The technologies of production of starting mixed feed don't consider the requirements of the poultry in homogeneous mixed feed with the high content of protein. The aim of the study was to increase the efficiency of production and use of mixed feed by extruding mixtures of the grinded grain and sub-standard eggs without shell. Analitical and mathematic-statistical methods have been used in the work. The technological way of enrichment of grain raw material by protein of an animal origin provides receiving of a preliminary mixture of the grinded grain of corn and sub-standard eggs without shell in the ratio 1:1, mixing of the preliminary mixture with the grinded corn which remained, and extruding received mixtures. The optimal quantity of eggs in the mixture is 10 %. The recipes of starting mixed feed have been developed on the basis of studying of requirements in nutritious and biologically active substances for chickens. The improved basic technological scheme of manufacture of starting mixed feed for the poultry provides possibility of manufacture of the extruded feed additive (EFA) on the equipment of the feed mill. The necessity of receiving of preliminary mixture of microcomponents and extruded feed additive by two-phases mixing of them in the ratio 1:1 at the first stage of mixing and 1:2 at the second stage has been established experimentally. It is necessary for uniform distribution of microcomponents in mixed feed taking into consideration weight of single consumption of a forage by the poultry.
