Embodiment 1

[0089] Embodiment 1: a kind of feed additive formula based on earthworm fermented liquor:

[0090] A kind of feed additive based on earthworm fermented liquor, described feed additive comprises:

[0091] Earthworm broth as a base component; and

[0092] Amino sugar oligomer (ASO-x) and sodium metabisulfite complex as a synergistic component;

[0093] Wherein, the amino sugar oligomer is a product of chitosan degraded by Aspergillus luteus, and its degree of deacetylation is not higher than 61%, and the content of free amino groups is not higher than 5.5%;

[0094] The sodium metabisulfite complex consists of a core particle comprising sodium metabisulfite and an enteric coating covering the core ion; and

[0095] The mass ratio of the amino sugar oligomer to the sodium pyrosulfite complex is 4:1;

[0096] The sum of the mass of the amino sugar oligomer and sodium pyrosulfite complex accounts for 10% of the feed additive.

[0097] Specifically, the feed additive based on ...

experiment example 1

[0128] Experimental Example 1: Detection of physicochemical properties of amino sugar oligomers in Example 1:

[0129] A respectively with the chitosan of step 2) when preparing amino sugar oligomer in embodiment 1 and the final product amino sugar oligomer are dissolved with 0.5mol / LHCl to make 1% solution, measure chitosan with Ubbelohde viscometer The relative viscosity of sugar and amino sugar oligomer, the result shows, the reduced viscosity of chitosan is 35dl / g, and the reduced viscosity of amino sugar oligomer is 0.05dl / g, and rate of decline is 99.86%, and amino Sugar oligomer has a certain solubility in the whole range of pH value, and the solution state is stable, which greatly expands the solubility range of chitosan, which can make it more convenient to add to feed additives, and at the same time provide absorbed and utilized.

[0130] B analyzes the characteristic groups of chitosan and amino sugar oligomers by Fourier transform infrared spectrometer, and the ...

Embodiment 2

[0135] Embodiment 2: another kind of feed additive formula based on earthworm fermented liquid:

[0136] This example provides another feed additive formula based on earthworm fermented liquid, the formula and preparation method of which are basically the same as in Example 1, except that the feed additive in this embodiment only contains earthworm fermented liquid as a basic component.

Abstract

The present invention relates to an earthworm fermentation liquid-based feed additive, and a preparation method and an application thereof. The feed additive comprises earthworm fermentation liquid asa basic component, and an amino sugar oligomer and a sodium metabisulfite compound as a synergistic component; the amino sugar oligomer is a product of chitosan degraded by aspergillus tamarii; the sodium metabisulfite compound is composed of core particles containing sodium metabisulfite and an enteric coating coating the core particles; and a mass ratio of the amino sugar oligomer to the sodiummetabisulfite compound is (4.0-4.5):1. The feed additive has significant benefits for growth and fattening, survival rate and immune system of livestock and poultry animals, significantly reduces occurrence of toxic effects such as decreased feed intake, growth rate, immunity and survival rate of livestock and poultry caused by vomiting toxins, and can more efficiently improve animal production efficiency.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive based on earthworm fermentation broth, a preparation method and application thereof. Background technique [0002] Feed additives refer to small or trace substances added during feed production, processing and use, which are used in small amounts but have significant effects in feed. Feed additive is an inevitable raw material used in the modern feed industry. It has obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving animal product quality. Feed additives are divided into microbial feed additives and Chinese herbal medicine feed additives. Among them, the microbial feed additive is a microbial product that replaces or balances one or more strains of bacteria in the animal ecosystem. In a narrow sense, it is a microbial product that can stimu...
