  • Method of quickly producing antibodies against avian influenza and maintain antibody titer of duck
    Patent number: 10124057
    Abstract: The present invention provides a method for enabling ducklings to quickly produce anti-avian influenza antibodies and maintain antibody titer, including: step 1) the first immunization is performed on ducklings at the age of 5 to 15 days: each duckling is inoculated with an avian influenza inactivated antigen in an abdomen, and simultaneously intramuscularly or subcutaneously immunized with an avian influenza inactivated oil-emulsion vaccine. In the method, through the double effects of intraperitoneal inoculation with the inactivated antigen and intramuscular or subcutaneous injection with the inactivated oil-emulsion vaccine on the ducklings, the ducklings can quickly produce an immune response so as to quickly produce the anti-avian influenza antibodies; and the immune dead time of the ducklings immunized with the avian influenza inactivated vaccine can be effectively reduced by more than 7 days.
