摘　　要：禽流感和新城疫是严重危害养禽业发展的疫病,为了解平阳地区某粉壳蛋鸡养殖场禽流感和新城疫免疫效果及禽流感H7亚型病毒感染状况,于2018—2020年每3个月对该规模蛋鸡场进行采样,共采集10个批次的血清样品和鸡喉肛棉拭子样品各329份,并进行血清学和病原学检测。结果显示:禽流感H5亚型10个批次免疫抗体合格率在83%以上,禽流感H7亚型9个批次免疫抗体合格率在83%以上,仅1个批次的合格率低于70%,新城疫10个批次免疫抗体合格率在94%以上;禽流感H7亚型病原学检测结果均为阴性。说明该养殖场禽流感和新城疫的免疫效果良好,无禽流感H7亚型病毒感染的情况。In order to explore the immune effect of avian influenza and newcastle disease and investigate the infection status of avian influenza virus subtype H7 from a pink-shell egg farm in Pingyang area.All the samples of 10 batches were collected on the farm every three months from 2018 to 2020,in which 329 samples were obtained from serum specimens and 329 samples were from larynx and anal swabs.The results showed that the immune antibody qualification rates of avian influenza virus subtype H5 and subtype H7 were both over 83%,only one immune antibody qualification rate of avian influenza virus subtype H7 of one batch lower than 70%.The immune antibody qualification rates of newcastle disease of 10 batches were all above 94%.The results of pathogen detection of avian influenza virus subtype H7 were all negative.It was concluded that satisfactory immune effect on avian influenza and newcastle disease,and no infection of avian influenza virus subtype H7 in the farm.
