The Far Eastern region is experiencing an acute shortage of micro and macroelements in the soil, which leads to the inferiority of the fodder base in the livestock industry. Local compound feeds do not meet the average Russian standards for nutrition and digestibility, which often leads to large economic losses, diseases, as well as the death of the animal. Poultry farming is one of the most highly efficient branches of animal husbandry. In the process of growing chickens should receive feed enriched with minerals and trace elements – this is required for the further development of poultry. In this regard, it is worth paying special attention to the preparation of a proper diet using biologically active additives. The purpose of our study is to analyze the effect of iodine, cobalt and selenium in mineral and organic form in combination with the enzymatic probiotic "Vitacell" on the growth and development indicators of young laying hens of an industrial herd in the Amur region conditions. The scientific work carried out a detailed study of the chemical composition of the fodder base, as well as the positive effect of the probiotic "Vitacell" on the growth and development of young chickens. A comparison was made between the control group, which received standard compound feed, and three experimental groups, which received compound feed with the addition of asparaginates iodine, cobalt, selenium and probiotic "Vitacell". As a result of the study, the main directions of feed optimization are proposed, taking into account the administration of asparaginates iodine, cobalt, selenium and the enzymatic probiotic "Vitacell" into standard compound feed. Their positive influence on the growth and development of poultry has been proven. A production check of the research results showed the economic feasibility of the combined use of asparaginates iodine, cobalt, selenium and the enzymatic probiotic "Vitacell".
