The considers the research results of productive qualities and biological features of Tyvan short-fat tailed sheep breed depending on the season of the year and the breeding zone of the Republic of Tyva: mountain taiga-steppe, desert-steppe and dry steppe. The highest live weight was observed in sheep raised in the dry steppe zone. When studying the biochemical composition of the blood of sheep in the summer-autumn grazing period, the content in the blood of sheep of the compared groups of basic biochemical parameters is within the physiological norms. In the winter-spring period, when grazing sheep on rags of last year’s grass due to a deficiency in their diets of basic nutrients, the blood levels of animals of all groups of total protein, calcium and reserve alkalinity are below physiological norms.
