Abstract

During the final phase of early ontogenesis in calves, there is a low activity of lipid peroxidation, pronounced antioxidant protection of platelets, an increase in the intensity of the actin-myosin complex, a significant content of adenosine phosphates in their granules and their intensive secretion under conditions of platelet activation. In calves during the phase of plant nutrition, there was a tendency to increase the hemostatic capacity of platelets, assessed in vitro and in vivo. A certain increase in platelet aggregation and secretion found in calves during the phase of plant nutrition is apparently caused by regular age-related changes in the implementation of post-receptor processes in their platelets, which ensure an increase in their hemostatic characteristics in the conditions of completion of growth and development of their body.
