Problems solved by technology

[0005] At present, people use vaccines to immunize canine distemper, and the early effect is better, but multiple vaccinations are required, the operation is troublesome, the cost is high, and it is easy to cause stress reactions in livestock and poultry, and the vaccines have strict requirements for storage conditions. Refrigerate at low temperature, and it will fail after a period of time at room temperature

Abstract

The invention discloses an antiviral composition for a feed additive, a freeze-dried powder, a preparation method and an application, and belongs to the technical field of animal feed additives. The composition is composed of the following components in parts by weight: 90-100 parts of antiviral yolk antibody and 1-2 parts of antiviral transfer factor. The freeze-dried powder is composed of the following components in parts by weight: 95-97 parts of antiviral egg yolk antibody, 1-2 parts of anti-viral transfer factor, 0.2-0.3 part of inactivator, 0.01-0.02 part of preservative, heat-resistant freeze-dried 2.05-3.6 parts of protective agent; it has the advantages of reducing storage conditions, prolonging storage time, high antibody titer, and good biological activity. The combined use of anti-viral transfer factor and anti-viral yolk antibody has the effect of preventing and treating viral diseases, and can improve the quality of livestock and poultry. Immunity and survival rate, easy to use and low cost.

Description

technical field [0001] The invention specifically relates to an antiviral composition for a feed additive, and also relates to an antiviral freeze-dried powder, a preparation method and application of the freeze-dried powder, and belongs to the technical field of animal feed additives. Background technique [0002] Viruses are composed of nucleic acid and protein capsids, which are simple in structure and cannot survive independently. When the virus invades the body, if it is not cleared in time, it will infect the normal cells of the body, proliferate and spread, and cause harm to the health of the body, especially to the livestock breeding industry. At present, the treatment of viral diseases in livestock and poultry mainly takes antibiotics or vaccinations. However, antibiotics can easily cause the body to develop drug resistance, and the method of vaccination is relatively complicated, and the success rate is not high. [0003] Dog breeding has developed rapidly in our...
