Breeding quality control of Tuvan sire-stallions

The purpose of the study is to analyze breeding stallions of the Tuvan breed. Objectives: to identify typical stallions of the Tuvan breed that meet the breed standard; to distribute of stallions by class. The evaluation of the breeding qualities of the horse stock was carried out in accordance with the "Methodological recommendations on the procedure and conditions for the evaluation of breeding horses of the Tuvan breed", developed by the All-Russian Research Institute of Horse Breeding. During the expedition period (2018-2020), a total of 98 farms of all categories of 10 municipalities of the republic were covered (Erzinsky, Tes-Khemsky, Piy-Khemsky, Bai-Taiginsky, Dzun-Khemchiksky, Kaa-Khemsky, Kyzylsky, Tere-Kholsky, Chedi-Kholsky and Ovyursky kozhuuns). In total, more than 11 thousand horses of the Tuvan breed and their crosses were examined and analyzed. Of these, 4,864 horses of the Tuvan breed are included in the register, together with stallions, mares, young animals and geldings. The results obtained led to the conclusion that the number of purebred Tuva horses remained relatively small (less than 10% of the total population), in the horse breeding farms of the Republic of Tyva, the largest part (about 70 %) of animals belong to the 1st and 2nd class, and only 21 % of stallions are elite. It should also be noted that the largest number of elite class stallions are in the herds of Tes-Khemsky (19 heads, or 25.4 %) and Erzinsky (14 heads, or 21.5 %) Districts, but at the same time quite a lot of stallions of 1th and 2nd grades. The Bai-Taiginsky District has a very low level of stallion class.
