Embodiment 1
[0028] A method for producing high-efficiency broiler feed using fermented corn stalks:
[0029] Step 1, crush the corn stalks through 20 meshes, select 5% of the total amount of corn stalks and use ammonia water with a mass concentration of 14% for 2 days, add ammonia water with a mass concentration of 15% for 3 days, and then add 16% ammonia water The ammonia water was treated for 3 days, and it was used for standby;
[0030] Step 2. Under the conditions of 164.5°C temperature and 0.6MPa, use an orbital autoclave to treat the pulverized and ammonified corn stalks with hot and humid steam for 40 minutes, and then set aside;
[0031] Step 3. Separating and screening Aspergillus oryzae and Candida ruthenicum for the production of single-cell protein by fermentation of corn stalks, as well as Bacillus licheniformis and Pediococcus pentosaceae with strong enzyme-producing ability to make liquid strains by three-stage expansion;
[0032] Step 4. Preparation of nutrient solution: ...

[0036] A method for producing high-efficiency broiler feed using fermented corn stalks:
[0037] Step 1. Crush the corn stalks through 15 meshes, select 4% of the total amount of corn stalks and use ammonia water with a mass concentration of 14% for 2 days, add ammonia water with a mass concentration of 16% for 3 days, and then add 20% ammonia water The ammonia water was treated for 3 days, and it was used for standby;
[0038] Step 2. Under the conditions of 160° C. and 0.7 MPa, use an orbital autoclave to treat the pulverized and ammoniated corn stalks with hot and humid steam for 50 minutes, and then set aside;
[0039] Step 3. Separating and screening Aspergillus oryzae and Candida ruthenicum for the production of single-cell protein by fermentation of corn stalks, as well as Bacillus licheniformis and Pediococcus pentosaceae with strong enzyme-producing ability to make liquid strains by three-stage expansion;

Embodiment 3
[0044] A method for producing high-efficiency broiler feed using fermented corn stalks:
[0045] Step 1: crush the corn stalks through 30 meshes, select 6% of the total amount of corn stalks and treat them with ammonia water with a mass concentration of 16% for 3 days, add ammonia water with a mass concentration of 18% for 3 days, and then add 20% ammonia water The ammonia water was treated for 2 days, and it was used for standby;
[0046] Step 2. Under the conditions of 167°C temperature and 0.5MPa, use an orbital autoclave to treat the pulverized and ammonified corn stalks with hot and humid steam for 50 minutes, and then set aside;
[0047] Step 3. Separating and screening Aspergillus oryzae and Candida ruthenicum for the production of single-cell protein by fermentation of corn stalks, as well as Bacillus licheniformis and Pediococcus pentosaceae with strong enzyme-producing ability to make liquid strains by three-stage expansion;
[0048] Step 4. Preparation of nutrient ...
