Problems solved by technology

[0003] When raising broilers, corn stalks are used as ingredients, and the amount used is not easy to be too much. Too much is not conducive to the growth of broilers, the growth rate of broilers is slow, and the feeding efficiency is low.

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: ...

Abstract

Provided is a method for producing high-efficiency broiler feed by utilization of corn straw fermentation. Only corn straws are employed, and the corn straws are subjected to treatments of crushing, ammonia water treatment, steaming, fermentation and the like. The utilization rate of corn straws is raised, the cost is lowered, the broiler feeding rate is raised and the slaughter quality is improved.

Description

technical field [0001] The invention relates to the field of methods for raising broilers, in particular to a method for producing high-efficiency broiler feed by using fermented corn stalks. technical background [0002] It is estimated that by 2015, we will need a feed protein gap of 38×10 4 As mentioned above, opening up new sources of raw materials and improving feed utilization is currently a worldwide research topic. The output of corn stalks in my country is huge, but due to the low digestible protein content and high crude fiber content of straw, most of the cellulose cannot be used by livestock and poultry. It is digested and decomposed by the gastrointestinal tract, so the nutritional value is low, and most of them are directly returned to the field or burned, which is an astonishing waste of resources and causes environmental pollution. The use of microbial fermentation technology to process crop straw can not only solve the shortage of protein feed resources, but ...
