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）.
