The review considers the problems of mycotoxin content reduction in feed using physical methods and application of these methods when producing compound feeds. The analysis of scientific publications on the topic under research has shown that physical methods of lowering mycotoxin content in feed are rather effective. These methods include cleaning and sorting of raw materials, grain husking, grain refining with removal of outer layers of grain, heating, extrusion, the effect of non-ionizing and ionizing radiation and cold plasma. Thermal methods (heating and extrusion) and ionizing radiation (gamma-radiation and electron beam) are most effective for a mycotoxin content reduction in feed. The new method of feed detoxication by cold plasma is perspective, but requires additional research. To make the removal of mycotoxins fully complete it is more efficient to combine different physical methods, namely cleaning and sorting at the preliminary stage and heating or irradiation at the final stage. But before applying physical methods into the compound feed industry the rational parameters of their execution should be determined and optimum combinations of different methods for certain mycotoxins should be specified. The subject area of mycotoxin content reduction in feed using physical methods is perspective, but requires carrying out additional research.
