A strategy for application of adaptogenеs as stimulators of productivity in agricultural animals

In postnatal ontogenesis, there are definite physiological periods, when certain functional systems are changing significantly, and a susceptibility of animals not only to the negative factors, but also to stimulating agents becomes extremely high, so the use of stimulators leads to the more prolonged positive results with high economic efficiency. An application of such stimulating agents is proven to promote the realization of genetic potential of animal productivity. Of the known dietary supplements, a tincture of Eleutherococcus senticosus Maxsim with adaptogenic activity is the most effective. To rise a viability of young and adult individuals, as well as productive and reproductive traits in cattle and small ruminants, pigs, poultry (chickens, ducks, quail), deer, and also in the fur farming, a short-term feeding with Eleutherococcus senticosus tincture or powdered roots should be used at definite «critical» periods in ontogenesis.
