Embodiment 1

[0038] A method for producing protein feed using crop stalks through multi-strain combined anaerobic fermentation, comprising the following steps:

[0039] (1) Preparation of stalk starter:

[0040] 1) The following microbial strains are selected as the bacterial source: Cellulomonas dinitrogena A1; Cellulomonas flavinogenes A2; Bacillus coagulans B1; Lactobacillus acidophilus B2; Bacillus subtilis C1; Bacteria D1; Propionibacterium D2; Candida Langcombe E1;

[0041] 2) The preparation process of straw starter is as follows:

[0042] Slope bacteria → liquid bacteria → first-level liquid culture → second-level liquid culture → third-level liquid

[0043] Cultivation → fermentation in fermenter → centrifugation → vacuum freeze drying → crushing →

[0044] A1, A2, B1, B2, C1, C2, D1, D2, E1, E2 and other ten strains of fermentation products

[0045] The materials are mixed evenly in different proportions → different straw starters are prepared;

[0046] The preparation proce...

Embodiment 2

[0057] The preparation of straw starter and straw treatment are the same as in Example 1; it should be noted that the temperature for producing straw protein feed by multi-strain combined anaerobic fermentation is at 35°C, and the protein content can be obtained in 7 days. 20% straw protein feed. The straw protein feed can be fed to ruminants such as cattle and sheep.

Embodiment 3

[0059] The preparation of straw starter and straw treatment are the same as in Example 1; it should be noted that the temperature for the production of straw protein feed by multi-strain combined anaerobic fermentation is at 20°C, and the protein content of 20-20% can be obtained in 20 days. 30% straw protein feed. The straw protein feed can be fed to ruminants such as cattle and sheep.

Abstract

A process for preparing straw (or stalk) protein feed of ox, sheep, pig, fish, chicken, etc by anaerobic fermentation of different bacteria is characterized by that 10 bacteria including Cellulomonas biazotea, Cellulomonas flave, Bacillus coagulans, acidophilous lactobacillus, hay bacillus, etc includes such steps as bacterial fermenting to obtain fermented liquid, vacuum freeze drying to obtain bacterial powder, and anaerobic fermenting of straw or stalk. Its advantages are high protein content, high appetite and preventing enterogastrosis.

Description

technical field [0001] The invention belongs to the technical field of protein feed produced by fermenting straw and other crop by-products, and in particular relates to the preparation of multi-strain straw starter and its anaerobic fermentation method for producing protein feed from straw and by-product of crops. technical background [0002] With the rapid development of my country's animal husbandry, the demand for feed has higher requirements in terms of quantity and variety. It is the development trend of feed industry to vigorously develop feed with high nutritional value and low production cost. As we all know, my country is a large agricultural country, with a total annual crop straw output of more than 700 million tons, including 230 million tons of rice straw, 220 million tons of corn stalks, 100 million tons of crop straws of beans and autumn miscellaneous grains, peanuts and potato vines, 100 million tons such as beet leaves, this is a huge bioavailable resource...
