Of great scientific interest is the assessment of the functionality of platelets in dairy calves at the end of early ontogenesis. 44 healthy calves of the Kholmogory breed were observed, obtained from completely healthy cows after their 2nd-3rd pregnancy. During the observation period, the young animals developed an acceleration of the process of platelet aggregation in vitro. This was accompanied in calves by an increase in the number of activated platelets in the blood and the number of their aggregates of different sizes. An increase in the functionality of platelets occurred in calves during the phase of plant nutrition due to an increase in the amount of all adenosine phosphates, an increase in the synthesis of thromboxane in them, an increase in the content of actin and myosin in them, and an intensification of their self-assembly in the case of the participation of platelets in hemostasis. The increase in hemostatic capabilities noted in calves of the Kholmogory breed is of great importance for the success of their growth and development processes during the phase of plant nutrition.
