ABSTRACT.
As part of an ongoing study to assess the effect of cakes (hemp, flax and sunflower) in concentrations of 5% and 10% of the total diet. We conducted a comprehensive analysis of the potential for their use in feeding
broiler chickens. One of the stages of the project was to determine the level of absorption and accumulation of microelements in tissues depending on the diet. In this work, an analysis of the assimilation and accumulation of toxic elements from the group of heavy metals (Al, Cd, Pb) was carried out. The results of the study indicate a significant decrease in the studied elements in biological samples of most of the studied groups. However, a pronounced dosedependent effect between the dose and type of cake and a systemic reduction in all analyzed xenobiotics was not established in the study.
