摘　　要：对相同条件下饲养的不同生长阶段(出生、1周龄、2周龄、3周龄4、周龄、5周龄、6周龄、8周龄、12周龄、成年)獭兔进行屠宰,观察测定肠道绒毛和腺窝变化,以研究獭兔消化组织形态的发育规律。结果表明:獭兔小肠绒毛长度随周龄的增加而增加。断奶刺激降低绒毛长度,但断奶1周后基本恢复。石蜡切片观察发现獭兔小肠绒毛形态为指状。To determine the development of morphology shape of digestive tract, 150 Rex rabbits were slaughtered at newbroth, 1w, 2w, 3w, 4w, 5w, 6w, 8w, 12w and adult. The trial rabbits were fed in same condition, the morphology shape of digestive tract was determined and observed. The result indicated that the length of villus had increased with the ages. Weaning had decreased the length of villus and then villus was regenerated after weaning for 1 week. The villus morphology shape of small intestine was like finger observed in the paraffin section.
