Effectiveness of an inactivated goose parvovirus vaccine in Muscovy ducks.
With goose parvovirus (GPV) strain IH, an inactivated vaccine was prepared from allantoic fluid of embryonating Muscovy duck eggs inoculated with GPV. The response to vaccination was measured by virus neutralizing antibody titer against GPV. Offsprings from the vaccinated flock were introduced in a farm in which GPV infection had been experienced and examined for resistance to exposure to GPV. The results showed that the intramuscular vaccination to Muscovy ducks at any age stimulated significant virus neutralizing antibody levels, and that more than 90% Muscovy ducklings from the vaccinated parent flock survived after the exposure to GPV. Muscovy ducklings that passively possessed high level virus neutralizing antibodies also could respond to the vaccination and the induced antibodies remained for more than 2 months.
