骨调素基因多态性及其与大河乌猪繁殖性状相关分析的研究

 研究了骨调素基因对大河乌猪繁殖性能的影响。结果表明，大河乌猪初产活仔数、二产活仔数各基因型之间差异显著(P＜0.05)，其中，初产活仔数的基因型189/171/166/150与基因型189/171/150之间差异显著，二产活仔数的基因型166/150与基因型189/171，189/166之间差异显著；而初产的总产仔数、乳头数、初生仔重各基因型间差异不显著。骨调素基因型189/171/166/150和基因型166/150是有利基因型，骨调素可能是影响大河乌猪繁殖性状的侯选基因，可以作为提高大河乌猪初产活仔数和二产活仔数的遗传标记。

Study on Osteopontin Gene Polymorphism and Relevance Analyses between the Polymorphism and Reproductive Traits of Black Dahe Pig

In this paper,the effect of Osteopontin(OPN) gene on the Black Dahe pig reproductive performance was researched.The results indicate that the genotypes between the first number born alive and the second number born alive are significantly different(P<0.05),and the genotypes of the first number born alive between with 189/171/166/150 and 189/171/150 are significantly different,and the genotypes of the second number born between with 166/150 and 189/171,189/166 are significantly different.But the genotypes among the number born alive(NBA),teat number and weight at birth are not significantly.The genotypes of Osteopontin(OPN) gene with 189/171/166/150 and 166/150 are advantageous genotyp es.Therefore,Osteopontin(OPN) gene are likely to candidate gene infected to reproductive traits of Black Dahe pig.It can improve the first number born alive and the second number born alive on Black Dahe pig as genetic marker.
