The aim of this work was to analyze the available data concerning the characteristics and effects of micro elements and their chelate forms in swine and poultry nutrition on production parameters and cholesterol content in the tissues of broiler chickens. Usage of copper chelate forms in piglets nutrition led to increased feed consumption by 4% and daily gain weight of 4.2%. The same trend was observed in fattening pigs fed diets supplemented with 200 ppm of copper, with increased daily gain by 14.3%. The research, which aimed was to explore the possibility of significantly lower inclusion levels of minerals, the introduction of organically bound forms in broilers have not any significant differences, indicating that the much lower levels of minerals in organic form had positive impact on production parameters of broiler chickens, and improved production results of hens and parents of heavy line hybrids. The inclusion of molybdenum and sulfur in feed with high levels of copper, 100 and 200 ppm had a positive effect on the broilers growth intensity. Adding 50 ppm of molybdenum and 50 ppm of sulfur in the mixture with 100 ppm of copper, at the end of the experimental period, increased the body weight of chickens for 8.35% compared to the control group, while in the second fattening period, the group with addition of 100 ppm of copper was most effective. Also it is observed a significantly lower concentration of copper (P< 0.01) in the liver in the presence of molybdenum, with and without the presence of sulfur, compared to groups that contained only copper in feed. The use of chelate forms of minerals in monogastric nutrition is a newer trend that is still not fully accepted in practical production and further research in this area is needed. In deciding whether to use a more efficient, but also more expensive mineral chelate forms, environmental requirements must be taken into account.
