After birth, calves develop an increased ability of platelets to aggregate. At the same time, during the newborn phase, the level of inactive platelets in the blood of the Yaroslavl breed calves slightly decreases. The total intravascular activity of platelets in their blood during the study increased by 10.4%. The number of various platelet aggregates suspended in the blood of calves during the observation showed an upward trend. This was caused by an increase in their platelet thromboxane synthesis, an increase in the number of mobile adenosine phosphates in platelet granules and an increase in actin and myosin levels in them. As a result of the study, it becomes clear that for the Yaroslavl breed calves during the first 10 days of life, an increase in the severity of platelet aggregation and secretion is characteristic. Apparently, this helps to create optimal conditions for them to realize hemocirculation and metabolism, and therefore for the successful growth of animals of this breed.
