The present invention is applicable to the field of biotechnology, and provides a method for preparing duck reovirus refined egg yolk antibody, comprising the following steps: step S1, producing and selecting virus seeds according to virus seed standards; step S2, diluting the virus seeds Inoculate and extract the antigen after inspection; according to the instructions for use, the prevention and protection rate of duck "hepatosplenic necrosis" is 99.79%; it is used for the early, middle and late treatment of duck "hepatosplenic necrosis", which is comparable to conventional treatment Compared with the methods, the survival rate has been increased by 7.28%, 5.82% and 2.21% respectively, and the refined yolk antibody of duck reovirus prepared by the present invention provides clinical prevention and treatment of duck "liver and spleen necrosis" caused by duck reovirus. Effective means, compared with conventional treatment methods, the duck reovirus refined yolk antibody prepared by the invention can significantly reduce the economic loss caused by the disease to the meat duck breeding industry, and has significant economic and social benefits. |
