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, antiviral freeze-dried powder for a feed additive and a preparation method and use of the antiviral freeze-dried powder, and belongs to the technical field of veterinary feed additives. The antiviral composition comprises, by weight, 90-100 parts of an antiviral yolk antibody and 1-2 parts of an antiviral transfer factor. The freeze-dried powder comprises, by weight, 95-97 parts of the antiviral yolk antibody, 1-2 parts of the antiviral transfer factor, 0.2-0.3 parts of an inactivator, 0.01-0.02 parts of an antiseptic and 2.05-3.6 parts of a heat-resistant freeze-dried protective agent. The freeze-dried powder has the advantages of low preservation conditions, long preservation time, high antibody titer and good biological activity. Through combined use of the antiviral transfer factor and the antiviral yolk antibody, the freeze-dried powder has effects of preventing and treating virosis, improves immunity and a survival rate of livestock and poultry, is convenient for use and has a 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...
