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.
