Abstract

The invention provides a plant essential oil feed additive. The additive comprises a core material and a wrapping material wrapping the core material; the core material is prepared from thymol, carvacrol, microcrystalline cellulose and silicon dioxide; the wrapping material is a single coating layer formed by any kind of coating of methacrylic acid-ethyl acrylate copolymer aqueous dispersion, ethyecellulose or hydroxypropyl methyl cellulose, or a double coating layer formed by coating ethyl cellulose and hydroxypropyl methyl cellulose respectively. Accordingly, microcrystalline cellulose serves as an insoluble framework material, different materials of the methacrylic acid-ethyl acrylate copolymer aqueous dispersion, ethyecellulose and hydroxypropyl methyl cellulose serve as the wrapping material, and a fluidized bed is adopted for coating thymol and carvacrol, volatilization loss of thymol and carvacrol is reduced, the effectiveness of the effective ingredients in the additive to foodanimals is guaranteed, and the effect of improving the action of the additive is improved.

Description

technical field

[0001] The invention belongs to the technical field of feed additives, in particular to a plant essential oil feed additive and its preparation method and application. Background technique

[0002] In animal husbandry production, antibiotics are widely and long-term added to livestock and poultry diets as disease-resistant and growth-promoting agents to improve the high morbidity and mortality of livestock and poultry during the feeding process. While achieving great results, it has also caused serious problems such as bacterial resistance, multi-drug resistance and antibiotic residues, threatening human food safety and human health. Therefore, finding and applying safe and effective alternatives to antibiotics is the primary goal at present. Prebiotics, probiotics, organic acids, enzyme preparations and plant-derived feed additives are currently highly recognized. Plant-derived additives are gradually emerging in the animal husbandry industry because of the...
