The invention relates to the field of
fermentation engineering and feed
raw material and particularly discloses disc
solid aerobic
fermentation soybean meal as well as a preparation method and application thereof. The preparation method comprises the following steps:
raw material moistening with water, cooking, cooling, inoculating, carrying out disc
fermentation, carrying out low-temperature
drying, crushing, weighing and packaging, wherein the
inoculation and fermentation comprises first-stage
aspergillus oryzae
solid-state culture and fermentation and second-stage
saccharomyces cerevisiae culture and fermentation; the disc is used as a fermentation container, so that intelligent regulation and mechanical
continuous production are realized; the obtained fermented
soybean meal is stable and reliable in quality, rich in digestive enzymes and
yeast metabolites, high in crude
protein and acid-soluble
protein content, low in anti-nutritional factor and good in
palatability and food calling effect, and the in-vitro bionic digestibility is larger than or equal to 80%, the antinutritional factor is low, and the
soybean meal has good
palatability and food calling effect; the fermented soybean
meal is used in
animal breeding and can significantly improve
digestion and absorption of animals to feed nutrients, improve growth performance, enhance
immunity, reduce a feed-weight ratio, improve unit capacity and bring
economic benefits to farmers.
