[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

Piglets and feed were weighed weekly to calculate the average daily gain (ADG), average daily feed intake (ADFI), and gain: feed ratio (G:F). Four piglets per treatment were killed on day 21 postweaning to collect ileal and colon digesta for measurement of short-chain fatty acids (SCFAs), branched-chain fatty acids (BCFAs), lactic acid (LA), and ammonia (AM). In the digesta collected from the ileum and colon, piglets fed the HPa diet had the lowest concentration of volatile fatty acids. Additionally, the HP diet produced the highest concentration of BCFAs, while the LPpb diet produced moreacetic, propionic, and butyric acids than the HPa and HP diets. Piglets fed the HP diet had higher incidence and severity of diarrhea than piglets fed LPpb and HPa diets, and similar values were observed between these two groups. The second week postweaning was the most critical for diarrhea measurements;during the second week, animals had higher incidence and severity of diarrhea. Piglets fed the HPa and LPpb diets had similar ADGs, while those fed the HP diet had the poorest ADG. Similar results were observed with ADFI and G:F. A low-protein diet supplemented with probiotics changed the fermentation profile, reducing toxic metabolites, promoting gut health, decreasing the incidence and severity of postweaning diarrhea, and improving the performance of piglets.展开更多
