对敖汉细毛羊早期性状遗传参数估计的研究

摘要

The genetic parameters of early traits of Aohan fine wool sheep were analyzed by using BLUP model and MTDFREML method. The heritability of birth weight, weaning weight and yearling weight was obtained and the estimated genetic parameters were discussed.%运用动物模型BLUP法（最佳线性无偏预测法）和MTDFREML法（多性状非求导约束最大似然法）对敖汉细毛羊的早期性状进行了分析，得出了初生重、断乳重和周岁重的遗传力，并就遗传参数估计结果进行了讨论。
