Modulatory effects of Ginkgo biloba extract on duodenum _mucosal immunity of broilers
研究银杏叶提取物(EGB)对肉仔鸡十二指肠黏膜的免疫调节作用。将360只1日龄健康AA肉用母雏鸡随机分成5组,每组6个重复,其中1组为对照组,饲喂基础日粮;其余4组分别饲喂添加质量分数0.009%金霉素及0.15%,0.20%和0.25%EGB的日粮,试验期为42 d。分别于21和42 d取样,测定各组肉仔鸡十二指肠黏膜免疫球蛋白含量、黏膜免疫相关细胞数量和白细胞介素-2(IL-2)含量。日粮中添加质量分数0.20%,0.25% EGB可显著提高42日龄肉仔鸡十二指肠黏膜IgA、IgG、IgM含量(P0.05),提高十二指肠上皮内淋巴细胞、肥大细胞、杯状细胞数量和IL-2含量(P0.05),并...

Summary: | 研究银杏叶提取物(EGB)对肉仔鸡十二指肠黏膜的免疫调节作用。将360只1日龄健康AA肉用母雏鸡随机分成5组,每组6个重复,其中1组为对照组,饲喂基础日粮;其余4组分别饲喂添加质量分数0.009%金霉素及0.15%,0.20%和0.25%EGB的日粮,试验期为42 d。分别于21和42 d取样,测定各组肉仔鸡十二指肠黏膜免疫球蛋白含量、黏膜免疫相关细胞数量和白细胞介素-2(IL-2)含量。日粮中添加质量分数0.20%,0.25% EGB可显著提高42日龄肉仔鸡十二指肠黏膜IgA、IgG、IgM含量(P0.05),提高十二指肠上皮内淋巴细胞、肥大细胞、杯状细胞数量和IL-2含量(P0.05),并且作用效果优于金霉素组(P0.05)。日粮中添加质量分数0.20%或0.25% EGB,可增强肉仔鸡十二指肠黏膜免疫功能。
An experiment was conducted to investigate the modulatory effects of Ginkgo biloba extract (EGB) on duodenum mucosal immunity of broilers. Three hundred and sixty one-day-old healthy Arbor Acres female broilers were divided into five groups, each with six replicates. The first group was the control group and fed a basal diet, while the other four groups were fed the same basal diet supplemented with 0.009% aureomycin or 0.15%, 0.20%, 0.25% EGB. The experiment lasted 42 days. The contents of immunoglobulin, the numbers of mucosal immunity-associated cells and the level of interleukin-2 (IL-2) in duodenum mucosa were determined. Adding 0.20% EGB or 0.25% E |
