| 摘 要： | 母猪的繁殖性能是影响养猪业经济效益的重要因素，提高母猪繁殖性能也是种猪育种者和肉猪生产者追求的目标之一。母猪的繁殖力性状既是低遗传力性状，又是限性性状，用传统的选择方法选择效果不明显。本文通过查阅国内外有关文献，对猪繁殖力性状的特点、影响因素以及繁殖性状选择方法进行了总结，并就提高种猪繁殖性能方法的优缺点进行探讨。基因组选择为猪繁殖性能的选育提供了新的方法和思路。

| Abstract: | The reproductive performance of sow is an important factor affecting the economic benefits of pig industry, and improvement of reproductive performance is one of the goals for breeders and pork-producers. The reproductive trait of sow is not only a low-heritability trait, but also a sex-limited trait. So the selection effect is not obvious when the traditional selection methods are used. The characteristics, influencing factors, selection methods of porcine reproductive traits were summarized by consulting the relevant literatures and researches. And the advantages and disadvantages of these selection methods were discussed. Genomic selection is the potential selection method to improve porcine reproductive performance. |
