Abstract: For normal growth and development of calves it is necessary to pay special attention to their feeding and balanced diets on essential amino acid. Amino acids needed by the body not only as a structural material, especially great is their role in the biosynthesis of numerous physiologically active compounds and structural compounds: nucleic acids, purine and pyrimidine bases, hormones, creatine, carnitine, vitamins and many others. Amino acids also perform the role of transport systems in the body and determine the activity of many enzymes. Thus, the search and synthesis of new sources of high quality protein feed with an optimal set of essential amino acids, mineral components and biologically active substances is an actual problem of modern science. The purpose of this study was to investigate the possibility of protefit usage in young cattle diets a new-feed additive, created from high quality food maize to identify the optimal nutritional intervention dose of protefit to determine its productive effect on body of animals in order to propose this supplement as a substitute for protein ingredients of the diet. Protefit nutritional interventionin the diets of calves instead of soy, pea and sunflower meal caused an optimization of an interstitial exchange which was accompanied by a high safety of livestock and a large increase in body weight. Protefit can be added into the diets of calves (20%) completely replacing other protein ingredients: soybean, pea, sunflower protein meal.
