Abstract: Our research is devoted to the study of problems and ways of producing ecologically safe broiler meat under conditions of technogenic agroecosphere. The work was carried out on the basis of a typical Ural farm (Chelyabinsk region, Russia); the work was consisted of two stages. The content of chemical elements in soil, water and feed samples was determined at the first stage; a method of reducing toxic elements in poultry meat was tested at the second stage. The broiler chickens of the “Smena 2” crossbreed was formed in 4 groups. The 1st group was the control group; the 2nd, 3rd and 4th (the experimental groups) received the basic ration of a biologically active complex of lucerne extract at a dose of 15, 30 and 60 mg per one kg of body weight, respectively, beginning from the 5th day of age. There was a redistribution of biogenic and toxic elements in the broiler liver; the number of biogenic elements of copper, zinc, cobalt, manganese increased by an average of 1.42; 1.5; 3.43 and 1.92times, respectively; the level of nickel and lead decreased by an average of 2.37 and 2.45 times, respectively. As a result of the application of the biologically active complex of plant origin, it was noted that with an increase in its dose, the content of toxic elements (lead and nickel) in broiler meat decreased by 1.19‒1.46 and 1.89‒1.92 times, respectively, in comparison with the control group. The research results determine the possibility of testing a biologically active complex of plant origin to reduce the level of toxic elements in the composition of products obtained from other farm animals.
