| 摘 要： | 繁殖性状是奶牛生产的重要经济性状。繁殖性状属于数量性状,受多基因的调节和环境的影响,并且遗传力低(一般不到0.05)。采用传统的选择方法提高奶牛繁殖力很难奏效,而基因组学的发展为有效提高繁殖力提供了可能。介绍了繁殖性状的遗传变异、繁殖性状与产奶量的关系,传统育种和基因辅助育种策略,奶牛繁殖的功能基因组学和基因组选择的研究进展和发展前景,特别是基因组和蛋白质组学的研究有望提高遗传选择的效率,预计在不久的将来,能对改善奶牛的繁殖性能发挥重要作用。 |

| Abstract: | Reproductive traits are of significant economic importance in dairy cattle production.Reproductive performance of dairy cattle has declined over the past decades.Poor fertility of dairy cattle has been causing a lot of economic losses.These traits are quantitative traits regulated by multi genes and largely influenced by the environment.These traits have a low heritability,usually below 5%.It is not very effective to improve the reproduction performance by conventional breeding strategies.However,the develo... |
