The examination of 34healthy piglets fed with plant nutrition showed the decrease of the amount of lipid peroxidation products in their blood against the increase of their plasma antioxidant potential activity. There was found the increase of anti-aggregatory activity subscript range of the vascular wall with all the tested inductors and their combinations against the background of low levels of healthy piglets' endotheliazitemia. In the gradual increase of PGI2 synthesis and NO action in the blood vessels the aggregation inductors invariably do not influence the platelet receptors. That depends on the adequacy of regulation of fibrinogen receptors expressiveness by the vascular wall. It is stated that the A2 phospholipase activity regulating the withdrawal of the arachidonic acid from phospholipids is rather low in that process.

piglets, phase of plant-based feeding, early ontogeny, anti-aggregation, vascular wall, lipid peroxidation.
