The paper considers the features of the Yakut cattle, one of the ancient aboriginal breeds of cattle. The Government of the Republic of Sakha (Yakutia) pays special attention to this unique breed, which has prospects for its development. The main livestock is kept in a specialized enterprise for breeding Yakut cattle - GKP RS (Ya) "Yakut cattle". Currently, this company has 9 branches. In 2023, a department for fattening steers was established in the Amginsky district of the republic. The paper presents the results of fattening, which indicate the expediency of the meat direction for this breed of cattle. Undoubtedly, the preservation of a unique breed of Yakut cattle is possible only if it is competitive. It should surpass competitors in terms of dairy and meat productivity. And the enterprise GKP RS (Ya) "Yakut cattle" strives for this goal.

The republic is taking measures of state support for farms of various forms of ownership, which contribute to the preservation and increase in the number of Yakut livestock. Thanks to the measures taken over the past five years, the number of Yakut cattle in the State Enterprise of the Republic of Sakha (Yakutia) “Yakut Cattle” has increased by 2.5 times. 10 colors were identified, the main ones being black and motley - 43.3%, black - 21.4%, white and motley - 16.6% and others 18.7%. The article presents the results of a study of the genetic structure of Yakut cattle by the Gene pool state enterprise of the Republic of Sakha (Yakutia) “Yakut Cattle” (n=366). To study the population genetic structure of Yakut cattle, microsatellite analysis of 15 STR loci was used. In the three studied populations, the most variable loci are TGLA53 (11 alleles), TGLA227 and TGLA122 (8 alleles), and the least variable are BM1818, BM1824, INRA023 (3 alleles). The greatest genetic diversity was noted among the cattle of the Syuldyukar site. It was found that in the Yakut cattle populations of the “Tastaakh” and “Kylys” areas, the observed heterozygosity is higher than expected, the Fis index has a negative value. In the sample of animals from the “Suldyukar” site, the observed heterozygosity (Ho=0.598±0.045) is less than expected (He=0.607±0.035), and the Fis index has a positive value (Fis=0.022±0.035), which indicates a lack of heterozygotes and is confirmed by phenotypically lower diversity livestock color options.
