Embodiment 1
[0019] A method for producing micro-ecological fermented feed using corn deep-processing by-products as raw materials includes the following steps: (1) selecting three kinds of probiotics, Bacillus subtilis, Aspergillus oryzae and Rhizopus, and cultivating them on inclined planes and shake flasks to obtain two kinds of probiotics. Grade seeds and mix them in a ratio of 1:1:1.5. The inoculation amount of each level was 1%, the culture temperature was 32°C, the culture time was 40 hours, and the pH value of the culture medium was 5.5; The secondary seeds obtained from the primary and secondary cultures on slant planes and shake flasks were compounded according to the ratio of 1:1:1. The inoculation amount of each level is 5%, the culture temperature is 30°C, the culture time is 30 hours, and the pH value of the culture medium is 7; (3) Preparation of fermentation medium: various by-products such as corn bran that appear in the deep processing of corn , germ cake, corn steep liq...
