Abstract

The invention discloses an anti-porcine circovirus disease composition, a mixed freeze-dried powder and a preparation method. The composition comprises the following components in parts by weight: 94-97 parts of anti-porcine circovirus disease yolk antibody, anti-porcine circovirus disease 1-2 parts of porcine circovirus disease transfer factor; the mixed freeze-dried powder also includes 0.01-0.02 parts of preservatives, 0.2-0.3 parts of inactivators, 0.05-0.1 parts of selenium, 0.5-1 parts of vitamin C, polyvinylpyrrolidone 1 to 2 parts, 0.5 to 1 part of glycine. The anti-porcine circovirus disease mixed freeze-dried powder of the present invention is compounded by anti-porcine circovirus disease egg yolk antibody and anti-porcine circovirus disease transfer factor, and supplemented with various auxiliary materials, and the components cooperate with each other. The coordination effect can significantly improve the effect of preventing and treating porcine circovirus disease. It has the advantages of strong pertinence, long storage time at room temperature, high antibody titer, and good biological activity. It is a powerful biological agent with broad application prospects. .

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine, and in particular relates to a composition for resisting porcine circovirus disease, and also relates to a mixed freeze-dried powder for resisting porcine circovirus disease and a preparation method of the mixed freeze-dried powder. Background technique [0002] Pig breeding occupies a relatively large share in my country's breeding industry. In 2009, Henan Province alone produced 4.1032 million tons of pork. It can be seen that my country's annual demand for pork is very large. However, with the increasing demand for pork and the expansion of breeding scale, more and more problems have appeared in the pig breeding process, among which porcine circovirus disease is an acute infectious disease, which has caused huge damage to the pig industry. Economic losses. [0003] Porcine circovirus (PCV) is the smallest animal virus ever discovered. It is known that PCV has two serotypes, namel...
