The mechanisms of support of the prooxidant-antioxidant balance in the liver tissues of geese in hypo- and hyperoxia during the transition from embryonic to postnatal development. It is proved that the formation of adaptive response to these conditions by running the neuro-humoral mechanisms that are, first, to stimulate the synthesis of antioxidants of protein nature, and secondly, to reduce the unsaturation of fatty acids in the lipids of the liver, which greatly increases their resistance to the active forms of oxygenation and thirdly, to increase the efficiency of the antioxidant defense system by improving the consistency of its components performance.

Keywords: hypo- and hyperoxia, lipids peroxidation, prooxidant-antioxidant balance, reactive oxygenation, the level of consistency, unsaturated fatty acids
