The invention relates to a method for producing a high-
protein feed from waste distiller's grain of Baijiu, which includes the following steps: (1) material pretreatment: a beater is used for beatingfresh raw distiller's grain of Baijiu into uniform particles, and the
diameter of the particles is about 1.5mm to 3mm; (2) defibering treatment:
endospore-forming
bacteria are screened out and added with 98 to 98.5 percent of raw distiller's grain, 0.9 to 1 percent of
starch and 1 to 1.1 percent of soybean flour,
solid-state
fermentation is carried out,
cellulase activity is kept as high as 14.204U / mL, and thereby waste distiller's grain of Baijiu is obtained; (3)
fermentation: candida and
pichia pastoris are screened out, the proportion of candida to
pichia pastoris is 1:1, the
inoculation amount is 10 percent, and with 85 to 89 percent of waste distiller's grain of Baijiu, 9 to 11 percent of
bran, 1 to 2 percent of
ammonium sulfate and 1 to 2 percent of quick
lime,
solid-state
fermentation is carried out for 60 hours. By means of modern microbial technology, the method decomposes substances in the distiller's grain, such as residual
starch, crude
protein, crude fat and crude fibers,so that the distiller's grain has richer nutritional ingredients and can be better digested and absorbed by animals, consequently, not only is the problem of waste distiller's grain solved, but also value in use and economic benefit are created, and the comprehensive utilization of residual
starch of the distiller's grain is realized.
