A functionally significant element in ensuring homeostasis of the internal environment of an animal organism is platelets. The state of their activity greatly influences the rheology of blood in small vessels and, thus, the metabolism in tissues. It becomes clear that the process of growth and development of piglets at any age substantially depends on the level of their activity. In this regard, the assessment of agerelated changes in platelet activity in piglets during their early ontogenesis is of great importance. In the work performed, it was found that in piglets during the dairy and vegetable nutrition phase there is an increase in the adhesive, aggregation and secretory properties of platelets. The leading cause of these changes can be the enhancement of receptor processes and activation of the work of post-receptor mechanisms of information transfer in platelets. This is noted in piglets during the milk-plant nutrition phase simultaneously for both strong and weak aggregation inducers. The growth of platelet activity in piglets found during the observation period apparently was due to the intensification of thromboxane generation in platelets as a result of the increased activity of their cyclooxygenase and thromboxane synthetase, as well as an increase in the secretion of ADP molecules from them. The increase in the severity of the hemostatic properties of platelets in piglets during the milk-plant nutrition phase seems to be a serious regulator of their microcirculation and metabolism processes in any environmental conditions.
