Abstract: To explore the effects of Xiaoshi Pingwei powder fermented by compound probiotics on the production performance and intestinal health of piglets，64 healthy weaned piglets with similar body weight were selected and randomly divided into 4 groups（16 piglets per group），namely the control group（group A），compound probiotics group（group B），Xiaoshi Pingwei powder group（group C），and Xiaoshi Pingwei powder fermented by compound probiotics group（group D）.They were fed a basal diet，basal diet+0.2% compound probiotics，basal diet+0.5% Xiaoshi Pingwei powder，and basal diet+0.5% Xiaoshi Pingwei powder fermented by compound probiotics，respectively，with a test period of 21 days.The results showed that compared with group A，the average daily feed intake of piglets in groups B，C，and D significantly increased by 3.53%，5.52%，and 6.48%，respectively；the average daily gain of piglets in groups B，C，and D significantly increased by 9.76%，11.92%，and 20.55%，respectively；the average feed⁃to⁃gain ratio of piglets in both groups B and C significantly decreased by 6.00%，while that in group D significantly decreased by 12.00%；the diarrhea rate of piglets in groups B，C，and D significantly decreased by 32.96%，39.41%，and 83.12%，respectively.Meanwhile，compared with group A，groups B，C，and D all significantly increased the apparent digestibility of nutrients such as dry matter，crude protein，crude fat，and calcium in the piglet diet，and the contents of copper，zinc，and manganese in the feces of groups B，C，and D were significantly reduced；the number of Lactobacillus in all segments of the intestinal tract of piglets in groups B，C，and D was significantly increased，while the number of Escherichia coli was decreased.In addition，groups B，C，and D all significantly increased the number of red blood cells，hematocrit，hemoglobin content，and hemoglobin concentration in the blood of piglets；furthermore，the intestinal villus height and the ratio of villus height to crypt depth of piglets were significantly increased，while the crypt depth was significantly decreased.In summary，both compound probiotics and Xiaoshi Pingwei powder can improve the growth performance，nutrient digestibility，intestinal health，and resistance of piglets，among which Xiaoshi Pingwei powder fermented by compound probiotics has the best effect，providing a reference for efficient and healthy pig breeding.

摘要： 为探究复合益生菌发酵的消食平胃散对仔猪生产性能及肠道健康的影响，选取64头体质量相近的健康断奶仔猪，随机分为4组（每组16头），即对照组（A组）、复合益生菌组（B组）、消食平胃散组（C组）和复合益生菌发酵的消食平胃散组（D组），分别饲喂基础日粮、基础日粮+0.2%复合益生菌、基础日粮+0.5%消食平胃散、基础日粮+0.5%复合益生菌发酵消食平胃散，试验周期21 d。结果表明，与A组相比，B组、C组、D组仔猪的平均日采食量分别显著提高3.53%、5.52%、6.48%；B组、C组、D组仔猪的平均日增质量分别显著提高9.76%、11.92%、20.55%；B组、C组仔猪的平均料重比均显著降低6.00%，D组则显著降低12.00%；B组、C组、D组仔猪的腹泻率分别显著降低32.96%、39.41%、83.12%。同时，与A组相比，B组、C组和D组均显著提高仔猪日粮中干物质、粗蛋白、粗脂肪和钙养分表观消化率，且B组、C组和D组粪便中铜、锌、锰含量显著减少；B组、C组和D组仔猪肠道各段乳酸杆菌数量均显著增加，大肠杆菌数量降低；B组、C组和D组均显著增加仔猪血液中红细胞数量、红细胞压积、血红蛋白含量和平均血红蛋白质量浓度；此外，仔猪肠道绒毛高度、绒毛高度/隐窝深度比值显著提高，隐窝深度显著降低。综上，复合益生菌和消食平胃散均可改善仔猪生长性能、养分消化率、肠道健康及抵抗力，其中复合益生菌发酵消食平胃散效果最优，可为生猪高效健康养殖提供参考。
