The article considers modern directions of expansion of the raw material base in the production of mixed fodder for egg chickens. One of the most important conditions for the modern production of high quality fodder, protein concentrates and premixes is the search and use of new raw materials of plant and animal origin. At the same time, the share of grain in these products is not more than 50%, and in the recipes of the feed industry of the leading countries 20-30%. Modern technologies provide the use of any feed, as an important raw material for the feed industry, derived from waste and by-products of food industries, which are characterized by high fodder quality at a low cost. Domestic producers of feed are now forced to solve the problem of optimizing the use of cereals, in particular, to reduce the content of cereals in the formulation of feed and the content of fillers in the formulation of premixes. The problem of expanding the assortment of feed resources in the production of mixed fodder, premixes, and the use of cheaper fodder raw materials to reduce the cost of finished products is acute. For the cost-effective growth of egg chickens, high-quality feed is required, selected for each species, taking into account the age and physiological state of the bird [1]. In recent years, the production of eggs in Ukraine remained at 19 billion units. a year, but starting from 2015, we see a significant decline. A similar decline in production is associated with a decrease in the number of egg chickens. If we consider the production of eggs in terms of the categories of enterprises, it can be noted that in the households the volume of production in recent years is also decreasing, but overall, the rate of decline in production is much slower and smaller than that of agricultural enterprises [2]. In order to expand the raw material base of feed production and provide the necessary level of productivity of egg chickens, the introduction of corn-phosphate feed (KKFK) concentrate in feed was proposed. The features of the compounding formulations were studied on the control and experimental recipes. The formulation of mixed fodders with the use of KKFK for balanced diet of chickens has been developed, an increase in the level of exchange energy, nutritional value of feed and its profitability has been established.
