Embodiment 1

[0019] 1. Bacillus (producing protease, amylase, cellulase, peptide antibiotics, etc.) flora liquid seed fermentation steps are as follows:

[0020] 1) Activation of seed mothers: move Bacillus pumilus (for example: Bacillus pumilus, Bacillus subtilis, Bacillus sp., Paenibacillus amyloliguefaciens) seed mothers to the slopes of the newly prepared PDA medium respectively, and activate and cultivate for 24--48 hours , the temperature is 28°C, and the thalline in the activated and mature Kelvin flask is called a seed;

[0021] Seed parent activation culture adopts potato-sucrose agar medium (abbreviated as PDA medium) to form by weight percentage: 1000mL of 20% potato (potato) extract; 20g of sucrose, 18g of agar, pH7.0~7.2;

[0022] 2) Seed tank inoculation and fermentation culture: wash 1 bottle of Bacillus seeds in the activated Kjeldahl flask with 200mL sterile water into a 500mL sterile Erlenmeyer flask, and inoculate to 50mL by flame inoculation method or differential press...

Abstract

The present invention utilizes the crop waste material straw and stalk as raw material and adopts the bacillus, photosynthetic bacterium, microzyme, Aspergillus oryzae and seed liquor of basidiomycetes as beneficial microbial pool, and makes inoculation at room temp. to make the straw and stalk undergo the process of solid fermentation so as to obtain microbial fermented feed.

Description

technical field [0001] The invention relates to microbial fermented feed, in particular to a production method of straw microbial fermented feed. Background technique [0002] With the development of society and the improvement of people's living standards, people's demand for meat, eggs, poultry, aquatic products and other products is increasing day by day. The domestic and foreign consumer markets are huge, and the corresponding feed consumption is also increasing year by year. Crop stalks and other organic matter are fully utilized in developed countries. According to statistics from the United Nations Food and Agriculture Organization, 73% of meat in the United States is transformed from grass, 90% in Australia and New Zealand; and only 8% in my country; Biological resources are very rich. There are hundreds of millions of tons of stalks of various crops every year, and only a small part is used. Most of the stalks are burned, which not only wastes resources, but also cau...
