The ecological conditions of fodder production and agricultural technology for the cultivation of fodder resources have a great influence on the characteristics in the chemical composition and nutritional value of local fodders, determines their yield and the economic aspect of production. The Amur Region belongs to a biogeochemical region with a sharp deficiency in the biosphere of a number of normalized macro-and microelements vital for animals. In this regard, mineral supplements and premixes for animals and poultry imported from other regions can be not only useless, but even harmful. In order to determine the need for feeding with minerals, you need to know which chemical elements are contained in feed and in the diet in insufficient quantities, and which in excess. Along with this, the normalized microelements introduced into the composition of feed and rations in the form of mineral salts are poorly digested by all types of animals. It is most effective to feed them in combination with organic nutrients. In this regard, the purpose of the experimental research was to study the possibility of using feed additives made from local non-traditional feed resources in feeding cattle. As a result of scientific, economic and physiological (balance) experiments, the effectiveness of using feed additives made from local fodder resources in feeding cattle for growth, metabolism and milk productivity was determined.
