Effects of Lactobacillus acidophilus Isolated from Brioler on Mucosal Immunity-Associated Cells in Small Intestine of Broiler
This current study was conducted to investigate the effects of Lactobacillus acidophilus on the number of mast cells and goblet cells of intestinal mucosal in Yellow broiler.A total of two hundreds 1-day-old broilers were randomly divided into five groups,and each group cinsisted of 4 replicates with 10 briolers each.The treament group Ⅰ was the control group,which fed with the basal diet;treament group Ⅱ,Ⅲ,Ⅳ,Ⅴ was fed with 5,10,15 g/kg Lactobacillus acidophilus and 20 mg/kg aureomycin in the basal diet,respectively.The results showed as follows:Compared with the control group,the number of the mast cells and goblet cells in small intestine in group Ⅳ increased significantly (P＜ 0.05),and the number of the mast cells in small intestine in group Ⅱ,Ⅲ was increased (P ＞ 0.05),while the number of the mast cells from jejumum to ileum in group Ⅴ significantly decreased (P ＜ 0.05).Compared with the control group,the number of the goblet cells in small intestine in group Ⅲ was significantly increased(P＜0.05),while that of group Ⅱ was increased insignificantly(P＞ 0.05),and that of group Ⅴ was significantly decreased(P＜ 0.05).The results indicate that the supplementation of lactobacillus acidophilus at 15 g/kg could signicantly increase the number of mucosal immunity-associated cells in small intestine of broilers.
