YX106系杜洛克种猪有效精子数遗传改良

Genetic improvement of effective sperm count of YX106 series Duroc pigs

公猪在养猪生产中占据着最重要的位置,公猪的优秀遗传基因可通过精液快速传递到商品群中,从而快速获得效益。因此公猪精液的好坏关系着公猪的价值。在高成本的选育前提下,选育出1头精液品质优良的公猪具有重要的意义。研究将公猪精液品质指标加入到公猪选育性状中进行对比分析。研究结果表明:对公猪进行精液有效精子数选育可提高选育质量,正向促进公猪选育效果,提升种公猪利用效率。

The boars play the most important role in the both genetic improvement programs and commercial pig production.High quality genes of boars can be quickly transferred to the commercial group through artificial insemination,and thus gain economic benefi ts quickly.Therefore,the semen quality is essential to show the value of boars.Since pig breeding is a practice of high-costs,it is of great signifi cance to select boars with good semen quality.In this study,semen quality was treated as one of the target traits in a boar breeding program and the relevant improvement was analyzed.The results show that selecting boars effective sperm cells resulted in boars with both good production performance and high fertility,which improves the utilization of elite boars.
