[Method] A total of 180 Sanhuang chickens were selected from a breeding chicken farm in Guilin City of Guangxi and assigned into four groups （ n = 45）. At 145 days old, the chickens in the group I and II were respectively inoculated with AIV Re-5 strain and AIV SS strain, but they were kept in cages separately. The two control groups were not inoculated. Antibody levels were determined at 170 days old. [ Result] The level of antibodies against AIV Re-5 strain was significantly higher in the chickens of the group I and group II than in the corresponding control groups, respectively （ P 〈 0.01 ）. The level of antibodies against AIV SS strain was not significantly different between the group I and its control group or between the group II and its control group. [ Conclusion] The antibody level of chickens can be increased by the AIV Re-5 strain but not by the AIV SS strain.展开更多
