| 摘 要： | 采用动物模型DFREML，进行了性别对约克夏猪主要经济性状遗传参数影响的研究。结果表明：约克夏猪的主要经济性状的最小二乘平均值在公母猪之间有明显的差异（P＜0．05）；模型中同时考虑母体效应时得到的遗传力均低于没有考虑母体效应时的遗传力。将性别作为国家效应时的各性状间的遗传相关高于只考虑公猪时的各性状间的遗传相关，但低于只考虑母猪时的各性状间的遗传相关。

| Abstract: | Effect of sex on genetic parameters of main economic traits of Yorkshire pig was determined using DFREML animal model. The least squares means of the major economic traits for Yorkshire were statistically significant( P <0 05) in sex From the model, additive genetic heritabilities estimated when the maternal effect was included were all lower than when the maternal effect was not included. If sex was considered as fixed effect the genetic correlations of all traits studied were higher than in males while were lower than in females |
