摘　　要：阿尔巴斯绒山羊是内蒙古绒山羊中的优良品种，试验在研究了不同饲养条件下8～9个月龄阿尔巴斯绒山羊前胃形态学变化的基础上，进一步对不同饲养条件下1．5岁阿尔巴斯绒山羊瓣胃的形态学变化进行了研究。结果表明：阿尔巴斯绒山羊的瓣胃有最小瓣叶；瓣胃的大瓣叶上偶尔可见到次级瓣叶；在网瓣口处有明显的网瓣口括约肌。圈养条件下阿尔巴斯绒山羊瓣胃的容积（包括瓣胃大、小弯）会缩小；网瓣口括约肌的厚度会变薄；瓣胃瓣叶的高度会缩短。The Alpas cashmere goats are the excellent breed of Inner Mongolia. On the basis of the research on the manyplies morphology change of 8 to 9 month - old goats under different raising condition, the writer further researched on that of the 1.5 year - old Alpas cashmere goats. The result shows that the Alpas goats has the smallest folds of manyplies. Occasionally the 2rid tier of folds of manyplies could be found at the bigger ones. The constrictor could be seen clearly at the ora between the reticulum and the manyplies. When the Alpas goats are raised by pen, the capacity of their manyplies, including the big and small curve, will decrease. Under the same condition pen - raising, the constrictor at the ora between the reticulum and the manyplies will get thinner, and the height of the folds of the manyplies will decrease.
