Problems solved by technology

[0002] Pig is an important livestock product. As a food production resource, it plays a very important role in people's life. However, the morbidity and mortality of pigs are very high in my country, especially in southern provinces, where the mortality rate of pigs reaches 8~ 12%, most of which are caused by diarrheal diseases, and diarrheal diseases are mainly caused by Escherichia coli, infectious gastroenteritis, epidemic diarrhea and rotavirus, which seriously endanger the development of animal husbandry. However, for Porcine diarrhea disease, we still stay at

Embodiment Construction

[0013] Example 1 of the present invention provides an anti-swine diarrhea egg yolk antibody feed additive, which is prepared by immunizing non-immune laying hens with a single vaccine prepared by porcine E. The preparation method of antibody feed additive is:

[0014] 1. Isolate porcine E. coli for proliferation and culture, and prepare a porcine E. coli single vaccine when it has antigenicity;

[0015] 2. Use the prepared porcine Escherichia coli single vaccine to immunize non-immune laying hens. During the first immunization injection, each chicken is injected with 1ml of anti-porcine Escherichia coli single vaccine prepared intramuscularly or subcutaneously, and then two weeks later with the first immunization. Doubling the dose of the first immunization for the second immunization, two weeks later the third immunization with four times the dose of the first immunization, and then every other month with twice the dose of the first immunization for a second immunization to i...
