Abstract: An inactivated astragalus polysaccharide (APS) adjuvant vaccine was developed with Riemerella anatipestifer (RA) serotype Ⅰ isolated from Wuhan in this research. Ducks were inoculated with optimal dosage (0.3 mL/duck) at the age of 5-day. The protection rates were 100%, 90%, 100%, 100% and 90% on the 3 rd, 7 th, 10 th, 14 th and 21 st day after vaccination, respectively. Immunodiffusion assay showed that the specific antibody could be found since 3 rd day post inoculation, and reached peak on 10 th day (P<0.01). These results suggested that this vaccine could against duck infectious serositis effectually.
