Problems solved by technology

Therefore, there is an urgent need for a antibiotic-free feed that can be applied on a large scale in actual production. However, the current research on antibiotic-free feed is produced by microbial fermentation, and the production or storage process of antibiotic-free feed by microbial fermentation is complicated. It is incompatible with the production process of today's feed industry, and it is not easy to realize industrialized feed production and promotion

Embodiment １

[0026] Slant medium: 1.0% glucose, 1.0% corn steep liquor, 2.0% agar, pH 7.5, sterilized at 115°C for 20 min.

[0027] Liquid medium: 2.0% glucose, 1.0% corn steep liquor, 0.1% magnesium sulfate, pH 7.5, sterilized at 115°C for 20 min.

[0028] Streptomyces albus Streptomyces. albulus The spores were inserted into the slant medium and cultured at 30°C for 7 days to obtain the strain slant; then a ring of slant strains was inserted into the liquid medium and cultured at 30°C for 1 day to obtain the microbial culture solution.

[0029] Mix 200 g of corn bran, 180 g of corn germ meal, 100 g of corn steep liquor (dry matter), and 110 g of protein powder. Take 500ml of microbial culture solution and add it to the mixed material. At this time, the water content of the material is greater than 40%. Use 25% ammonia water to adjust the pH of the material to 5.5, and treat it at 35°C for 2 days. The pH is not adjusted during the entire fermentation process, and it naturally decreases ...

Embodiment 2

[0031] 300g soybean meal, 300g DDGS. Take 500 ml of microbial culture solution and add it to the mixed material. At this time, the water content of the material is greater than 40%. It should be noted that the microorganisms added to the material except Streptomyces albicans Streptomyces. albulus , but also add Bulgarian lactic acid bacteria and Candida utilis, both lactic acid bacteria and yeast are commercially available starters. Adjust the pH of the material to 5.5 with 25% ammonia water, and treat it at 35°C for 2 days. The pH is not adjusted during the entire fermentation process, and it naturally decreases with it. The pH is reduced to 5.0 in 12 hours of fermentation, and to 4.5 in 24 hours. At this time, no ε-polylysine can be detected in the material. When fermenting for 36 hours, the pH decreased to 4.2 with 50 mg / kg of ε-polylysine, and at 48 hours, the pH decreased to 3.7 with 100 mg / kg of ε-polylysine and 100 The feed product was obtained after drying at ℃. ...

Embodiment 3

[0033] The process of preparing the fermented feed is the same as in Example 1; it should be noted that the corn bran and germ meal should be crushed to below 80 mesh in advance; The protein feed can be fed to fish.

Abstract

The invention discloses a production method of an antibiotic-free feed. An epsilon-polylysine producing strain is inoculated in the production process of a fermented feed; and the finally obtained feed product contains 1-300mg / kg of epsilon-polylysine. The feed does not contain an antibiotic, is capable of effectively resisting and preventing diseases when fed to livestock, is also capable of avoiding conventional infectious microbe pollution, and can be produced and applied on a large scale; and the production performance of animals can be taken into account.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a production method of antibiotic-free feed. Background technique [0002] The spoilage of feed can cause huge economic losses, how to prevent spoilage is a problem that those skilled in the art are most concerned about. At present, the commonly used antiseptic measure is to add feed preservatives. Feed preservatives are divided into chemical preservatives, natural preservatives and compound preservatives, among which chemical preservatives are the most widely used. With the gradual improvement of people's awareness and requirements for food safety, chemical preservatives are faced with severe challenges, and the naturalization of feed anti-mold preservatives has become a development trend in the future. [0003] Feed antibiotics have played a positive role in preventing feed spoilage, preventing animal diseases, and promoting animal growth. However, with the widespread ...
