Abstract: To search the molecular markers that are associated with mastitis and to provide a theoretical basis for the Holstein cattle breeding and disease resistance, the polymoprhisms of Nramp1 gene in 303 Holstein cattle in Ningxia were detected by the PCR-SSCP technique and the effect of Nramp1 gene c.200C>G locus mutation on milk traits and milk yield was analyzed using a general linear model. The results showed that there was a significant relationship between Nramp1 gene c.200C>G locus mutation and milk fat, milk yield and somatic cell score at the probability level of 0.05 or 0.01. Therefore we can put the site as cattle somatic cell score, daily milk yield measurement and daily milk fat genetic markers in Chinese Holstein.

Key words: Holstein cattle, Nramp1 gene, genetic polymorphism, milk traits, milk yield
