0
()
摘要:
本项研究结果表明:原麝的胃肠形态位置与羊的相似。麝胃属复胃,分瘤胃、网胃、瓣胃和皱胃。原麝瘤胃的后腹盲囊明显大于后背盲囊,瘤胃柱仅前柱较发达;网胃小房的皱褶低如线状,房底缺次级皱褶;瓣胃页有24片,不分级;皱胃含有腺体。皱胃旋褶有17片。原麝肠的特点是在回肠乳头的腹侧有一憩室,内有由集合淋巴小结形成的Peyer氏斑(板);结肠近袢卷曲成圆盘状。

PRIMARY STUDY ON MORPHOLOGICAL FEATURES OF STOMACH AND INTESTINE OF PROTOMUSK-DEER,MOSCHUS MOSCHIFERUS PALLA
()
Abstract:
Morphological features of the stomach and intestine of protomusk-deer,Moshus moschiferus Palla, were studied. The results are as follows: The morphological feature and position. of stomach of the protomusk-deer is similar to that of sheep. It consists of 4 parts,rumen, reticulum,omasus and abomasum. Only the mucous membrane of the abomasum containsglands, The posterior ventra blind sacs of the rumen is obviously biggerthan posterie ventra blind sacs and the coudition is very pronounced ascompared to all the pillars of the rumen. The cells of reticulum do not havesubdivided smaller folds. There are 24 laminae in omasum subdivided and 17 spiral flods in abo-masum. The intestine of proto-musk-deer is characterised as follows: Beneathit is a blind paunch, or diverticulum in which there is a peyers gland (Nodulilymphtici aggregati) on the ventra of ileum papilla. The proximals ansa ofcolis is arranged in double elliptical coils between the layers of the mesentery.
