本研究利用乳酸菌制剂对犊牛腹泻进行防治研究。结果显示，168头新生健康犊牛经15d饲喂试验，乳酸菌制剂组犊牛腹泻率为14.29%，而对照组腹泻率大于试验组2倍（29.76%）。乳酸菌制剂组腹泻犊牛无死亡现象，而对照组腹泻犊牛死亡率为3.57%；27头腹泻犊牛饲喂乳酸菌制剂治疗5d后腹泻率由100%下降为3.70%，腹泻治愈率达到85.19%；及早饲喂新生犊牛乳酸菌制剂可有效防治犊牛腹泻。结果表明，乳酸菌制剂可有效防治犊牛腹泻，避免犊牛因腹泻而死亡，可作为防治犊牛腹泻的微生态制剂推广应用。

A total of 168 healthy and newborn calves were divided into 2 groups randomly, and the experimental group feed LAB for 15 days. The results indicated that the diarrhea rate of the experimental group was 14.29%, compared to 29.76% in the control group. And the death rate of the control group was 3.57% with none death in the experimental group. In another group, 27 calves with diarrhea were treated with LAB for 5 days, the diarrhea rate decreased from 100% to 3.70% and the cure rate increased from 0 to 85.19%. Besides, the newborn calves were treated with LAB can prevent diarrhea effectively. Results indicated that LAB can prevent calves diarrhea and decrease the death rate of calves. Therefore, LAB can be used widely as probiotic to prevent and cure diarrhea.
