A kind of veterinary antiviral composition, freeze-dried powder, preparation method and application

Abstract

The invention discloses a veterinary antivirus composition, freeze-dried powder, a preparation method and applications of the composition, and belongs to the technical field of veterinary feed additive. The veterinary antivirus composition is mainly composed of the following components in parts by weight: 85 to 100 parts of veterinary antivirus yolk antibody, 1 to 5 parts of veterinary antivirus transfer factor, and 1 to 5 parts of alpha-interferon; and preferably also comprises the following components in parts by weight: 5 to 10 parts of astragalus polysaccharide, 5 to 10 parts of angelica polysaccharide, 10 to 20 parts of wolfberry polysaccharide, and 10 to 30 parts of licorice polysaccharide. The veterinary antivirus yolk antibody, veterinary antivirus transfer factor, alpha-interferon, astragalus polysaccharide, angelica polysaccharide, wolfberry polysaccharide, and licorice polysaccharide are co-used, and thus the composition has the advantages of strong pertinency, high antibody titer, and good bio-activity, is capable of improving the organism immunity and disease preventing ability, and effectively prevents the animal viral diseases.

Description

technical field [0001] The invention specifically relates to a veterinary antiviral composition, and also relates to a veterinary 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] The pig industry occupies a relatively heavy share in my country's aquaculture industry, but with the increasing demand for pork, more and more problems appear in the pig raising process, including swine fever, porcine parvovirus disease, porcine pseudorabies, pig blue Viral diseases such as ear disease have caused huge economic losses to the pig industry. [0003] At present, people mainly prevent and treat viral diseases through methods such as traditional Chinese medicine, western medicine, and vaccination. Among them, Chinese medicine is one of the main research directions, but there are many types of Chinese medicine, and the effects of the same medicinal mat...

AI Technical Summary

Problems solved by technology

Among them, traditional Chinese medicine is one of the main research directions, but there are many types of traditional Chinese medicine, and the effects of the same medicinal material on different poultry diseases vary greatly, so there are certain limitations

However, western medicines such as antibiotics tend to produce drug residues, which bring great safety hazards to meat products, and antibiotics are prone to produce resistant strains after long-term use

The early effect of biological treatment such as vaccination is better, but multiple vaccinations are required, the operation is troublesome, the cost is high, and it is easy to cause stress reaction in piglets, and the vaccine has high requirements for storage conditions, which need to be refrigerated at 2-8 °C , it loses its effect at room temperature for a period of time

Injection of egg yolk antibody is also a relatively common method, but the immune effect of a single injection of egg yolk antibody sometimes cannot meet the actual needs
