The purpose of this research was to study the morphological and biochemical parameters of Bay-Talsky type yaks bred in the Bay-Tal yak breeding enterprise located in the Bay-Taiga mountain range. The BayTal type yak was created on the basis of purebred breeding in the Sarlyk breed in 2021. 43 heads of yaks of 18 months of age were used as experimental animals, from which two groups of yaks were formed, of which 23 heads of a new intra-breed Bay-Tal type and 20 heads of yaks of the Sarlyk breed. Of the yaks indicated in this experiment, blood counts were previously studied only in yaks of the Sarlyk breed. We have conducted the study of morphological and biochemical parameters of the Bay-Tal type yaks for the first time. As a result of the study, it was revealed that the average values of blood parameters in yaks were within the physiological norm. Nevertheless, the Bay-Tal yaks showed a higher level of hemoglobin – by 9.8% (P<0.05), the content of erythrocytes – by 10.9% (P<0.05) and leukocytes – by 34.4% (P<0.01) compared with Sarlyk yaks. Along with morphological parameters, the yaks of the new Bay-Tal type are characterized by a high content of biochemical blood parameters: total protein - by 16.4% (P<0.05), urea – by 40.6% (P<0.01), cholesterol and glucose – by 60% (P<0.001). The results obtained are important for establishing the average population level of a number of morphological and biochemical blood parameters in Bay-Tal yaks.
