The productivity of young pigs grown for meat and slaughter quality of their products was estimated at use of feed with different levels and sources of selenium. Pigs of large white breed were used for scientific experiment that was carried out by method of groups (pairs-analogues). The level of inorganic and organic selenium in the diets of experimental groups was regulated by the introduction of feed of sodium selenite and Sel-Plex. Part of selenium in mixed fodder of poultry control group was 0.07 mg/kg of dry matter and in the fodder of pigs of 2-th, 3-th, 4-th and 5-th research groups that were 0.2; 0.2; 0.3 and 0.4 mg/kg of dry matter respectively. The animals of second group were administered in feed sodium selenite and 3, 4 and 5th – Sel-Plex. The feeding was done by group and feed was distributed twice – in morning and evening. It was proved introducing selenium in feed young pigs was improved the quality and biological value of meat. The inclusion of organic selenium at 0.3–0.4 mg/kg dry matter was contributed to increasing concentrations of selenium in meat by 36.8 and 48.0 %, copper – by 25.6 and 26.8, zinc – 20.8 and 21.3 % and was reduced the concentration of cadmium in 29.7–35.1 % mercury – in 18.8–19.2 % in meat. It was determined to trend to increasing of lead content in products slaughter of animals experimental groups. The use of sodium selenite compared to the organic compound is less positive impact on meat quality of pigs.
