Abstract

The invention discloses a mixed freeze-dried powder for resisting swine viral diseases and a preparation method thereof. The mixed freeze-dried powder comprises the following components in parts by weight: 90-95 parts of anti-swine virus disease yolk antibody, anti-swine virus disease 1-2 parts of transfer factor, 1-2 parts of α-interferon, 1-2 parts of antioxidant, 0.01-0.02 part of preservative, 0.2-0.3 part of inactivator, 0.05-0.1 part of selenium, 1-2 parts of polyvinylpyrrolidone 0.5-1 part of glycine, 0.5-1 part of active lactobacillus. The anti-porcine viral disease mixed freeze-dried powder of the present invention is compounded with anti-porcine viral disease egg yolk antibody, anti-porcine viral disease transfer factor and immune enhancer, supplemented with various auxiliary materials, and each component cooperates and coordinates It can significantly improve the effect of preventing and treating porcine viral diseases, and has the advantages of strong pertinence, long storage time at room temperature, high antibody titer, and good biological activity.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicines, and in particular relates to a mixed freeze-dried powder for resisting porcine viral diseases, and also relates to a preparation method of the mixed freeze-dried powder for resisting swine viral diseases. Background technique [0002] Porcine viral disease is a general term for different degrees of acute and highly contagious diseases caused by different viruses, including swine fever, porcine ring disease, porcine pseudorabies, porcine parvovirus disease and other diseases. Porcine viral disease is the most common disease in the pig industry. Because of its sudden onset, short course of disease, and high mortality, it is still one of the main hazards in the pig industry. [0003] There are many ways to prevent and treat porcine viral diseases at present, mainly using western medicine, vaccination, Chinese herbal medicine, etc. to prevent and treat. Among them, the widespread use of...
