[Method] Diarrhea piglets were randomly grouped, and the clinical prevention and treatment effects of Shenwudi oral liquid were observed. Meantime, the effects of Huangzhi oral liquid and levofloxacin mesylate and sodium chloride injection were determined and compared with that of Shenwudi oral liquid. Shenwudi powder was added into the specific feed of weaned piglets at the dose of 5 g/kg, to observe its diarrhea prevention and growth promotion effect on weaned piglets. Compound amoxicillin powder was added in drug control group at the dose of 0.3 g/kg; no drug was added in blank control group. [Result] The cure rate of sucking piglets by Shenwudi oral liquid was 88.57%, and its protection rate was 100%; the cure rate of weaned piglets by Shenwudi oral liquid was 90.00%, and the total effective rate was 95.00%; the protection rate of weaned piglet diarrhea by Shenwudi powder mixing feed was 100%, and the average daily feed intake on the 42^（nd） day was extremely higher than the blank control group（P〈0.01）. [Conclusion] Shenwudi oral liquid can be used for prevention and treatment of sucking piglet diarrhea.Meantime, Shenwudi mixing feed has good prevention effect and significant growth promotion effect on weaned piglet diarrhea.展开更多
