重相近、遗传基础相似的28日龄的断奶仔猪随机分为两组,与对照组不同的是试验组在发酵床上饲养,日粮中添加0.1%洛东酵素。结果表明:试验组能有效改善断奶仔猪肠道微生态平衡,同时提供良好的饲养环境,大大降低了腹泻率,对断奶仔猪大肠杆菌性腹泻具有明显的生物防治效果。Escherichia coli is one of the most important causes of postweaning diarrhea in pigs. Intestinal microecology envi- ronmental disruption and the environment of pig - raisin are the inducing factors. In this experiment, sixty four weanling piglets of twenty eight days old were divided into two groups based on the same weight and breeding by randomly. Different from control group,the experiment group was fed on fermenting bed with dietary additions of O. 1% ferment. The experiment result showed that it can improve both the balance of intestinal microecology environment and the environment of pigraisin, reduce the rate of diarrhea greatly; It had positive effect of biological control for E. coli diarrhea in weanling pig.
