FIELD: technology of processing of raw materials of natural origin, particularly, antlers of Siberian stags, Manchurian deers, dapple and northern deers for producing biologically active powder from antlers applicable in food, medical and biotechnological industries. SUBSTANCE: method includes mechanical removal of hair side from antlers of Siberian stag, Manchurian or dapple deers, crushing of material to obtain particles sizing 5-10 mm and its drying with air flow at temperature of not in excess of 70 C, repeated crushing of material to average size of particles of 0.1 mm and replaced drying in air flow at the same temperature. Introduced into obtained product is ferromagnetic powder with particles sizing 1.0-50.0 mcm in ratio from 1:1 to 2:1. Product is subjected to additional reduction in size in vortex mill in presence of the ferromagnetic powder to obtain ultradispersed material from antlers with particles sizing 0.1-30 mcm and moisture content of not in excess of 2 wt.%. Ferromagnetic powder is removed from mixture by means of permanent magnetic field. Ready powdery product is packed in vacuum packages. EFFECT: preparation of biologically active powder product from antlers featuring high bioaccessibility and assimilation by organism. 3 cl, 1 tbl, 5 ex
