摘要/Abstract

摘要： 以PCR-RFLP方法检测了BoLA-DRB3基因在荷斯坦奶牛中的多态性，并统计分析了产犊年季和BoLA-DRB3基因分别被RsaI和HaeIII酶切后的不同基因型对SCS及其它产乳性状的影响。结果表明，RsaⅠAD型的SCS显著高于RsaⅠEG型（P<0.05）。另外，年季和BoLA-DRB3被RsaⅠ酶切后的不同基因型对蛋白率和乳脂率的影响均达到了显著水平（P<0.05）。Hae III AB型个体的蛋白率显著高于Hae III AA型（P<0.05）。

Abstract: In this study, the restriction polymorphism of BoLA-DRB3 loci in Holstein was investigated by PCR-RFLP，and the effect of year-season of calving and different genotypes of BoLA-DRB3 loci respectively digested by RsaI and HaeIII was analysed. The results suggested that SCS in individuals of RsaⅠAD genotype were significantly higher than that in individuals of RsaⅠEG genotype（P<0.05）; and that season of calving and different genotypes digested by RsaⅠhad significant effects on protein and fat percentage at level of P<0.05 ; and that protein percentage in individuals of Hae III AB genotype were significantly higher than that in individuals of Hae III AA genotype（P<0.05）.
