Problems solved by technology

However, due to the existence of anti-nutritional factors (anti-urease, trypsin, etc.) in soybean meal; factors such as free gossypol and cycloacrylic acid in cotton meal; substances such as sinigrin, erucic acid, phytic acid and tannin in rapeseed meal, these all affect The normal application of these three major meal types has brought inconvenience to the production of feed

Embodiment 1

[0014] A method for detoxification and fermentation of feed meal, the specific steps are as follows:

[0015] Step 1, raw material screening: remove moldy and rotten raw materials, mix and pulverize them evenly according to the weight ratio of soybean meal: cotton meal: rapeseed meal is 3:1:1;

[0016] Step 2, fermentation: select 6 kg of mixed strains containing Bacillus subtilis, lactobacillus and saccharomyces, the strain content in the mixed strains is 18 billion / g, 10 kg of culture medium, pretreatment at a temperature of 36 degrees Celsius for 14 hour, obtain the activated bacteria enrichment liquid, add 415 kilograms of water, add the water enriched bacteria liquid to the 1000kg meal mixer prepared in advance, mix for 6 minutes, store the mixed meal in an airtight container, under natural conditions Sealed fermentation for 2.5 days, until the surface fermentation is completed when there is alcohol or earthy smell;

[0017] Step 3, low-temperature drying: drying the fer...

Abstract

The invention discloses a detoxification and fermentation method for meal for feed. The method comprises the following specific steps: (1) eliminating mildewy and degenerative raw materials, uniformly mixing soybean meal, cottonseed meal and rapeseed meal according to the weight ratio of (3 to 5):1:1, and carrying out crushing; (2) selecting 5kg to 10kg of mixed strains, pretreating the mixed strains for 12 to 16 hours so as to obtain activated strain enrichment broth, adding 400kg to 450kg of water, adding the water added strain enrichment broth into a mixer containing 1,000kg of pre-prepared meal, carrying out mixing for 5 to 8 minutes, storing the mixed meal in a closed vessel, and carrying out closed fermentation under natural conditions; (3) drying the fermented material in a low-temperature dryer until the moisture content is 8% to 9%, thereby obtaining detoxified mixed meal. According to the method, the content of total protein is increased, so that the meal can be extensively applied to the feed; the product is good in palatability, and fermented products are small-peptide proteins and amino acids and are more easily absorbed and utilized by animals so as to provide healthy gastrointestinal tracts for the animals.

Description

technical field [0001] The invention relates to the field of feed production, in particular to a method for detoxifying and fermenting feed meal. Background technique [0002] With the improvement of people's living standards, people's demand for various foods has greatly increased, and aquaculture has become a way for many people to make a fortune. The most important thing in the breeding industry is the feeding of farmed animals. Breeding refers to the feeding and care of animals, and food for other animals. Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. The feed includes more than ten varieties of feed materials such as soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additive, whey powder, oil, meat and bone meal, grain, and sweet sorghum. Soybean meal, cotton meal and rapeseed meal are the three major meal typ...
