The invention belongs to the field of biological feed, and relates to a high-efficiency and low-cost
fermentation feed processing method based on bean dregs and application; the
processing method comprises the steps of activating a strain to obtain
fermentation seed liquid of bacillus,
yeast and
lactic acid bacteria; mixing the bean dregs with
bran or rice
bran, then adding
sucrose, adding
cellulase, cellobiase, glucoamylase,
xylanase, mannanase and beta-
glucanase, mixing to obtain a primary aerobic
fermentation medium, inoculating the bacillus fermentation seed liquid and the
yeast fermentation seed liquid for primary aerobic fermentation, obtaining a primary fermentation mixture after fermentation, and then inoculating the
lactic acid bacteria fermentation seed liquid for anaerobic fermentation under sealed conditions to obtain a finished product; an
bacteria-
enzyme cooperative fermentation and aerobic and anaerobic step-by-step fermentation mode is adopted, the fermentation is completed, the conversion degree of soybean
peptide is high, the removal rate of
trypsin inhibitor is 85% or above, each
mycotoxin is lower than the feed
hygiene limit standard of China; the feed is good in
palatability, and favored by animals, and the economic efficiency is high.
