Abstract: A method for producing an animal feed has the steps of: cultivating funguses including actinomycess, deotrichum candidum, cellulose mono-saturated bacteria, lactic ferments, phycolmycete, protist, tirchoderma, saccharomyces cerevisiae, candida utilis, and aspergillus niger; producing fermenter by cultivating funguses to be fermented and then drying the cultivated funguses, and then by mixing the cultivated and dried funguses with sodium chloride, catalyzer and calcium oxide; mixing the produced fermenter with a raw material for the animal feed, the raw material being a mixture of one or more of grain, stem of field crop, power of plants, feces of livestock, waste of industrial ferments; and putting the mixture of the raw material and the fermenter in a sealed container, the sealed container being formed of different types of plastic film in multiple layers, and has a check valve formed on one side.
