AGE-RELATED PECULIARITIES OF ANTIOXIDANT SYSTEM FUNCTIONING IN THE BLOOD OF OSTRICHES
Bila Tserkva National Agrarian University, Ukraine;
The intensity of lipid peroxidation, activity of some enzymes antioxidant system – superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-S-transferase, amount of recovered glutathione and ceruloplasmin in the blood serum of ostriches in a period from 6- to 60-month age were first investigated. The increase of concentration of lipid peroxidation products is accompanied by the decline of amount of general lipids in the ostriches blood. Every life cycle period of ostriches is characterized by the indexes of functioning of the antioxidant system and intensity of accumulation intermediate lipid peroxidation products inherent in it. The pubescence period and intensive oviposition are characterized by the increase of products lipid peroxidation concentration and decrease of antioxidant enzymes activity, which can testify to the exhaustion of protective possibilities of enzymatic link of antioxidant defence.
Key words: ostrich (Struthio cаmelus), blood, lipid peroxidation, enzymes of the antioxidant system.
