Embodiment 1

[0063] Embodiment 1, the preparation of composite bacterial agent

[0064] The compound microbial agent for preparing fermented feed, its active ingredient is composed of Bacillus subtilis GCMCC1.0892, Saccharomyces cerevisiae CGMCC2.1190 and Lactobacillus acidophilus CGMCC1.1854, which is Bacillus subtilis The mixture obtained by mixing the liquid strain of Saccharomyces cerevisiae and the liquid strain of Lactobacillus acidophilus.

[0065] The liquid strain of Bacillus subtilis is a culture obtained by culturing at 34-35°C for 18-24h with nutrient broth medium, and the content of Bacillus subtilis in the liquid strain of Bacillus subtilis is 1.3×10 8 cfu / mL;

[0066] The liquid strain of Saccharomyces cerevisiae is a culture obtained by culturing wort medium at 31-33°C for 18-24h, and the content of Saccharomyces cerevisiae in the liquid strain of Saccharomyces cerevisiae is 4.8×10 8 cfu / mL;

[0067] The liquid strain of Lactobacillus acidophilus is a culture obtained by...

Embodiment 2

[0069] Embodiment 2, the preparation of fermented feed 1 and its functional verification

[0070] One, the preparation of fermented feed 1

[0071] The components and their mass ratios in the fermentation raw materials are as follows: 38 parts of corn fiber feed: 10 parts of corn dregs: 40 parts of corn flour: 5 parts of corn bran: 5 parts of rice bran: 2 parts of molasses. Add water to the fermentation raw material according to the mass ratio of 1.2:1 according to the ratio of material to water to obtain the fermentation medium, and sterilize it at 121° C. for 20 minutes. Add it into the fermentation medium, and ferment for 48 hours at a fermentation temperature of 35° C. to obtain a fermented feed 1 . The product quality is shown in Table 1 and Table 2: fermented feed 1 is rich in probiotics Bacillus subtilis, Saccharomyces cerevisiae and Lactobacillus acidophilus; crude protein content, polypeptide content, amylase activity and protease activity in fermented feed 1 , cell...

Embodiment 3

[0089] Embodiment 3, the preparation of fermented feed 2 and its functional verification

[0090] One, the preparation of fermented feed 2

[0091]The components and their mass ratios in the fermentation raw materials are as follows: 20 parts of corn fiber feed: 30 parts of corn dregs: 20 parts of corn flour: 10 parts of corn bran: 7 parts of rice bran: 3 parts of molasses. Add water to the fermentation raw material according to the mass ratio of 1.2:1 according to the ratio of material to water to obtain the fermentation medium, and sterilize it at 121° C. for 20 minutes. Add it into the fermentation medium, and ferment for 48 hours at a fermentation temperature of 35° C. to obtain a fermented feed 2. The product quality is shown in Table 5 and Table 6: fermented feed 1 is rich in probiotics Bacillus subtilis, Saccharomyces cerevisiae and Lactobacillus acidophilus; crude protein content, polypeptide content, amylase activity and protease activity in fermented feed 2 , cellu...

Abstract

The invention discloses a preparation method of corn processing by-product fermented feed and a used composite microbial agent. The fermented feed is prepared through fermentation of the composite microbial agent containing Bacillus subtilis, Saccharomyces cerevisiae and Lactobacillus acidophilus as well as fermentation raw materials, has a special sour and sweet smell, has good palatability and can be absorbed and utilized by animals easily. The increment of the daily milk yield of dairy cows fed with the fermented feed is increased, the number of somatic cells in milk is reduced, the average daily gain of each mutton sheep fed with the fermented feed is increased, animal waste has a good shape, and the ammoniac odor and other odors are reduced. Low-quality by-products produced during processing of corn are treated with the microbial fermentation technology, many macromolecular substances are degraded, biological feed products containing active substances such as probiotics, active enzymes and the like are obtained, waste is turned into wealth, protein resources are increased, grains are saved, and an effective path is provided for solving of the environmental pollution problem.

Description

technical field [0001] The invention relates to a preparation method of corn processing by-product fermented feed in the field of biological feed and a composite bacterial agent used. Background technique [0002] With the rapid development of my country's animal husbandry, people's dietary structure and animal food consumption have undergone significant changes. At the same time, the consumption of animal product production resources is also increasing year by year. It is the main factor restricting the development of animal husbandry in my country. At present, my country's annual feed consumption has exceeded 300 million tons, and China has become the world's largest feed consumer. The main problem faced by my country's feed industry is the lack of resources such as protein and energy feed, and its high dependence on imports, resulting in an increase in the cost of livestock and poultry breeding. Therefore, looking for high-quality feed substitute resources to improve the...
