Problems solved by technology

However, traditional physical and chemical methods for removing mycotoxins have disadvantages such as unstable effects, large loss of nutrients, affecting feed palatability, and difficulty in large-scale production.
For example, physical adsorption methods such as activated carbon method and silicate method, which adsorb a large amount of vitamins and amino acids while adsorbing mycotoxins, have poor application effects and too much addition, and occupy a large proportion of feed ratio, so it is difficult to be absorbed Widely used in actual production

Embodiment 1

[0050] Firstly, 5kg of fresh wheat bran was weighed as the fermentation base material, and then prepared with 2×10 7 cfu / mL yeast NKY1, 2×10 7 cfu / mL Bacillus subtilis, 2×10 7 cfu / mL Bacillus licheniformis, 2×10 7 cfu / mL Lactobacillus plantarum, 2×10 7 cfu / mL Lactobacillus reuteri LR1 mixed bacterial solution 5.0L, stir evenly, spray the mixed bacterial solution into the bran raw material, mix the material solution well, put the fermented base material after inoculation into the microorganism with one-way ventilation valve In the anaerobic fermentation bag, heat-melt the seal, place the fermentation bag in an environment of 32° C. for 48 hours to ferment for 48 hours, and obtain fermented fiber feed for pigs. After fermentation, the material was sampled to determine the number of live bacteria (plate count method), material pH, lactic acid content, mycotoxin content and protein content of Bacillus, Lactobacillus and yeast respectively. The results are shown in Table 1.

Embodiment 2

[0061] Take by weighing fresh 4.5kg wheat bran and 0.5kg bean curd, mix well. Then make up 2 x 10 7 cfu / mL yeast NKY1, 2×10 7 cfu / mL Bacillus subtilis, 2×10 7 cfu / mL Bacillus licheniformis, 2×10 7 cfu / mL Lactobacillus plantarum, 2×10 7 cfu / mL Lactobacillus reuteri LR1 mixed bacterial solution 5.0L, stir well. Spray the mixed bacteria solution into the bran raw material, mix the material solution fully and evenly, put the fermented base material after inoculation into a microbial anaerobic fermentation bag with a one-way ventilation valve, seal it with hot melt, and place the fermentation bag in an environment of 32°C The fermented fiber feed for pigs was obtained by standing and fermenting for 48 hours. After fermentation, the material was sampled by measuring the number of live bacteria of Bacillus, Lactobacillus and yeast (plate count method), the pH value of the material, the content of lactic acid, the content of mycotoxin, and the content of protein. The results are ...

Embodiment 3

[0066] Take by weighing fresh 4.0kg wheat bran and 1.0kg bean curd, mix well. Then make up 2 x 10 7 cfu / mL yeast NKY1, 2×10 7 cfu / mL Bacillus subtilis, 2×10 7 cfu / mL Bacillus licheniformis, 2×10 7 cfu / mL Lactobacillus plantarum, 2×10 7 cfu / mL Lactobacillus reuteri LR1 mixed bacterial solution 5.0L, stir well. Spray the mixed bacteria solution into the bran raw material, mix the material solution fully and evenly, put the fermented base material after inoculation into a microbial anaerobic fermentation bag with a one-way ventilation valve, seal it with hot melt, and place the fermentation bag in an environment of 32°C The fermented fiber feed for pigs was obtained by standing and fermenting for 48 hours. After fermentation, the material was sampled by measuring the number of live bacteria of Bacillus, Lactobacillus and yeast (plate count method), material pH value, lactic acid content, mycotoxin content, and protein content. The results are shown in Table 3. The detection...

Abstract

The invention discloses fermented fiber feed for pigs and a preparation method thereof. The fermented fiber feed for the pigs takes bran and the like as raw materials, and yeasts, bacillus subtilis, bacillus licheniformis, lactobacillus plantarum, lactobacillus reuteri, and other probiotics are selected for compatibility as fermentation bacteria, and a multi-strain mixed fermentation process is adopted. Catabolism of microorganisms can reduce toxin content in fiber materials, increase protein content in fiber materials, and increase nutritional value of fiber materials. Secondly, various kindsof probiotics for compatibility are selected as fermentation bacteria. After solid-state fermentation of bran and other raw materials, the biological feed contains a large number of probiotics capable of improving intestinal health of animals, and the biological feed can improve micro-ecological environment of a gastrointestinal tract after animals are fed. Body's immunity is improved. In addition, the biological feed is rich in lactic acid and very mellow, palatability of the feed can be significantly improved, animal feed intake is increased, rapid growth of animals is promoted, and production capacity of an aquaculture industry is increased.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a fermented fiber feed for pigs and a preparation method thereof. Background technique [0002] Animal guts contain a large number of symbiotic microorganisms, which are closely related to the health of animals. They participate in many important physiological functions, such as food digestion and metabolism, and help the host resist infection and so on. For intestinal bacteria, sufficient dietary fiber is the key to maintaining the balance of intestinal flora and promoting intestinal microorganisms to perform their physiological functions. Dietary fiber refers to the general term for polysaccharide carbohydrates and lignin that are not digested by animals. Most dietary fiber is not easily absorbed and utilized by animals, but this part of food is indeed an important energy source for gut microbes. Studies have shown that when the host intakes insufficient dietary fiber, the intes...
