Reindeer breeding is a traditional branch of animal husbandry in the Republic of Sakha (Yakutia). In the Republic, this industry, along with horse breeding, has a number of advantages over other areas: year-round keeping of animals, adaptive qualities to local climatic conditions, unpretentiousness to forage conditions, etc. At the same time, there are a number of factors hindering the development of reindeer husbandry, such as funding, poor breeding work, predators, limited food resources in winter, blood-sucking insects, brucellosis, etc. The scientific work was carried out on the basis of the Municipal Unitary Enterprise "Borogonskoye" of the Bulunsky Ulus of the Republic of Sakha (Yakutia). The generally accepted research methods in reindeer breeding were used: appraisal and analysis of accounting data. The evaluation of animals was carried out in September - males and in October - females and young animals. Animals were graded during autumn corralization. Data on the structure of the herd are presented, as well as a long-term plan for the development of the enterprise. It was found that the conformation indicators of the animals of all herds did not differ significantly, which is explained by the active exchange between the herds. It has been established that starting from 2017, the main breeding stock has increased from 48%, 2018 - 55%, 2019 - 53% and accordingly in 2020 to 55%. Thus, a positive trend has been established in the structure of the reindeer herd.
