Abstract. Cows of the Polish Holstein-Friesian black-white variety were tested to identify c.328G>A polymorphism in the FABP4 gene and g.422C>T polymorphism in the TG gene. Three different genotypes (GG, GA and GG) were identified in cows in the FABP4 gene, with the GG genotype (0.74) and wild type G allele (0.85) occurring most frequently. High frequency of the wild type C allele (0.815) was demonstrated also in the TG gene. While the TT homozygotes accounted for only 7% of the total numbers in the herd, the CC made up as much as 70% of the total. The impact of GG and GA genotypes in the FABP4 gene and of CC and CT in the TG gene on yield and composition of milk in the first 3 consecutive lactations of young cows was analyzed. No effect between the tested genotypes and milk performance traits has been demonstrated.
