FIELD: chemistry.
SUBSTANCE: invention relates to wood-chemical industry and can be used for processing of aspen bark with production of biologically active fodder additives for cattle breeding. Method for processing aspen bark provides extraction of milled aspen bark with glycerine at hydro modulus of 1:3 at temperature of 60–110 °C for 2–5 hours, wherein glycerine after extraction is not distilled, and is used in the obtained product as a preserving agent.
EFFECT: proposed method for processing aspen bark allows to produce biologically active product replenishing vitamins deficiency in animals.
