Embodiment Construction

[0028] One, prepare chicken feed additive according to following raw material formula and preparation method:

[0029] The raw material components of the chicken feed additive and their weight proportions are: 20 parts of chitosan, 20 parts of xylo-oligosaccharide, 5 parts of Folium folium extract, 8 parts of dandelion extract and 8 parts of licorice extract. The average molecular weight of the chitosan is between 1000 and 50000.

[0030] The steps of the preparation method are:

[0031] a. Preparation of dandelion extract: crush the whole dandelion herb into 50 mesh particles, heat and extract with 10 times the weight of 70% ethanol by volume for 3 hours, concentrate under reduced pressure to 1 / 4 of the initial liquid volume, and spray dry to obtain the extract Particles were extracted three times in the same way.

[0032] b. Preparation of licorice extract: crush licorice into 50-mesh granules, heat and extract with 10 times the weight of water for 3 hours, concentrate und...

Abstract

The invention discloses a preparation method of a chicken feed additive, wherein the raw materials of the chicken feed additive are as follows: 10 to 30 parts of chitosan, 10 to 30 parts of xylo-oligosaccharide, 3 to 6 parts of indigowoad leaf extract, 8 to 10 parts of dandelion extract and 8 to 10 parts of liquorice extract; the preparation method comprises the following steps of: extracting thedandelion extract, the liquorice extract and the indigowoad leaf extract respectively, and then mixing the extracts with the xylo-oligosaccharide uniformly to obtain the chicken feed additive. The chicken feed additive disclosed by the invention can be used for efficiently increasing the laying rate of hens and enhancing the immunity of the chicken; antibiotics are not needed, so that the production of green pollution-free eggs is facilitated.

Description

technical field [0001] The invention relates to a preparation method of a natural green chicken feed additive. Background technique [0002] At present, in order to reduce various diseases of chickens, antibiotics such as chlortetracycline, oxytetracycline, etc. are added during the breeding process. Some breeding companies often add excessive antibiotics, causing antibiotic abuse through the food chain, and causing harm to human health. Therefore, replacing antibiotics with safe natural active ingredients has become the key to the production of green poultry and egg food. Some data show that some natural polysaccharides (such as chitosan, astragalus polysaccharide, wolfberry polysaccharide, etc.) Intestinal and respiratory diseases. Therefore, the appropriate compatibility of polysaccharides, oligosaccharides and traditional Chinese medicine extracts to replace antibiotics has a good development prospect. Contents of the invention [0003] The purpose of the present in...
