Embodiment 1

[0030] Ginger extract is made through the following steps:

[0031] After washing the ginger slices, dry them in an oven at 60°C for 9 hours to obtain dried ginger slices; grind the dried ginger slices with a pulverizer to obtain ginger powder; mix ginger powder and ethanol at a mass ratio of 1:45, Stir in a water bath at ℃ for 2 hours to obtain a ginger extract; condense the ginger extract by rotary evaporation at 65 °C to one-tenth of the original volume to obtain the ginger extract.

Embodiment 2

[0033] Scutellaria baicalensis extract is made through the following steps:

[0034] Wash and chop Scutellaria baicalensis, mix according to the mass ratio of Scutellaria baicalensis and water 1:9, heat to boiling, keep warm for 1 hour, keep warm at 70°C for 4 hours, filter to obtain the filtrate, repeat the above operation on the filter residue, and finally combine the filtrate, When the filtrate is concentrated to one-fifth of the original liquid volume, add ethanol to the original liquid volume, ultrasonically disperse for 40 minutes, let stand for 30 minutes, filter, obtain the filtrate and concentrate it to one-fifth of the original liquid volume, repeat the above The operation was performed twice, and when the finally obtained filtrate was concentrated to one-fifth of the original liquid volume, the pH value was adjusted to 1 with citric acid, kept at 60° C. for 3 hours, filtered, and dried to obtain the Scutellaria baicalensis extract.

Embodiment 3

[0036] Core particles are made by the following steps:

[0037]Step A, first 50 parts by weight of wine lees are subjected to steam explosion pretreatment; the treatment intensity of steam explosion is 4MPa, and the treatment time is 3min, thereby reducing the fiber content in wine lees; wine lees after explosion, 17 parts by weight of wheat bran and After mixing 9 parts by weight of rapeseed meal, a premix is ​​obtained, and mixed bacteria and compound enzymes are added to the premix for solid-state anaerobic fermentation; the fermentation conditions are: material-to-water ratio 1:1, temperature 28°C, inoculation amount of mixed bacteria For 0.05% intervening mixture weight, compound enzyme addition 0.05% intervening mixture weight, fermentation time is 7 days, obtains the premix after fermentation, and described mixed bacterium is aspergillus niger and candida utilis according to mass ratio 2: 0.5 for a mixed combination, the strains used are the probiotics allowed to be use...

Abstract

The invention discloses a natural antibiotic-replacing feed additive and a preparation method thereof, and belongs to the technical field of feed processing. The natural antibiotic-replacing feed additive comprises inner core particles and a wrapping layer. The mixed bacteria and the compound enzyme are used for fermenting the wine vinasse, so that the soluble nitrogen content of the wine vinasse is increased, the quality of the wine vinasse is better, and the nutrition is more balanced; meanwhile, the ginger extract and the radix scutellariae extract are introduced, so that the obtained core particles have excellent antibacterial performance while having rich nutritional value; modified chitosan and sodium alginate are used as film-forming base materials, sodium tripolyphosphate is used as a cross-linking agent, so that the obtained natural antibiotic-replacing feed additive has slow-release performance, and chitosan is subjected to grafting modification of organic silicon, so that a siloxane chain layer is gathered on the surface of a slow-release film, the mechanical property of the film is improved, the slow release performance of the additive is further improved.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a natural antibiotic feed additive and a preparation method thereof. Background technique [0002] Antibiotics as feed additives can promote animal growth and disease prevention and control, but the extensive use of antibiotics in production can lead to the emergence of bacterial resistance, drug residues in meat and meat products, and other problems, endangering animal and human health. Antibiotic-free feed and natural and safe growth promoters are an important topic in the animal meat, eggs and dairy products market. In production practice, some people are already reducing the use of antibiotics by using a variety of alternatives. [0003] At present, spray-dried plasma protein powder, Chinese herbal medicine and its extracts, probiotics, prebiotics, and egg yolk antibodies can be used as feed additives instead of antibiotics. The advantages of not easy to...
