In conditions of market relations for the agricultural enterprises the defining factor of the cost price of cattle-breeding production are forages with which cost prices in structure amount to more than 70%. Low efficiency of feeding animals increases the period of breeding and feeding and, as consequence, increases industrial expenses for power resources, the salary and amortization. As a result cattle-breeding production made in many farms becomes unprofitable and noncompetitive. In this connection RUE "Scientific and Practical Centre of the National Academy of Sciences of Belarus for Agriculture Mechanization" works on creation and introduction in manufacture feed mill and installations, of productivity from 1,5 up to 5 ton/hour with weight-measuring system of components batching and their periodic mixing are conducted. Application of new technologies and resource-saving the equipment for manufacture of mixed fodders and fodder additives directly in facilities, using secondary resources and local sources of raw material, will allow to cut down transport expenses on transportation of initial raw material and a ready product and to save only on transportations annually 25-30 thousand tons of fuel, to provide animals with the fresh good-quality mixed fodder of a demanded composition. Economic benefit as a whole on republic will make 18-20 million US dollars.

Wastes of animal industries are valuable high-protein forage for animals and birds. However the technology of waste processing should guarantee safe toxicological and microbiological status of a ready product, its high fodder value, an opportunity of long storage and ecological safety. As a basis of new technology on processing waste of animal industries is extrusion of the material. Sharp pressure difference at an output extruded article from a trunk extrusion machine, leads to break cell wall, including cell wall of microorganisms, fungi and mustiness. During "dry" extrusion of animal industries waste exposed in short-term (up to 30 seconds) to influence of a heat (up to 175°?), at pressure up to 40 atm., and also to friction in the damp environment. Short-term temperature processing renders the minimal influence on quality of fiber, destroying in him only secondary communications, not destroying amino acids (assimilation a protein makes 90%, lysine comprehensibility up to 88%), inactivation antinutritious factors, destroys or suppresses up to a comprehensible level toxins of bacteria, fungi and mustiness. For 30 seconds of stay of raw material in extrusion machine moisture content goes down to 50% (from initial), the heat and pressure will neutralize action of the enzymes contained in the waste that promotes substantial growth of periods of storage of finished goods.
