绵羊多胎性状的主效基因研究进展及在畜牧业中的应用

Research Advances on Exploring Major Genes for High Fertility in Sheep and Application in Animal Husbandry

绵羊多胎性状主要受主效基因的控制。研究绵羊多胎性状主效基因,不但能够阐明已了解的多胎羊生理和遗传机理,得出多胎性状遗传模式,而且有助于家畜的选种选育,提高绵羊繁殖力。文章综述了绵羊多胎性状主效基因国内外的研究进展以及在畜牧业中的应用,旨在为绵羊多胎品种的分子选育提供参考。

Fecundity trait of sheep is mainly genetically controlled by major gene. Studying on major gene of fecundity trait in sheep not only can reveal many physiological and genetic mechanisms of prolific sheep that have found, and determine the inheritance patterns of major gene of the trait, but also help selecting and breeding of livestock, improving fecundity of sheep as well. This review summarized the research advances on major gene of fecundity trait in sheep as well as application in animal husbandry both home and abroad in order to provide reference for molecular breeding of prolific cultivars in sheep.
