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.
