摘　　要：用组织切片方法观察研究了不同饲养条件下,8只8～9月龄的阿尔巴斯绒山羊瘤胃粘膜的组织学变化.光镜观察结果表明:瘤胃的黏膜层内无黏膜肌层;瘤胃黏膜上皮的角化层以干草羊的最厚,其次为放牧羊,最薄的是青草羊.上皮细胞的形态:放牧羊中间层是多角形,基底层是矮柱状,细胞排列整齐;青草羊和干草中间层和基底层不一致,有圆形、椭圆形,细胞排列紧密,而且不整齐.瘤胃胃壁乳头的发达程度以干草羊的最高,其次为青草羊,最矮的是放牧羊.Histological changes of 8 eight to nine months old Aerbasi cashmere goats rumenal mucosae under different raising conditions have been studied with histology - sliced ways, The results of LM observing ： The epithelium horny of rumenal mucosa is thickest in hay - raised goats （ i. e. H）. second in grazed goats（ i. e. G1 ） and thinnest in green - grass - raised goats （ i. e. （;2）. The morphologyof epithelium eel1 with polyangle shape in the middle layers, short pillars shape and lined tidily in the stratum basale of G1 ,it is different in H and （;2 with circle and oval shape cells and lined tightly but untidily in the middle layers and stratum basale . The papil/ae of rumenal wall is the most well -developed in G1 ,second in G2 ,lowest in H.
