Abstract

The article is devoted to problem improving adaptive capacity of young highly productive animals under intensive technologies during one of the critical periods of their development through biologically active substances. 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 a complex supplement 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 and activation of glutathione chain of antioxidant defense system in animals blood. 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 also revealed the increase of activities of glutathioneperoxidase, glutathionereductase and glutathione content in these piglets compared with control. Therefore, combined action of organic acid and Humic supplement positively affected on the antioxidant activity in the blood of animals in the most critical period – 20 days old from the birth and 2 days after weaning from sows (30 days old from the birth). It was concluded that the complex of bioactive feed supplement Humilid and formic acid can add to the standard diet of piglets to activate their adaptive capacity and reduce stress factors in animals in one of the most critical periods of their ontogenesis.
