Abstract
The study analyzed the polymorphism of single nucleotide substitution A8232C, located in the 3’UTR region of the receptor of the oxidized low-density lipoprotein (OLR1) gene. The study was conducted in a herd of Polish Holstein-Friesian (Red-and-White strain) dairy cattle. Identification of genotypes of individuals was performed using PCR-RFLP. The study stated the following frequency of A8232C polymorphism alleles: A - 0.30 and C - 0.70. Statistical analysis showed that the AC genotype cows were characterized by higher milk yield, protein and fat and for fat yield, the difference was confirmed statistically (P≤0.05). The cows with genotype AA were characterized by the latest occurrence of first calving and the longest intercalving interval, but the results were not confirmed statistically.
