The experiment aimed to explore the effect of Banqi powder and Banqi powder fermented by probiotics on growth performance of animals.60 Weaned Piglets at the 28 day age were selected as animal models and were randomly divided into 3 groups.Weaned Piglets were respectively fed with the experimental diets supplemented with 0.5%Banqi powder fermented by probiotics,0.5%Banqi powder.The piglets were fed for 28 days.On the 7th,14th and 21st day,28th,blood sample was collected from the front cavity vein of each pig.The number of red blood cells and lymphocytes,the content of hemoglobin and other biochemical indicators in the blood were detected.The growth performance indexes such as diarrhea rate,daily gain and feed weight ratio of piglets were calculated.E.coli and lactobacillus were counted by plate counting method.The results showed that Banqi powder fermented by probiotics and Banqi complex could significantly increase the number of red blood cells,lymphocytes and hemoglobin content in the blood of piglets,could significantly reduce the diarrhea rate and mortality,increase the daily gain of piglets(P＜0.05).The number of intestinal lactobacillus of Banqi powder fermented by probiotics was significantly higher than that of Banqi power and control group(P＜0.05).The number of intestinal E.coli was reversed(P＜0.05).In general,Banqi complex has a good effect on improving the growth performance of piglets and reducing their diarrhea rate and mortality.
