【 摘 要 】

Yaks are unpretentious and extremely hardy. They have a well-developed sense of smell, thick hair which helps them endure harsh climatic conditions. They can live in high mountains and hilly steppes. The aim of the article is to assess adaptive properties of yaks based on morphological and biochemical studies of blood samples and immunogenetic certification by blood groups. Cattle breeding is successfully developing in the Transbaikal Krai. However, yak breeding is a new activity. In 2015, 53 breeding yaks were purchased in the Oka district of the Republic of Buryatia and exported to the Transbaikal Krai. The experimental studies on blood of transported animals identified the high content of leukocytes and the high level of hemoglobin. The lymphocyte, monocyte and red blood cell indicators were within the norm. The calcium content decreased by 0.17 mmol/l. The ratio of calcium to phosphorus was 1: 1.8. The protein content was 72.35 g/l, alkaline reserve - 51.8 v%. The indicators were within the norm. While determining the frequency of individual blood antigens, it was found that the most frequent groups were as follows: J'-52%, X2 - 50%, Z - 49%, D'- 48%, A2 - 47%, V - 32%, G2 - 28%, F - 26%, E - 23%, O2 - 22%, P - 20%. In new conditions, the Oka yaks have high adaptive properties and productive qualities.
