Резюме: Microorganisms, contet has been studed – bacteria and mould spores into drain raw materials - corn and wheat, which are traditional used in manufacturing of compounded feed and effect of heat conditioning during extrusion process. It has been determined better hygienic statum of extruded pet feed by number of microorganisems, during fixed parameters of extrusion process. Better effect was examed on nonsporeforming bacteria. Microflora in extruded feed is presented in the folloing strains: Penicillium, Cladosporium and Mucor. The effect of extrusion process was considerably on spores of moulds of strains Fusarium, Rhizopus and Aspergillus and strains of Cladosporium and Mucor remain more firmness. In selected manufacturing procces in these stadies (temperature, injected steam, main motor of extruder and effect into extruder barrel) was manufactured products, which quality properties was of high-grade (PDI and hardness).
