摘  要：
为了研究舍饲条件下绵羊瘤胃形态学上的发育特点,随机选取40、60、120、180、240日龄绵羊瘤胃进行容积、瘤胃相对容积以及瘤胃黏膜乳头高度、宽度和密度的测定。测定结果表明,瘤胃容积和瘤胃相对容积随着日龄的增加而增大,在60日龄后瘤胃容积随日龄增加显著(P<0.05),在120日龄前瘤胃相对容积增加显著(P<0.05)。瘤胃黏膜乳头高度和宽度随日龄增加而增大,瘤胃黏膜乳头密度在60日龄前随日龄增加而增大,在60日龄后随日龄增加而减少。瘤胃各部乳头形态变化的显著性差异不同。

摘  要：
In order to investigate the developmental characteristics of confined sheep rumen in morphology, the sheep aged 40, 60,120, 180 and 240 days were randomly selected respectively, and their rumen volume, relative rumen volume, and the height,width and density of papillae in mucosal layer of rumen were determined. The results revealed that the rumen volume and relative rumen volume of sheep was increased along with the increase of age in days; After 60-day-old, the rumen volume was increased along with the increase of age in days(P<0.05); Before 120-day-old, the relative rumen volume was significantly increased(P<0.05).The height and width of papillae in mucosal layer of rumen was increased along with the increase of age in days; Before 60-day-old, the density of papillae in mucosal layer of rumen was increased along with the increase of age in days; After 60-day-old,the density of papillae in mucosal layer of rumen was reduced along with the increase of age in days. The morphological changes of papillae in varied parts of rumen are different in significant differences.
