A complex of medical and biological studies of the effect of 4-(hydroxyethyl)phenol ( p -tyrosol, aurol) on all life stages for the groups of different animals is considered. A substantial decrease in the level of mortality was revealed for each experimental group and at each life stage. The efficient action of aurol at the early life stages and during subsequent development of organisms was demonstrated. Aurol exhibits antioxidant properties, affects vascularization and neoangiogenesis and thus restores the nitroxidergic system of the brain, improves blood composition, strengthens the structures of the most essential systems of the organism, and decreases bird mortality at the early stage of life. The use of aurol in poultry breeding leads to early ovicell maturation in hen organisms, which causes an increase in egg-laying ability. In the cases of vaccination or diseases of birds, an increase in bird survival rate (90 %) is observed in the case of the treatment with known antibiotics in combination with aurol, compared to the reference group without aurol treatment (80 %). Neuroprotective action of aurol is exhibited as a sharp decrease in miscarriage rate during shearing pregnant goats. A positive effect of aurol application in cattle breeding causes the growth of more vigorous young individuals advancing in live weight by 5-7 % in comparison with the reference group. The long-term result of aurol action manifests itself in the animals of the experimental group during 25-30 days after injections and is explained by an increase in hemoglobin concentration and the high biological activity of blood serum. A substantial economic effect achieved during industrial tests of the maintenance of animals with the help of aurol at all stages of their life is the first example of an increase in productive longevity.
