Embodiment Construction

[0026] Prepare the chicken feed additive according to the following raw material formula and preparation method:

[0027] The raw material components and weight proportions of the chicken feed additive are: 20 parts of chitosan, 20 parts of isomalto-oligosaccharide, 5 parts of Hypericum perforatum extract, 8 parts of dandelion extract and 8 parts of licorice extract. The average molecular weight of chitosan is between 1000 and 50000.

[0028] The steps of the preparation method are:

[0029] a. Preparation of dandelion extract: crush whole dandelion into 50-mesh granules, heat and extract with 70 volume % ethanol of 10 times the weight for 3 hours, concentrate under reduced pressure to 1 / 5 of the initial liquid volume, and spray dry to obtain the extract Particles were extracted three times in the same way.

[0030] 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 under reduc...

Abstract

The invention discloses a preparation method of a chicken feed additive containing chitosan. The chicken feed additive comprises the following raw materials: 15-30 parts of chitosan, 10-30 parts of isomaltose hypgather, 3-6 parts of a hyperforin perforatum extract, 8-10 parts of a dandelion extract and 8-10 parts of a licorice extract. The preparation method comprises the following steps: extracting the dandelion extract, the licorice extract and the hyperforin perforatum extract respectively, and then uniformly mixing the dandelion extract, the licorice extract and the hyperforin perforatum extract with chitosan and isomaltose hypgather so as to obtain the chicken feed additive containing chitosan. The chicken feed additive can be effectively used for improving the egg laying rate, and strengthening the immunity of chicken without adding antibiotics, and is beneficial to laying environment-friendly eggs.

Description

technical field [0001] The invention relates to a preparation method of a chicken feed additive containing chitosan. 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 pres...
