Embodiment 1

[0025] A method for producing straw feed, the steps are as follows:

[0026] 1) Crushing the straw into straw particle raw materials with a particle size of 0.2-1.0cm;

[0027] 2) Part of the raw material of straw pellets was ammonified with an ammonia solution with a concentration of 5% by weight at 30°C for 6 weeks to obtain ammoniated straw;

[0028] 3) Add plant lactic acid bacteria (Lactobacillus, CGMCC.155) to some straw pellet raw materials for silage treatment. The inoculum amount of plant lactic acid bacteria is 2% of the weight of the straw raw material, and react for 30 days at room temperature to obtain silage straw;

[0029] 4) Mix the partially ammonified straw with corn cob particles with a particle size of 1.0-2.0cm evenly, add water to make the moisture content of the material 65%, and add a lactic acid solution with a concentration of 20% by weight to reduce the pH of the mixed material. Adjust it to 6, add Aspergillus niger and Bacillus subtilis mixed ferme...

Embodiment 2

[0033] A method for producing straw feed, the steps are as follows:

[0034] 1) Crushing the straw into straw particle raw materials with a particle size of 0.2-1.0cm;

[0035] 2) Part of the raw material of straw pellets was ammonified with a urea solution with a concentration of 6% by weight at 30°C for 7 weeks to obtain ammoniated straw;

[0036] 3) Add plant lactic acid bacteria (Lactobacillus, CGMCC.155) to some straw pellet raw materials for silage treatment. The inoculum amount of plant lactic acid bacteria is 2% of the weight of the straw raw material, and react for 30 days at room temperature to obtain silage straw;

[0037] 4) Mix the above partly ammonified straw with corn cob particles with a particle size of 1.0-2.0cm, add water to make the moisture content of the material 60%, add 20% acetic acid solution by weight to adjust the pH of the mixed material Adjust it to 6, add Aspergillus niger fermentation inoculum to the mixed material, mix evenly, then ferment fo...

Abstract

The invention relates to a production method of straw feed, comprising the following steps: 1) smashing straw into particle materials; 2) carrying out ammoniation treatment on part of the straw particles with ammonia water or urea solution to obtain ammoniated straw; 3) adding plant lactic acid bacteria to the part of straw particle material for silage treatment so as to obtain silage straw; 4) adding water to uniformly mix the part of ammoniated straw with corncob particle, adding lactic acid or acetum to regulate the pH to 5-6, adding zymophyte solvent and uniformly mixing, and carrying out fermentation to obtain a straw degeneration enzyme strain; 5) uniformly mixing the ammoniated straw, the silage straw and the straw degeneration enzyme strain, adding a zymophyte solution, and carrying out fermentation to obtain a water-containing straw yeast; and 6) drying or pelleting the yeast to obtain the straw feed. The production method has the advantages that high-efficient fiber lignin degradation bacterium is adopted to produce the straw degeneration enzyme strain, and the degeneration efficiency and the nutrient content in feed are improved; equipment needed for material fermentation is simple, the operation is simple and convenient, and the cost for producing feed is lowered.

Description

technical field [0001] The invention relates to a production method of livestock feed, in particular to a production method of straw feed. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's dietary structure is also gradually changing, and the proportion of meat, eggs and milk is constantly increasing. According to the statistics of relevant departments, the total output of my country's meat and eggs has ranked first in the world at present, and the per capita share has reached the world average level. For animal husbandry, the cost of feed accounts for more than 70% of the total cost, of which grain feed accounts for more than 90% of conventional feed. Therefore, with the continuous increase of people's demand for animal products, the feed gap will continue to increase, and the global price of grain The rise has prompted the cost of animal husbandry to rise again. [0003] ...
