英文摘要：

To screen the best prescription for treating yellow and white scour of piglets, and to determine a reasonable drug dosage and the scope of indications. 478 suckling piglets diagnosed with yellow and white scour, were randomly divided into 6 groups, which were treated with 3 pre- selected prescriptions （ prescription I , II, and m ）, ofloxacin, norfloxacin and a combination of ofloxacin and norfloxacin, respectively. The effects of treating yellow and white scour of piglets with the preselected prescriptions and the control drugs were compared to screen the best traditional Chinese drug prescription. Each preselected prescription group was also divided into three groups according to the low, medium and high doses to determine a reasonable drug dosage with the preselected prescription, respectively. The applicabilities of the preselected prescriptions for different symptoms were investigated using the traditional Chinese veterinary drugs according to the characteristics of the disease, respectively. The results showed that the efficacies of Chinese veterinary drugs were better than those of the control drugs, and the recurrence rate of the former was significantly lower than that of the later. Among the three preselected prescriptions, the cure rate and total effective rate of the prescription I were 82.9 % and 84.7 %, respectively, which was significantly better than the others. The results indicate that the medium dosage of prescription I has significant effect on treating yellow and white scour of piglets, its cure rate and total effective rate were 88.9 % and 91.1%, respectively, which is significantly better than the other dose groups, and there is no recurrence after cure.
