Possibility of increasing of natural resistance of young livestock animals and productivity of piglets after application of experimental feed additive including dolomite powder was realized in the conditions of the Republic of Belarus. In course of study there were analyzed housing conditions of piglets; the hygienic examination of feeding rations; influence of dolomitic meal on piglet resistance and productivity. Piglets of the first (control) group were fed with standard total ration. Animals of the second and the third experimental groups were given dolomite powder in ratio of 1% and 2% of combined feed mass. Chemical content of dolomite powder, hematological indexes, disease incidence and piglet productivity were analyzed. The research results showed that in feeding rations of piglets in the analyzed swine breeding complex there was stated the deficit of calcium (14%), phosphorous (26%), magnesium (15%), cuprum (9%), zinc (27%) and manganese (27%). Research results showed that application of dolomite meal is efficient for the prophylaxis of mineral deficiency, and made it possible to increase the level natural resistance: serum bactericidal activity - on 16,4% and hemoglobin - on 19%. The optimal dolomite dose of dolomite was 2% and it promoted the lowering of disease incidence, increasing of viability and average daily weight gain
