For the first time, the composition of a feed additive from modern biologically active substances and natural components with a synergistic effect has been scientifically substantiated, which is capable of forming biologically complete, environmentally friendly products in animals at the final stage of growing (a month before slaughter). This additive consists of,%: 95.5 – micronized full fat soya (source of leucine – controller of adipopexis), 3.5 – betaine (osmoprotection moisture retention in muscle tissue), 0.3 – L-carnitine (an activator of energy metabolism), 0.7 – Lisofort (emulsifier of fats, improving its digestion). It was found that the use of a functional feed additive in the amount of 2.0% 30 days before slaughter of pigs increases its productivity by 9.3%, reduces feed costs for products by 8.4%. In muscle tissue, fat content increased by 0.85 %, characterizing the improvement of “marbling” of meat. The moisture-binding ability increased by 8.0%, the color intensity by 5.0 units of extinction, and a protein-quality indicator of meat due to an increase of 4.68% in the content of essential amino acids. The economic efficiency of the use of functional feed additives for the final fattening of pigs was calculated.
