Problems solved by technology

Potassium chloride, potassium sulfate, etc. are currently added to the feed. These inorganic potassium salts are deficient, such as bitter taste, which affects palatability; chloride ions, sulfate ions, etc. affect the acid-base balance, which can cause diarrhea in farmed animals and feed stool. And other phenomena, trouble farmers

Embodiment 1

[0041] An animal anti-stress feed additive, said additive comprises: chitosan oligosaccharide potassium, glucose oxidase, silicon dioxide, and the composition content of its additive is:

[0042] Potassium chitosan oligosaccharide 60 parts

[0043] Glucose oxidase 15 parts

[0044] Silica 5 parts

[0045]The potassium chitosan is obtained by an enzyme reaction; the specific steps of the enzyme reaction are: adding cellulase and glucose oxidase ( Add cellulase and glucose oxidase at one time, the mass ratio of the total amount of cellulase added to chitosan is 1:150, the mass ratio of the total amount of glucose oxidase added to chitosan oligosaccharide is 1:150), flow Add 15% dipotassium hydrogen phosphate solution (the solvent is water), the flow rate is 2 liters / min, and the feeding time is 2 hours to maintain the pH of the solution at 5.0-7.0 and maintain the temperature at 55±0.5°C. The ventilation volume is 1vvm, the tank pressure is maintained at 0.2-0.5MPa, the stirr...

Abstract

The invention discloses an anti-stress feed additive based on a purification chelation process, and a preparation method and application thereof. According to animal physiology, nutrition regulation and other theories, the feed additive comprises potassium chitosan oligosaccharide, glucose oxidase and silicon dioxide. The animal anti-stress additive provided by the invention does not contain any antibiotics, antiviral preparations and growth hormones, and can regulate electrolyte and acidolysis balance in animal bodies, enhance superoxide dismutase activity, relieve various stresses and achieve the purpose of animal anti-stress. The feed additive is a safe and efficient novel green feed additive, and can be added to bred animals in various growth stages for a long time.

Description

technical field [0001] The invention belongs to the technical field of chelation (complexation) feed additive production, and specifically relates to a high-purity shell oligopotassium anti-stress feed additive based on chelation (complexation) technology and its preparation method and application. Background technique [0002] Oligochitosan refers to oligosaccharides linked by D-glucosamine with β-1.4 glycosidic bonds. It is obtained by enzymatic hydrolysis of chitosan. Studies have found that adding chitosan to diet can promote the growth of animals and improve the intestinal environment of the body. , Inhibit the growth of harmful bacteria and affect the formation of intestinal flora. In addition, chitosan can enhance the function of some organs of the body, increase the activity of some enzymes in the body, the activities of total superoxide dismutase (T-SOD), peroxidase (POD) and lysozyme (LSZ), and inhibit certain secretion of harmful substances. [0003] Potassium i...
