The invention relates to an extraction method for ganoderma lucidum components, a biological feed and a preparation method thereof, and belongs to the field of natural product processing. The extraction method comprises the following steps: crushing ganoderma lucidum fruiting bodies, and performing reflux extraction on fat-soluble components to obtain ganoderma lucidum fats and a first residue; performing enzymolysis on the first residue by virtue of cellulase, hemicellulase and papain, adding an ethanol-water solution, performing refluxing treatment to obtain reflux and a second residue, eluting the reflux by virtue of a D101 macroporous adsorption resin chromatographic column, and collecting eluted liquid to obtain ganoderma lucidum triterpene; performing ultrasonic extraction on the second residue to obtain extract and a third residue, and purifying the extract to obtain ganoderma lucidum polysaccharides by virtue of DEAE-cellulose. The preparation method comprises the following steps: mixing the third res
