The growth dynamics and meat productivity of young stock of aboriginal horses bred in different natural and climatic zones of the Republic of Tyva were studied. The superiority of animals of the central forest-steppe zone over the peers of the southern dry-steppe zone in terms of live weight, absolute, average daily and relative increase in live weight during all age periods, slaughter parameters and morphological composition at the age of 30 months has been established. The advantage of young stock of the southern dry-steppe zone is established only by the content of first-class cuts in the varietal composition of carcasses. Aboriginal horses of the Republic of Tyva, bred in different climatic zones, combine good growth rates and high meat productivity. It is recommended to carry out the rearing of young stock with feeding in the summer months and subsequent sale at 30 months of age, which will increase the production of horse meat. Key words: horses, growth, live weight, horse meat, carcass, morphological composition.
