The application discloses a method for preparing green biological feed from
maranta arundinacea polyphenol flavonoid extraction residues, and belongs to the technical field of
agricultural waste resource utilization. The application takes
maranta arundinacea polyphenol flavonoid extraction residues as a main
raw material, and through pretreatment, composite strain anaerobic
fermentation and low-temperature
drying and crushing, high-
protein and low-
fiber green biological feed is prepared. The application realizes harmless and high-value utilization of agricultural wastes, and has the advantages of green, simple process, low cost, safe and high-quality feed, good
palatability, effective promotion of growth of
livestock and poultry, and enhancement of
immunity, and remarkable economic, ecological and
social benefits.
