A technology of application autolysis of fodder yeasts (AFY) for the production of products with higher protein content, digestible aminoacids and other nutritive and biologically active substances in comparison with the standard fodder yeasts (provit) was tested in the conditions of the Republic of Belarus by an example of three groups of swine. Animals of the first (control) group were fed with combined feed SK-26 with addition of 2% of provit. Animals of the second group were fed with combined feed SR-26with addition of 2% of AFY, the third group - with addition 4% of AFY. Provit and AFY were included into combined feed instead of excluded protein components in equivalent number. Research results showed that autolysis of fodder yeasts did not render negative influence on productivity of fattening stores. Average daily weight gain of stores was 637-674 g. Calculation of economic efficiency of combined feeding application of 2 and 4% of AFY showed that application of 2% AFY was more economically profitable
