Problems solved by technology

[0003] At present, there are only products such as human placental lipopolysaccharide and sheep placenta (sheep placental lipopolysaccharide) on the market, and the current scope of use is limited to human medicines and cosmetics. The above-mentioned human placental lipopolysaccharide and sheep placenta are relatively expensive, and placenta is used in animal medicines Lipopolysaccharide is still blank, and it is not suitable to be used in animals such as livestock and poultry
The use, sales and reports of pig placenta have not been found

Embodiment Construction

[0015] The pig placenta of the invention is composed of pig placenta and trypsin, and the proportion is 1 kg of pig placenta plus 1000-2000 U of trypsin. Among them, the pig placenta can provide polysaccharides, nucleic acids, proteins, and trypsin is used for enzymolysis.

[0016] The preparation technology step of this pig placenta is as follows:

[0017] A. Pretreatment: remove the umbilical cord, blood and fat from the pig placenta that has passed the quarantine, cut it into pieces, and steam sterilize it at 121°C for 30 minutes;

[0018] B. Hydrolysis: Take the pretreated pig placenta, add 10 times the amount of water, add sodium hydroxide or sodium carbonate to adjust the pH to 7.0-9.0, and heat to 45-65°C;

[0019] C. Digestion: add trypsin according to the ratio of 1 kg of pig placenta plus trypsin 1000-2000U, and digest for 2 hours. On this basis, add 1-10% by weight of chloroform or a mixture of chloroform and n-butanol in a weight ratio of 5:2;

[0020] D. Deprot...

Abstract

The invention relates to a placenta extract, in particular to a process for preparing a pig placenta extract. The preparation process comprises the following steps of: A, pre-processing; B, hydrolyzing; C, digesting; D, performing deproteinization; E, performing alcohol deposition and purification; F, sub-packaging and sterilizing; and G, preparing the preparation. In the invention, the placenta extract (the pig placenta lipopolysaccharide) extracted from the pig placenta is prepared into injection and oral solution so as to enhance the immunity of animals, improve the disease resistance of the animals, reduce or avoid an antibiotic medicament, and ensure the safety of an animal product. The product is a non-specific preparation which can enhance the non-specific immunity of the animals to a plurality of bacteria and viruses; the product has no medicament residue after being used; the product is convenient to use and is unnecessary to store at a low temperature; besides injection, theproduct has good oral effect; and the product also has the advantages of broad source of main raw materials, low cost and readily available materials.

Description

technical field [0001] The invention relates to a placenta, in particular to a preparation process of a pig placenta. Background technique [0002] At present, the treatment of animal husbandry is more important than the prevention of the status quo, leading to the abuse of antibiotics, causing endogenous infections and multiple infections in animals, the emergence of drug-resistant strains, and drug residues in animal products, which seriously hinder the healthy development of animal husbandry, especially last year. The occurrence of the incident has once again sounded the alarm for people on food safety issues. With the gradual popularization of the concept of healthy pig raising, the development of animal health products has attracted more and more attention. With the complete prohibition of antiviral western medicine in the field of veterinary medicine, the development of drugs to enhance animal immunity is becoming more and more important. [0003] At present, there ar...
