The influence of the genotype on milk yield, fat and protein content in the milk of cows of Ukrainian selection has been established. The highest levels of milk productivity traits were expected from animals with the CT genotype for the LEP gene, AA for the CSN3 gene, CC for the TG5 gene, and AA and BB for the Pit-1 gene. But at the same time, milk obtained from cows with CSN3 BB genotype were characterized by the best cheese suitability. The effect of the homo or heterozygous state of BLG on the signs of milk production was less noticeable, and the homozygous TT genotype for the TG5 gene was not found in any of the studied breeds. The results obtained can be used in the practical work of breeding farms along with traditional methods of selection, control and preservation of the genetic diversity of specific herds at an optimal level © 2022, Online Journal of Animal and Feed Research.All Rights Reserved. date: 2022-09-30 publication: Online Journal of Animal and Feed Research volume: 12 number: 5 publisher: Scienceline Publication pagerange: 302-313 id_number: 10.51227/ojafr.2022.41 refereed: TRUE issn: 2228-7701 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85140608960&doi=10.51227%2fojafr.2022.41&partnerID=40&md5=87fce75a9385a476a845f8dc84750921 j_index: scopus citation: (2022) CONNECTION BETWEEN GENE MARKERS WITH MILK PRODUCTION TRAITS OF UKRAINIAN DAIRY COWS.
