The aim of the work was to develop methods of correction to be aimed at improving mineral adequate supply of quails’ organism by using feed additive "BeloAktiv." The relevance of this work is determined by lack of systematic research that would comprehensively characterized the patterns of metabolic processes, including mineral metabolism in the body of quail in terms of age and under actions nutrient supplements. As a result of experiments it is established that the feed additive in poultry diets affect the level of minerals in organs and tissues quail. It is established that the use of additives in fodder of experimental group of quails which are 42-days old increases the content increases a content of cooper in the thigh muscle to 15.02% in the bones - by 14.18% in feathers - by 5.9%, and in skin – 11.52% compared with the control group. Experiments which were conducted provide grounds for recommendations on the use of additive "BeloAktiv" in the amount of 0,15% of the basic diet of quail during the 17- to 72-day age to correct mineral metabolism of quails, to increase their productivity and improve product quality.
