How to carry out epidemic prevention work for gosling flocks during goose raising
Immunization with live gosling plague vaccine for goslings: For goslings from breeding geese that have not been immunized with live gosling plague vaccine, or goslings from breeding geese 100 days after immunization with live gosling plague vaccine, administer subcutaneous injection immunization with live gosling plague vaccine for goslings within 1-2 days after hatching.
Within 7 days after immunization, isolated rearing is required to prevent disease caused by infection with virulent field virus before immunity develops. After 7 days, immunized goslings have developed immunity and can basically resist infection with virulent virus without becoming ill.
The offspring of immunized breeding geese have maternal antibodies during the effective period, so live vaccine immunization is not needed, because maternal antibodies can neutralize the virus in the live vaccine, preventing the live vaccine from producing sufficient immunity and resulting in immunization failure.
Immunization with gosling plague antiserum: In areas where gosling plague is not prevalent, susceptible goslings at 1-7 days of age are given a subcutaneous injection of 0.5 milliliters per gosling.
Immunization with inactivated vaccine for goose hemorrhagic necrotizing hepatitis: Goslings around 10 days of age are immunized with inactivated vaccine, with a subcutaneous injection of 0.5 milliliters per bird.
Immunization with inactivated vaccine for goose serositis: Goslings at 7-15 days of age are immunized with inactivated vaccine, with a subcutaneous injection of 0.5 milliliters per bird.
Immunization with inactivated vaccine for goose avian influenza: For goslings from breeding geese whose offspring have not been immunized, or goslings from breeding geese 3 months after the last immunization, avian influenza immunization should be carried out first. If there is no outbreak of this disease locally, oil-emulsion inactivated vaccine can be used at 10-15 days of age, with a subcutaneous injection of 0.5 milliliters per bird; if there is an outbreak locally, inactivated vaccine should be used at 5-7 days of age, with an injection of 0.5 milliliters per bird.
