| 摘 要： | 从不同猪场收集 1 2头大约克核心群公猪女儿的相关资料 ,利用BLUP法对 2 1日龄窝重进行遗传评估。结果表明 3个世代公猪的 2 1日龄窝重育种值分别为 55 71kg、 56 90kg和 57 65kg,呈上升趋势。对各世代环境效应的估计表明 ,A、B、E 3个场的环境条件逐步改善 ,而C、D两场有待加强 |

| Abstract: | The records of 21d litter weight of 12 Yorkshire boars from 5 breeding farms were genetic evaluated by the method of BLUP.The breeding values of 21d litter weight of first three generations were 55 71,56 90 and 57 65 kg respectively.The results showed that the genetic effects were positive,and the environment effects of farm C and D were not better while farm A,B and E improved. |
| Keywords: | Yorkshire boars BLUP 21d litter weight genetic evaluation |
