How to prevent epidemic in Gosling flocks

Gosling plague live vaccine immunization: goslings who were not immunized with Gosling plague live vaccine, or goslings who were immunized with Gosling plague live vaccine 100 days later, were immunized with Gosling plague live vaccine subcutaneously within 2 days after hatching.

It is necessary to raise in isolation within 7 days after immunization to prevent the disease caused by virulent infection in the field before immunity is produced. 7 days later, the immunized goslings have developed immunity and can basically resist virulent infection without disease.

The goslings of the offspring of immunized breeder geese have maternal antibodies and do not need to be immunized with live vaccine, because the maternal antibody can neutralize the virus in the live vaccine, so that the live vaccine can not produce enough immunity.

Gosling plague antiserum immunity: in areas where there was no Gosling plague epidemic, susceptible goslings were injected subcutaneously with 0.5 ml per Gosling at the age of 7 days.

Goose hemorrhagic necrotizing hepatitis inactivated vaccine immunization: goslings about 10 days old with inactivated vaccine immunization, each feather subcutaneous injection of 0.5 ml.

Goose serositis inactivated vaccine immunization: goslings were immunized with inactivated vaccine at the age of 7-15 days, with 0.5 ml subcutaneous injection per feather.

Vaccination against avian influenza inactivated vaccine in geese: goslings whose offspring have not been immunized or those who have been immunized for 3 months for the last time should first be immunized with avian influenza. If there is no such epidemic in the local area, they can be immunized with oil emulsion inactivated vaccine at the age of 10 mi 15 days, with 0.5 ml per feather subcutaneously injected; if there is an epidemic in the area, inactivated vaccine should be selected at the age of 5-7 days, with 0.5 ml per feather injected.
