Embodiment 1

[0037] A biological protein feed made of cellulose raw materials, wherein the organic materials include: cellulose raw materials (corn stalks, corncobs, straw, cassava residues and pomace): 85 parts, rapeseed meal: 5 parts, bran: 10 parts (parts by weight).

[0038] The composite bacteria include: Bacillus subtilis, saccharomyces, lactic acid bacteria and cellulolytic bacteria (such as Trichoderma, white rot fungus, etc.); the above bacteria are mixed in a weight ratio of 2:1:1:3. The added amount of complex bacteria is 10% (percentage by weight) of the organic material. The cultivation methods of each strain in the composite bacteria are conventional methods.

[0039] The biological protein feed is prepared according to the following process:

[0040] (1) crushing the cellulose raw material to particles with a diameter of 2 to 3 mm;

[0041] (2) Putting the pulverized cellulose raw material into an extruder to expand;

[0042] (3) According to the proportioning ratio of e...

Abstract

Disclosed is biological protein feed made from a cellulose raw material. The feed is composed of an organic material and compound bacteria. The weight of the compound bacteria is 1-10% of the weight of the organic material. The organic material is composed of the cellulose raw material, rapeseed meal and bran. The cellulose raw material is one or more of corn straw, corn cob, rice straw, cassava residue and fruit residue. The compound bacteria is composed of bacillus subtilis, yeast, lactic acid bacteria, and cellulose decomposing bacteria. The cellulose decomposing bacteria are one or more oftrichoderma and white rot fungi. In the biological protein feed, the content of probiotics is greater than 108 cfu / g, and a plurality of proteases, cellulases and amylases are contained. The preparation process is simple and the fermentation period is short. The invention also discloses a preparation method of the feed.

Description

technical field [0001] The invention relates to a feed for livestock, poultry and aquatic products, in particular to a biological protein feed which takes cellulose raw material as the main raw material and is fermented with compound bacteria. Background technique [0002] At present, the existing livestock, poultry, and aquatic animal feeds are generally mainly composed of grain raw materials, fish meal, appropriate amount of amino acids and trace elements. Among them, the commonly used grain raw materials mainly include crops such as corn, sorghum, beans, and wheat. The demand for food is large, the cost is high, and it is easy to cause food shortage. Therefore, people have been researching various alternative products to replace grain feed, so as to save costs and improve utilization efficiency. Chinese patent application CN1813562A (application number 200510019197.4, published on August 9, 2006) discloses a compound microbial fermented feed nutritional additive and its ...
