八点黑獭兔消化器官形态结构的研究

Study on Morphosis of Digestive Organ of Eight Dot Black Rex Rabbits

分别对30～40日龄、60～90日龄、120～150日龄、180日龄以上4个阶段八点黑獭兔消化管的长度进行测定并对其有关结构进行观察描述。结果显示:40～90日龄期间消化管处在不断的生长发育中,并研究发现结肠狭窄部(长度4～5cm),回盲口与盲结口分开,直肠长度5～6cm,胃容积的大小与供料多少有密切关系。研究结果为我国家兔解剖学补充了新的内容。

Length of eight dot black Rex digestive tube were respectively measured at 30-40 days, 60-90 days, 120-150 days and above 180 days, and morphosis were described. The results indicated that digestive tube were continuously growing and developing from 40 to 90 days when rabbits accommodate environment, feeds and breeding administration. This research also shows the relationship between the volume of ventriculus and feeding amount. It will supply new content for rabbit anatomy.
