摘要
用鸽 A/ P M V1 油佐剂灭活苗与 N D V 油佐剂灭活苗分别免疫雏鸡,免疫后21 d 抗体水平达到峰值,免疫后42 d 用新城疫强毒对两种疫苗免疫鸡分别进行攻击,鸽 A/ P M V1 油佐剂灭活苗免疫组保护率为73.33% , N D V 油佐剂灭活苗免疫组保护率为99.67% 。
Two groups of chickens were vaccinated with oil emulsion inactivated vaccine made from pigeon PMV 1 SX strain and Newcastle disease virus (NDV) LaSota strain respectively .The antibodies titer reached peak at 21 d post immunization .the challenge tests using NDV virulent strain acted at 42 d post immunization,the protective rate (PR) of pigeon PMV 1 vaccine which resisted NDV was 77.3%, but the group vaccinated with NDV vaccine attained 99.69% PR.
