The data about content of polyamines in broiler chickens blood and some tissues (liver, spleen, kidneys and thoracic muscle) at pre-slaughter stress are presented in the article. The spleen extract (70°alcohol solution in volume 1.4 ml per chicken) was added to the diet of broiler chickens of experimental groups by aerosol method. This extract was obtained with and without ultrasound application. 70°alcohol solution in the same volume and the same method was added to the diet of broiler chickens of control group five days beforeslaughter. The content of polyamines such as putrescin, spermine and spermidin in broiler chickens blood and some tissues was determined. The total amount of polyamines and concentration of putrescin, spermine and spermidin in broiler chickens blood and some tissues (except kidneys) was reliable higher compared to control after additional supplementary of the spleen extract to the diet of broiler chickens of experimental groups by aerosol method.
The putrescin, spermine and spermidin level was reliable lowest in blood and some tissues of broiler chickens of control group. The polyamines content in broiler chickens blood, liver and thoracic muscle was reliable highest in broiler chickens of the first experimental group after addition to the diet of the spleen extract with ultrasound application.
The investigations of the influence of polyamines such as putrescin, spermine and spermidin which was obtained from spleen with ultrasound application on farm animals and poultry immune status for organism resistance increasing and correction of negative impact of pre-slaughter stress will be prospects.
