Physiological features of platelet hemostasis in calves during the phase of plant nutrition, kept in the ecological conditions of central Russia

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.
