Problems solved by technology

However, plant essential oil is a kind of broad-spectrum antibacterial active ingredient. When it works in the intestinal tract of animals, it not only acts on intestinal pathogenic bacteria, but also kills the probiotics existing in the intestinal tract to a certain extent, resulting in an imbalance of intestinal flora

preparation example Construction

[0031] The present invention also provides a preparation method for the above-mentioned feed additive. In order to improve the solubility of cinnamon essential oil, acetic acid and mannan oligosaccharides and make them better mixed, cinnamon essential oil and acetic acid are firstly used in the feed additive of the present invention. Alcoholic solution is diluted, and then mixed between the components.

[0032] In the present invention, the preparation process is preferably the following steps:

[0033] Mixing cinnamon essential oil and alcohol solution to obtain cinnamon essential oil-alcohol solution;

[0034] Mix acetic acid and alcohol solution to obtain acetic acid-alcohol solution;

[0035] The cinnamon essential oil-alcohol solution, acetic acid-alcohol solution, mannan oligosaccharide and maltodextrin are mixed.

[0036] Further, the alcohol solution includes: one or both of absolute ethanol, propylene glycol and glycerin.

[0037] Furthermore, the mass percentage c...

Abstract

The present invention belongs to the field of compositions and particularly relates to a composition and a feed additive and preparation methods thereof. The provided feed additive comprises cortex cinnamomi essential oil, acetic acid and mannan oligosaccharide, wherein the cortex cinnamomi essential oil has volatility and broad spectrum antibacterial activity, the acetic acid can maintain gastrointestinal acid-base balance, inhibit harmful bacteria and promote probiotics growth, and a combination of the acetic acid and cortex cinnamomi essential oil enhances antibacterial effect of the composition, reduces harm of the cortex cinnamomi essential oil on the gastrointestinal probiotics, and promotes gastrointestinal absorption; and at the same time, the three materials of the cortex cinnamomi essential oil, acetic acid and mannan oligosaccharide are reasonable in compatibility, have synergies, improve effects of the composition in inhibiting growth of intestinal pathogens, enhance body immunity functions and protect the intestinal probiotics. The feed additive is simple in preparation method, low in costs of the components, can effectively replace feed antibiotics applied in aquaculture industry, and reduces production costs.

Description

technical field [0001] The invention belongs to the field of compositions, and in particular relates to a composition, a feed additive and a preparation method thereof. Background technique [0002] Animal intestinal flora is a complex micro-ecosystem composed of probiotics, opportunistic pathogens and pathogenic bacteria, with more than 1000 types of microorganisms. Among them, probiotics mainly include Lactobacillus and Bifidobacterium, etc. Escherichia coli is the most common intestinal pathogen that causes diarrhea. The most common of these is Aspergillus flavus. The main function of antibiotics in the intestinal tract of animals is to regulate the intestinal flora, and it has no significant effect on the growth of probiotics while inhibiting the growth of pathogenic bacteria. Because of its good antibacterial activity, feed antibiotics have promoted the rapid development of livestock and poultry farming since the 1950s. It plays an active role in promoting animal grow...
