分析和非加权组平均法聚类分析显示组间具有差异性。两个品种绵羊
瘤胃菌群在门水平上组成相似，优势菌门均为拟杆菌门、厚壁菌门及变形菌门。对差异菌群进行 KEGG
功能预测，结果显示，双乾肉羊瘤胃微生物功能大部分高于小尾寒羊。从上述分析来看，双乾肉羊瘤
胃菌群种类及丰度均高于小尾寒羊，这可能导致了双乾肉羊饲料利用率更高。

Abstract: The purpose of this experiment is to investigate the ruminal microflora characteristics
and differences between Small-tail Han sheep(STH) and Shuangqian mutton sheep(SQ).6 STH
and 6 SQ were randomly selected, which were similar birth date,initial body weight and good
