Summary. In Yakutia, the volume of meat production per capita in 2017 amounted to 37.1 kg or 59.4% of the annual consumption rate (62.5 kg). The creation and development of an independent industry of beef cattle breeding is very important in the republic. Since 2013, Kalmyk cattle have been imported into the republic. At the beginning of 2019, the number of beef cattle in Yakutia was 991 heads, among them – 457 cows (46.1%). In this connection, it becomes necessary to study the adaptive reactions of imported animals in a acute continental climate, severe and long winters with very low air temperatures.

It was established that the level of AST in the imported Kalmyk cattle was significantly higher than that of the Simmental cattle by 20.2% and amounted to 87.6 ± 2.84 units / l, which indicates a high activity of the digestive tract (P≤0,05). However, ALT activity was significantly lower than the physiological norm (P≤0.05). Moreover, the number of red blood cells and the level of hemoglobin in the blood are 21.2 and 9.93% higher than those of peers of the Simmental breed (P≤0.01).

It was revealed that young Kalmyk breed has a higher level of alpha and gamma globulins by 4.8 and 33.7% than that of peers of the Simmental breed. Thus, in conditions of acute continental climate of Yakutia Kalmyk calves had higher indicators of morphological and biochemical composition of blood than that of analogues from the Simmental breed. Such high hematology indices make it possible to adapt well in the harsh conditions of Yakutia.

Key words: beef cattle breeding, bulls, Kalmyk breed, Simmental breed, acute continental climate, adaptation of animals, total protein, albumins, globulins, AST, ALT, Yakutia.
