摘　　要：根据BLUP原理,利用甘肃省皇城种羊场2000-2003年共4610只绵羊的出生重、断乳重和周岁重数据资料,对绵羊早期生长性状进行不同模型的比较分析,筛选出在西北生境条件下,估测肉用绵羊各性状的动物模型。In this study, according to principle of best linear unbiased prediction （BLUP）, used birth weight, weaning weight, and yearling weight data, which had been collected from 2000 to 2003 at sheep farm of Hangchen in Gansu province , screened suitable ar.irnal models that can predict primordial growth traits of mutton sheep under specially ecological condition of the northwest of China.

关 键 词：BLUP 模型 绵羊 早期生长性状
