[ Method] Piglets suffering from white scour were orally given the common melastorna herb decoction and norfloxacin, respectively. [ Result] After the weaned piglets were gavaged medicines, the treatment effect of the common melastoma herb decoction was significantly different from that of norfloxacin ( P 〈 0.05), and the optimal dosage of common melastoma herb decoction was 20 ml per piglet for treatment. After the weaned piglets were given medicines added in feedstuff, the treatment effect of the common melastoma herb decoction was significantly different from that of norfloxacin (P 〈 0.01 ), and the optimum dosage of common melastoma herb decoction was 50 ml per piglet for treatment. The preventive effect of the common melastoma herb decoction was significantly different from that of the control group in 35-day'old piglets suffering from white scour ( P 〈 0.05), and the optimal dosage of common melastoma herb decoction was 15 ml per piglet for prophylaxis. To mix medicine in feedstuff was the preferred way for the diseased piglets having appetite. [ Cenclusion] The common melastoma herb decoction has treatment effects and preventive effects on white scour of piglets.展开更多

The strains were used to make autologous inactivated bacterins,and the bacterins were applied to multiple infected farms. The results showed that in the group of inactivated bacterins,the infected piglet number was less,the course of disease was shorter and the symptoms was milder. The piglet E. coli inactivated bacterins could significantly reduced morbidity of yellow and white scour of piglets,the preventive effects of E. coli autologous inactivated bacterins against yellow and white scour of piglets were much better than that of genetically engineered vaccines.展开更多
