[The factors of antioxidant defence in the blood and liver of pheasants during ontogenesis].
The changes in activity of antioxidant enzymes of LPO products and lipophilic bioantioxidants of pheasants during the period from 1 day up to 60-day age was investigated for the first time. It is shown, that insufficiently generated enzymatic antioxidant systems is a cause and result of high intensity of processes of free-radical LPO in 1-day pheasants tissues. The compensated increase of antioxidant enzymes (SOD, CAT) activity during the early period of postnatal ontogenesis does not prevent from the fast exhaustion of a pool of the main lipophilic bioantioxidants that in its turn provokes the inhibition of antioxidant system enzymes reactions. This results in the decrease of adaptability of wild birds in conditions of artificial breeding.
