Abstract
Studies were carried out to evaluate the development of immune response and build up of protective hemagglutination inhibition (HI) titers in commercial Japanese quails following subcutaneous (s/c) vaccination with inactivated oil-emulsion avian influenza virus(AIV) (H5N2 or H5N1) vaccines from different origin.These studies revealed the following results: 1- Quails vaccinated s/c at 14 days of age, with 0.3 ml/bird revealed relatively high post-vaccination response as compared to quails vaccinated at 7 days of age with the same dose. 2- When commercial Japanese quails were vaccinated with inactivated oil emulsion H5N1 or H5N2 AIV vaccines: either one time at 7 days of age with 0.3 ml/bird or two times at 7&28 days of age, with 0.3 and 0.5 ml/bird of these vaccines, respectively, the immune response values were more satisfactory after the second vaccination.3- When commercial Japanese quails were vaccinated with inactivated oil emulsion H5N1 or H5N2 AIV vaccines: either one time at 14 days of age or two times at 14&35 days of age, with 0.3 and 0.5 ml/bird of these vaccines, respectively, the immune response values were more satisfactory after the second
vaccination. 4- There is a slight difference between the obtained HI titers for the two commercial inactivated oil emulsions H5N1 or H5N2 AIV vaccines used in this study.
