A polypeptide composition, a composition for improving the immune function of livestock and poultry, and a preparation method

Abstract

The invention relates to the technical field of livestock breeding, and in particular, discloses a polypeptide composition, a composition for improving the livestock and poultry immune function, and a preparation method of the composition for improving the livestock and poultry immune function. The polypeptide composition is prepared from bursin peptide, thymosin and a transfer factor according to the mass ratio of (0.5-5):(0.5-5):(0.5-5). The composition for improving the livestock and poultry immune function is prepared from the following raw materials in parts by weight: 20-30 parts of B vitamins, 20-30 parts of vitamin C, 10-20 parts of the polypeptide composition, 10-15 parts of taurine, 1-2 parts of an anti-caking agent, and 40-50 parts of porous starch. The polypeptide composition and the composition can both be used as feed additives, or as pharmaceutical preparations to be added in drinking water, or as pharmaceutical preparations used for injection, have good prevention and control effects on swine fever, foot-and-mouth disease, circovirus, piglet diarrhea, Newcastle disease, mild type flu, duck liver virus disease and the like, reduce the use of antibiotics, reduce the occurrence of epidemic diseases, reduce mortality rate, and improve the immunity.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a polypeptide composition, a composition for improving the immune function of livestock and poultry, and a preparation method. Background technique [0002] Viral diseases are currently the most troublesome diseases in the livestock and poultry breeding industry. In the traditional breeding process, in order to resist viral diseases, a large number of antibiotics and large doses of vaccines are usually used, coupled with improper and closed breeding conditions, dirty breeding The environment can cause viruses and bacteria to breed, mutate, and produce drug resistance, resulting in overload of the immune system, immune cell damage or immune paralysis, immunosuppressive diseases, such as chronic swine fever virus, porcine blue ear virus, porcine circovirus Immunosuppressive diseases caused by piglet diarrhea virus, avian Newcastle disease virus, and avian mild influenza vi...

AI Technical Summary

Problems solved by technology

In addition, during the long-term breeding and rapid growth of animals, the virus quickly accumulates toxins in the animal body or blood, causing burden or damage to the liver and kidneys

Moreover, with the abuse of a large number of antibiotics and antiviral chemical drugs in the current stage of breeding, the continuous mutation of viruses and bacteria and the emergence of drug resistance make the treatment and prevention and control effects worse and worse, and the casualty rate of farmed animals is getting higher and higher. , it is difficult to control the cost and risk of breeding, and it will also cause drug residues in the meat. Therefore, in order to improve food safety, the abuse of antibiotics is no longer allowed in the process of raising animals, and antiviral drugs are banned and used, such as King Kong Alkylamine, ribavirin, morpholinoguanidine, etc.
