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...
