摘要： The experiment was conducted to investigate the effects of Lactobacillin in the mucosal immune function in duodenum of young broiler. A total of 300, 1 day old broiler chickens were randomly divided into five groups with four replicates per group and 15 chickens were in each replicate. The chickens in the control group (goup I) were fed with the basal diet, those in goup II were fed with basal diet supplemented with antibiotics and those in the rest groups (goups III-V) were fed with basal diet supplemented with 50, 100 and 200 mg kg(-1) lactobacillin, respectively. The experiment was lasted for 28 days. The intestinal villi height, the number of mucilage cells, intraepithelial lymphocytes, mast cells and SIgA positive cells were detected by the technology of histochemistry and immunohistochemistry. The results showed that the height of intestinal villus in group II, IV was significantly more than group I (p<0.01) but there was not significantly difference between group II and IV. The results also showed that there was more mucopolysaccharide positive cells and mucilage cells in group II, group III and IV compared with group I (p<0.05). Compared with group I, the number of intraepithelial lymphocytes mast cells and SIgA positive cell in group II and IV have noticeably increased (p<0.05). It is concluded that Lactobacillin added to broiler diet with 100 mg kg(-1) can improve the mucosal immune function in duodenum of young broiler.
