The aim of the work was to study the traits of dairy productivity of Holstein heifers with different genotypes of the paraoxonase-1 (PON1) gene. The research was conducted in 148 animals of Integrated Agricultural Production Centre “Stud farm named after Lenin” of Atninsky district of the Republic of Tatarstan. Genotyping of cattle was carried out by the PCR-RFLP method at the laboratory of the Department of Agrobiological Research of Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences. The results of allele and genotype calling of the PON1 gene showed that the study population is polymorphic and differs in genetic biodiversity. During the analysis of daity productivity, qualitative composition of milk and lactational activity, it was found that cow-heifers with the GG genotype of the PON1 gene were superior to animals with other genotypes in all the test parameters. Thus, it follows that the GG genotype of the PON1 gene has a positive effect on the economic characters of cattle, which can be used in breeding in the future.
