The article deals with investigation of adaptive capacity increasing of the organism of highly productive animals during the most critical periods of their development - gestating, lactation and neonatal period. The state of antioxidant defense system in the blood of lactating sows and their piglets in the period from birth to 21 days old under the actions of ascorbic acid were analyzed. It was established that the addition ascorbic acid to the diet of sows during the 10 days before farrowing causes an increase of antioxidant defense system of the organism as sows and their piglets. In the blood of animals of research group the increase of activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glutathione levels were observed in sows compared with pigs kept on a standard diet. It was concluded that ascorbic acid can increase adaptive capacity of the sows after farrowing and positively effected on the resistance of newborn piglets, stimulates anti-stress properties and has a prolonged effect.
