The article is devoted to the problem of improving the adaptive capacity of young highly productive animals using biologically active substances under intensive technologies during one of the critical periods of their development — weaning from sows. For this purpose, the effect of formic acid and dietary feed supplement “Humilid” on the free radical processes and antioxidant defense system of the piglet’s organism during the first 40 days from the birth was studied.

It was found that the addition of formic acid (2nd experimental group) and its complex with humic supplement (1st experimental group) to the standard ration for a month from 10- to 40-day age (18 days before and 12 days after weaning from sows) is accompanied by reducing the concentration of oxidative stress products. A reduction of the content of TBA-active products, lipid hydroperoxides and carbonyl groups of proteins in the animals of the experimental group was observed. It was established an increase of the parameters of antioxidant defense system in the piglet’s organism — the activity of superoxide dismutase and catalase in erythrocytes of the animals of the first experimental group under the administration of the complex additives. Therefore, combined action of organic acid and humic supplement most effectively manifested their antioxidant effect in the blood of piglets during critical periods of their life — 20 days of life and 2 days after weaning from sows (30 days of life).

It was concluded that it is recommended to add the complex of bioactive feed supplement “Humilid” and formic acid to the standard diet of piglets to activate their adaptive capacity and reduce stress factors in animals in the critical periods of their ontogenesis.
