Nonspecific resistance and some hormones content in bulls blood under pre-slaughter stress correction
Journal Title: Біологія тварин - Year 2015, Vol 17, Issue 2
Abstract
The data about content some nonspecific body resistance indices and certain hormones in 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. Adrenocorticotropic hormone, cortisol and aldosterone level in blood of bulls which received food with spleen extract (experimental group) were reliable lower after transportation compared to control group bulls that caused decreasing pre-slaughter stress. Phagocytic activity of blood neutrophils were increased in the experimental group bulls blood compared with controls both, before — by 7 % (P<0.01) as well as after transportation before slaughter — by 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 blood after transportation before slaughter. The results which obtained can to be used in researches of certain cell immunity, nonspecific resistance indices and concentration of stress hormones, such as cortisol, on farm animals and poultry for organism resistance increasing, correction and avoid their pre-slaughter stress and improve product quality.
