The article describes the main positive qualities of soybean meal and the benefits of using it in poultry feed. Soybean meal is considered to be an ideal protein component of vegetable origin. The physicochemical, consumer value and safety indicators of soybean meal according to DSTU 4593:2006 (soybean meal) are presented. The expediency of replacing soybean meal in poultry feed due to its high cost for cheaper protein components is substantiated. Fodder yeast and sunflower meal are the main protein components of vegetable origin that are close to soybean meal in chemical composition. In order to reduce the cost of compound feed, we have proposed the optimal composition of protein feed additive (PFA) for replacement soybean meal in feed recipes. With the help of the software complex "Korm Optima Expert" the recipe of PFA of different composition was calculated. We have selected the following components for the development of recipes: sunflower meal, yeast fodder, wheat flour meal, wheat bran, sunflower oil, lysine monochloride, L-threonine, L-tryptophan, limestone flour. The maximum possible norm of PFA input into the compound feeds was determined by optimization. At the same time, the limitation of input of soybean meal and all PFA components into the poultry feeds were taken into account. The limitation of input of PFA components into the poultry feeds recipes differ at different stages of growth and development of poultry. In view of this, the maximum possible norm of PFA input into the compound feeds ranges from 8 to 18 %, depending on the age and destination of the poultry. [ABSTRACT FROM AUTHOR]
