Appraisement of new mixed fodder formulas for the fattening performance test was realized in the conditions of the Republic of Belarus by the example prevailing in the country Large White breed. Barley (Hordeum vulgare) proved to be one of the main components in swine feeding in Belarus. Forage wheat in mixed fodders for the fattening performance served a basic energy source and contained less dietary fibre than barley, as well as less concentration of antinutrients which interfere with digestion of rations than others crops (rye, triticale). Soybean and sunflower oil meal were included into analysed mixed fodders as the protein sources. Application of new mixed fodder formulas for fattening control realization according to the technical specifications of the Republic of Belarus 600039106.044 - 2007 was realized by the example of gilts of pigs of Large White breed. Research results showed that new studied formulas made it possible to obtain the higher intensity of swine development indices (on 52-72 grams) in comparison with the traditional formulas of mixed fodders (technical specifications of the Republic of Belarus 06093149.065-2000). New mixed fodder recipes did not render harmful effect on health and safety of livestock. At the same time, the analysed recipes of mixed fodders did not authentically influence the carcass indicators (carcass length, fat thickness, loin eye area, ham weight, slaughter yield)
