Abstract. The aim of the research was to genetically describe the cattle herd containing Hereford cattle (n = 141) and Limousin cattle (n = 161) based on the polymorphism in the 12th exon of the gene coding for insulin-like growth factor I receptor (bIGF1R/e12/MspI) and an attempt to estimate the potential relation between genetic variants and selected meat production traits features. The identification of the genotypes of particular individuals was carried out with PCR-RFLP. The most common genotype in the analysed herd was GG. There were no individuals with the AA genotype found. The statistical analysis revealed that the GG genotype was correlated with higher values of the analysed features compared to heterozygotes. The differences were statistically significant in most cases.
