Abstract

The invention is applicable to the technical field of biology, and provides a preparation method of a refined egg yolk antibody for duck reovirus. The method comprises the following steps: S1, producing and selecting a virus variety according to the virus variety standard; S2, diluting the virus variety and then inoculating, testing and then extracting the antigen; according to the instructions for use, the refined egg yolk antibody has a prevention and protection rate of 99.79% when being used for'spleen and spleen necrosis' of ducks; when the refined egg yolk antibody is used for early, middle and late treatment of the'spleen and spleen necrosis' of the ducks, the survival rates are respectively increased by 7.28%, 5.82% and 2.21% compared with conventional treatment method. The refinedegg yolk antibody, prepared by the method, for the duck reovirus provides an effective means for the clinical prevention and treatment of the 'spleen and spleen necrosis', caused by the duck reovirus,of the ducks; compared with the conventional treatment method, the refined egg yolk antibody for the duck reovirus can remarkably reduce the economic loss brought to the duck breeding industry, thushaving significant economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a method for preparing duck reovirus refined yolk antibody. Background technique [0002] Since March 2017, a kind of duckling has been popular in the farms of large-scale meat duck breeding groups in China. The clinical symptoms are soft feet, loose stools, and the pathological changes are yellowish necrosis in the liver and occasional bleeding points, and gray-white necrosis in the spleen. Or spleen enlargement and purple-black disease, which is clinically called duck "liver and spleen necrosis", and the causative pathogen is duck reovirus. All kinds of ducks, such as shelduck, white-feathered meat duck, hybrid duck, etc., are prone to occurrence, but cherry valley duck is more prone to occurrence. The age of onset is mostly within 9 days, the incidence rate is less than 30%, and the mortality rate within 7 days after onset is 10%. about [0003] Currently, there is no clinical a...
