The results of determination of protein fractions content and cortisol concentrations in plasma of laboratory animals, which further added to the feed of natural origin biologically active substances: spleen, Echinacea and Schisándra chinénsis extracts, growing grain, are presented in the article. Aerosol introduction of spleen extract to the rats feed increases the β- and γ-globulin concentration and decreases of cortisol level in the rats blood plasma in comparison with the control, may indicate about reducing the stress of the animal before slaughter. The results which obtained in model experiment on rats can to use in researches of cell immunity indices and stress hormones, such as cortisol, on farm animals for organism resistance increasing, correction and avoid their pre-slaughter stress.


Keywords: rats, pre-slaughter stress, Echinacea and Schisándra chinénsis extracts, protein fractions, cortisol
