摘　　要：应用组织切片技术对11～53日龄吉林白鹅小肠绒毛高度、绒毛宽度、隐窝深度和肌层厚度进行测定。结果显示,小肠各段绒毛高度及宽度随日龄增加整体上呈增长趋势,空肠绒毛最长,回肠绒毛高度、宽度在39日龄达到峰值,早于空肠和十二指肠。回肠隐窝深度11～53日龄随日龄增加而增加,十二指肠和空肠隐窝深度在39日龄达到峰值,39～53日龄变浅。小肠各段肌层厚度与日龄呈正相关,回肠的肌层厚度在46日龄达到高峰,十二指肠和空肠的肌层厚度在53日龄达到高峰。小肠各段绒毛高度/隐窝深度的比值随日龄增加而增加,53日龄时空肠的绒毛高度/隐窝深度的比值最高。The aim of this experiment was to determine the morphological changes of the small intestine of Jilin white geese.The height,width of the villi,depth of the crypts and muscle thickness were measured in 11-53 days of life.The results indicated that the height,width of the villi increased with the age.The villus height was the greatest in the jejunum.The villus height and width of the ileum peaked at 39 days of age,earlier than that of jejunum and duodenum.The crypt depth in the ileum increased during 11 to 53 days,whereas that in the jejunum and duodenum peaked at 39 days of age and then decreased during 39 and 53 days.The muscle thickness in the small intestine were positively correlated with the age of the geese.and the muscle thickness of the duodenum,jejunum,and ileum peaked at 53,53,and 46 days,respectively.The ratio of the villus height to the crypt depth（V：C）in all the small intestinal segments increased as the age,the V：C ratio in the jejunum is the highest at the age of 53 days.
