Embodiment 1
[0053] The site was selected for trial operation in Hunan Liangping Biotechnology Co., Ltd., Changsha City, Hunan Province. The soybean meal raw material was obtained from Hunan Liangping Agriculture and Animal Husbandry Development Co., Ltd. Specific steps are as follows:
[0054] S1, preparation bacterial enzyme, concrete operation is as follows:
[0055] 1) Obtain the required fermentation strains: Take 1g each of Baiyunbian distillery koji, vegetable garden soil, and Baiyunbian distillery pit mud in a 100mL Erlenmeyer flask, add PDA medium for enrichment and culture for 12 hours, dilute and spread, pick For a single colony, add 1% milk powder or 1% soluble starch to the plate, and screen the strains with transparent circles around the colonies, which are strains with high protease or amylase production respectively, and its 28ITS DNA is verified as Aspergillus oryzae (MQ) by PCR amplification and sequencing , Aspergillus niger (HQ), yeast (YT) strains.

Abstract
The invention relates to a production method of an anti-mildew and anti-sticking feed. The production method comprises the following steps: 1, treating a main material: crushing the main material namely soybean meal, and screening with a 60-mesh screen; 2, mixing: uniformly mixing fermentation inoculant with water, bacterial enzyme and the main material according to a ratio of (0.1-0.2%): (30-40%): (1-5%): (55-68%); and 3, fermenting: putting the uniformly mixed raw materials into a polyethylene plastic bag, sending the polyethylene plastic bag into a fermentation workshop for constant-temperature fermentation at 28 DEG C, enabling aerobic bacteria to play a role in the first 2 days, after oxygen is exhausted in the later 3 days, enabling anaerobic bacteria to begin to grow quickly, enabling the materials to begin to be acidified, and obtaining a fermented feed finished product after 5-7 days. According to the invention, strain types are innovated, strain resources capable of directionally inhibiting mould growth and enabling fermentation products to be non-sticky are added, and an aerobic and anaerobic combined fermentation system is adopted, so that the problems of high viscosityand easiness in mildewing of wet fresh fermented soybean meal are solved, the fermentation level of the wet fresh soybean meal is improved by a new height, and the utilization rate of the wet fresh soybean meal is greatly increased.
Description
technical field [0001] The invention relates to the field of feed processing, in particular to a production method of anti-mildew and anti-sticking feed. Background technique [0002] Feed fermentation refers to the fermented feed made by mixing and fermenting the feed with microorganisms (lactobacillus, yeast and bacillus, etc.). Studies have found that Lactobacillus reproduces faster in solid culture and produces a large number of metabolites, including lactic acid, antibacterial peptides, biotin, etc. Strong antibacterial effect; Yeast plays a certain role in improving animal immunity, improving animal production performance and reducing stress; Bacillus can use macromolecular proteins, starch and non-starch polysaccharides to decompose into small molecular substances, It can decompose tryptophan to form indole, and can generate a lot of heat under the condition of sufficient oxygen, and its metabolites are mostly enzymes, among which Bacillus subtilis can form α-amylase...
