In conditions of intensification of growth and improvement of farm animals and birds, in order to maintain the immune status of the organism it is necessary to monitor the state of the body's antioxidant system. The concentration of free radicals in the cells of the body can reach levels, at which the own antioxidant system is not able to deactivate the damaging agents, as a result of which oxidative stress can occur. Different remedies are used to correct oxidative stress, including natural and synthetic of various chemical nature, possessing antioxidant activity (AOA). The biochemical structure of vegetable origin remedies is close to the structure of metabolites of living organisms, which is conditioned by adaptation through evolution and correspondingly these remedies are more easily submit to the influence of fermentative systems, compared to synthetic analogues. In this way, the problem of researching and studying new opportunities and phytoprotective sources of natural antioxidants is currently being pursued. In this paper will be elucidated results about the influence of polyphenols extracted from nettle on the antioxidant activity in the blood serum of roosters.
