Abstract. The study involved 448 Black-and-White Holstein-Friesian cows. All animals came from one herd, they were kept in the same barn and in the same environmental conditions. Complete phenotypic data on the studied animals was collected. The aim of the research was to search for possible associations between SNPs in the CXCR1 and IL6 genes and mastitis. Identification of specific SNPs was possible due to the use of the PCR-ARMS method. Statistically significant associations were found between the analysed SNPs and resistance to mastitis and selected milk production traits.
