INFLUENCE OF DIFFERENT LEVELS AND SOURCES OF SELENIUM IN PIGLET MIXED FODDER ON PRODUCTIVITY AND HEAVY METALS CONTENT IN THE SLAUGHTER PRODUCTS

Scientific papers analysis proves the feasibility of using selen containing preparates in animals diets to reduce mercury, cadmium and lead transformation in products. This allows to increase productivity and quality of livestock slaughter products.

Different levels (0.2, 0.3, 0.4 mg / kg dry matter) and sources of selenium (sodium selenite, Sel-Plex) adding into complete feed showed that an organic compound of selenium is the most effective for young pigs. Its additional introduction to the feed to achieve the total content of selenium at 0.3–0.4 mg / kg of dry matter helped to reduce the concentration of cadmium in 29.7–35.1 % and mercury – by 18.8–19.2 % in the flesh. The trend to reduce lead content in research groups animals slaughter products is revealed. The use of sodium selenite compared to the organic compound has less positive impact on pigs performance and meat quality.

Key words: selenium, pigs, performance, cadmium, lead, mercury.
