Vascular Hemostasis in Heifers on Rearing

Medvedev Ilya Nikolayevich, Zavalishina Svetlana Yur’evna

Abstract


On investigation of 42 healthy black-and-white breed heifers on rearing the tendency for the decrease of acylhydroperoxides and thiobarbituric acid content in their blood was stated as a result of increase of plasma antioxidant protection activity in them. On the background of the low level of endotheliocytemia in healthy heifers on rearing there was revealed a considerable upward trend of the antiaggregational activity indices in the vascular wall with all tested inductors and their combinations.

For endotheliocytes of heifers on rearing a tendency for gradual increase of antithrombin III production, ensuring the necessary level of anticoagulant blood capacity is evident. In animals from 12 to 15 months of life this was accompanied with increase of plasminogen tissue activators secretion by the vascular wall.
