Problems solved by technology

However, these traditional feed additives are deficient and have produced many negative effects. Common cancers, deformities, drug resistance and certain poisoning phenomena in humans are related to the residues of antibiotics, hormones and other synthetic drugs in meat, milk and eggs. The use of these additives will also reduce the flavor and quality of livestock products

Embodiment 1

[0012] Embodiment 1, (1) Chitosan is put into hydrochloric acid solution, stirs, obtains liquid chitosan solution; Acid concentration 0.5% (2) Chitosan solution is warming up to 45 ℃, adjusts pH value and reaches 5.0, adds The composite enzyme is stirred, and the composite enzyme is composed of protease, elastase, amylase, lipase and lysozyme, and its weight percentage is 30%: 20%: 10%: 20%: 20%. The weight ratio of compound enzyme to chitosan oligosaccharide is 5%. Enzymolysis for 2 hours to obtain an enzymolysis solution; (3) filtering the enzymolysis solution to remove impurities such as enzyme protein to obtain an enzymolysis clear solution; (4) sending the enzymolysis clear solution into a concentrator for concentration to obtain concentrated solution; (5) pouring the concentrated solution into a spray dryer for spray drying to obtain solid chitosan oligosaccharide; (6) grinding and mixing the solid chitosan oligosaccharide with Chinese medicinal materials to obtain an ad...

Embodiment 2

[0013] Embodiment 2, (1) chitosan is put into lactic acid solution, stirs, obtains liquid chitosan solution; Acid concentration 0.5% (2) chitosan solution is warming up to 45 ℃, adjusts pH value and reaches 5.0, adds The composite enzyme is stirred, and the composite enzyme is composed of protease, elastase, amylase, lipase and lysozyme, and its weight percentage is 30%: 20%: 10%: 20%: 20%.

Embodiment 3

[0014] Embodiment 3. The feed additive was added to the feed of suckling pigs at a ratio of 0.1%. The average weight of the suckling pigs was 1.2 kg, and they were fed continuously for two months. The weight of the blank group was 21.2 kg, and that of the control group was 24.3 kg, an average increase of 14.6% compared with the blank group. Pigs fed with this feed additive have strong appetite, smooth fur and strong muscles.

Abstract

The present invention is feed additive containing chitin oligose and its preparation and use. Chitin oligose is prepared with chitosan and through dissolving in acid solution to obtain chitosan solution; heating chitosan solution at 30-60 deg.c, regulating pH value to 5-6, adding composite enzyme for enzymolysis of 2-5 hr to obtain enzymolyzed liquid; filtering to eliminate zymoprotein and other impurity to obtain clear enzymolyzed liquid; concentrating the enzymolyzed liquid to obtain concentrated liquid; spray drying to obtain solid chitin oligose. The obtained solid chitin oligose is mixed with Chinese medicinal materials and crushed to obtain the additive. The additive has bacteriostasis function, no toxic side effect, no residue of harmful matter and no drug resistance, and may be used in various feeds for farm animal and aquatic animal to raise feed utilization, raise product quality and strengthen immunity.

Description

technical field [0001] The invention relates to a feed additive containing chitosan oligosaccharide and its preparation method and application. More specifically, the invention relates to the composition of chitosan oligosaccharide and Chinese medicinal materials, its preparation method and application. Background technique [0002] At the beginning of the 20th century, people began to engage in the research of feed additives. Traditional feed additives are various amino acids, antibiotics, new synthetic drugs and hormones, etc. These feed additives have comprehensively promoted the development of the feed industry, aquaculture, and animal husbandry, and formed a specialized industry. However, these traditional feed additives are deficient and have produced many negative effects. Common cancers, deformities, drug resistance and certain poisoning phenomena in humans are related to the residues of antibiotics, hormones and other synthetic dr...
