The data about content some nonspecific body resistance indices and certainhormonesin bull blood after using of animal natural origin immunomodulators at pre-slaughter stress are presented in the article.

Spleen extract biologically active substances polyamines were as the immunomodulators and antistressors at pre-slaughter stress. The spleen extract (70°alcohol solution in volume 0.7 ml/кг) were added to the diet of bulls of experimental group by aerosol method. The 70°alcohol solution in the same volume and the same method were added to the diet of control group bulls five days before slaughter.Adrenocortico tropichormone, cortisoland aldosterone level in blood of bulls which received food with spleen extract (experimental group) werereliable lower after transportation compared to control group bulls that caused decreasing pre-slaughter stress.

Phagocyticactivityof blood neutrophils were increasedintheexperimentalgroupbullsbloodcomparedwithcontrolsboth, before— by 7 % (P<0.01) as well as aftertransportationbefore slaughterby 9 % (P<0.05), respectively were established. Spleen extract polyamines as the immunomodulators and antistressors most effectively influenced on certain hormones content and some nonspecific body resistance indices in bulls bloodafter transportation before slaughter.

The results which obtained can to be used in researches of certain cellimmunity, nonspecific resistanceindicesandconcentrationof stress hormones, such as cortisol, on farm animals and poultry for organism resistance increasing, correction and avoid their pre-slaughter stress and improveproduct quality.
