Yak production is one of the main leading branches of agriculture of the Republic of Tyva and is inseparably linked with the history of the Tuva people. In cultivation yaks in the republic the people have been engaged rather for a long time, it is possible that from ancient times. Today in Tyva the young growth of the yak is studied not fully. Therefore the materials presented in the study on the research of interior features of the Tuva and Buryat yaks raised in the conditions of the Republic of Tyva and the Republic of Buryatia are actual. The research objective was studying of indicators of blood of young growth of the yaks bred in the Republic of Tyva and their comparison with blood tests of yaks of the Republic of Burya-tia. Animals were in identical conditions of high-lands. The Blood of the yaks bred in basic farm of Federal public budgetary scientific institution "Tu-va Research Institute of Agriculture" (TRIA) the state unitary enterprise (SUE) "Bai Tala" of the Bai-Tayginsky kozhuun (area) of the Republic of Tyva was studied. The Blood was taken from a jugular vein from 10 heads of yaks’ young growth of the Tuva population by standard technique in the laboratories of Siberian research institute of animal husbandry (SRIAH). Animals’ blood and serum of blood served as material of researches. For comparison the indicators of blood of yaks’ young growth of the Republic of Buryatia which were earlier investigated by I.A. Kalashnikov and B. D. Nasatuev in 2010 were used. It was defined that in the blood of Tuva yaks the amount of he-moglobin was 1.23 times less in comparison with Buryat animals. The biochemical analysis of young growth of Tuva and Buryat yaks showed that Tuva yaks had the content of phosphorus and alkaline reserve more, to that of Buryat in 1.81 and 1.80 times respectively. In other indica-tors of blood no essential difference was ob-served. According to the obtained data, hemato-logic and biochemical indicators of young growth of yaks of the Republic of Tuva population char-acterize their physiological feature in connection with fitness to severe climatic conditions of the Republic of Tyva.
