Introduction. In the conditions of technogenesis, the problem of providing the population with environmentally safe poultry products has become very urgent. The problem of the transfer of heavy metals along the trophic chain, in the case of contamination of compound feed and feed raw materials with toxic elements generated as a result of industrial emissions and their increased natural content in soils, is in the center of attention of specialists. Purpose ‒ to study the content of microelements and heavy metals in meat and liver of broiler chickens when including highly dispersed shungite and zeolite in feeding diets. Materials and methods. For the purpose of the experiment, 40 broiler chickens were used, grouped with 5 heads in each group. The content of cadmium, lead, iron, zinc and copper was determined using generally accepted methods. Results, discussion. The obtained results show that the use of zeolite and shungite contributes to significant sorption of cadmium and lead. Thus, this leads to a decrease in the accumulation of toxic elements in the liver of broiler chickens to a level safe for nutrition ‒ 0.03 mg/kg for cadmium and 0.2 mg/kg for lead. Conclusion. The combined use of the studied minerals in a dose of 0.5 % in the diets of broiler chickens, separately or in combination, when feed is contaminated with cadmium and lead in concentrations up to 0.5 MDU leads to a decrease in the accumulation of toxic elements in organs.
