Embodiment 1

[0022] The present invention will be further elaborated below through specific examples. It should be noted that the following descriptions are only for explaining the present invention, and do not limit its content.

[0023] 1. Fermentation strains:

[0024] Aspergillus candidus is a strain numbered CICC40217 in China Industrial Microorganism Culture Collection Center; it is rich in cellulase, glucoamylase and protease.

[0025] Candida utilis (Candida utilis) is the strain numbered CICC1314 of the China Industrial Microorganism Culture Collection and Management Center; the bacterium is high-quality protein, high in vitamin B, and can utilize five-carbon sugars and six-carbon sugars.

[0026] Lactobacillus plantarum (lactobacillus plantarum) is a strain numbered CICC20764 by the China Industrial Microbiology Culture Collection Management Center; it has antiseptic, promotes the absorption of nutrients, and maintains the balance of intestinal flora.

[0027] 2. Medium:

Embodiment 2

[0040] Embodiment 2: Multifunctional bacterial fermentation compound protease feed related index detection

[0041] The edible fungus slag prepared in Example 1 of the present invention was re-fermented for crude protein, crude fat, crude fiber, and other indicators and the cow feeding test was compared with unfermented feed. The results are shown in Table 1-4.

[0042] Determination of protein content in bacterial residue before and after table 1 fermentation

[0043]

[0044] Table 2 Crude fiber content of fungus residue before and after fermentation

[0045]

[0046] Table 3 Crude fat content of bacteria residue before and after fermentation

[0047]

[0048] From Tables 1, 2, and 3, it can be seen that the protein content before and after fermentation has been significantly increased, the unutilized cellulose has been significantly reduced, and the crude fat has also decreased, which is of great significance for the improvement of feed quality.

Embodiment 3

[0055] The processing steps are the same as in Example 1, except that the edible mushroom is Pleurotus eryngii.

Abstract

The invention relates to a novel method utilizing edible fungus residues to produce a dairy cattle protein feed through fermentation. The novel method comprises the following steps that 1, seed liquid is prepared: saccharomycetes 1, aspergillus 1 and lactic acid bacteria 1 are amplified and cultured respectively in culture mediums containing a carbon source, a nitrogen source and a restrictive nutrient source to obtain the seed liquid; 2, the edible fungus residues are processed: 30-40 parts of dried edible fungus residues, 45-55 parts of water, 1-5 parts of bran and 0.5-1 part of sugar (water adding is not needed for wet edible fungus residues) are mixed and stirred evenly; 3, the seed liquid obtained in the step 1 is inoculated in the edible fungus residues, the total inoculating quantity is 5-10%, and stationary culture is performed at the temperature of 35 DEG C for 5-7 days to obtain the dairy cattle protein feed. The protein content of the fungus residues is remarkably improved by utilizing microorganisms to ferment the edible fungus residues, coarse fiber can be converted into fiber which can be utilized by dairy cattle, waste produced in edible fungus production can be well utilized, corresponding economic value is created, and resources can be well recycled.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a new method for producing dairy cow protein feed by fermenting edible fungus residues. Background technique [0002] my country is a country with a shortage of protein feed resources. At present, the annual shortage of protein feed is about 15 million tons. Therefore, the development of the protein feed industry in my country must take a road suitable for my country's national conditions, that is, to choose low-cost raw materials from a wide range of sources and low-cost processes to produce protein. feed. [0003] As a major producer of edible fungi, according to statistics, the total output of edible fungi in China reached 3.21×10 in 2013. 7 tons, with an output value of more than 140 billion. Along with the rapid development of the edible fungi industry, the amount of discarded solid medium after harvesting the fruiting bodies of edible fungi, that is, the number of ...
