Abstract

Research background: H5 and H7 highly pathogenic avian influenza (HPAI) outbreaks have caused huge economic losses among poultry farms which has prompted the Ministry of Agriculture and Rural Affairs of China to make immunization mandatory for both the H7 HPAI virus and H5 HPAI virus. Research methods: To determine the effects of immunization, 8,916 serum samples were collected from 294 flocks between 2019 and 2021 and subjected to serum antibody testing using the hemagglutination inhibition (HI) test. Our results showed that immune antibodies against H5 and H7 HPAI viruses exceeded 70% during the 3-year period, with layer farms and the eastern region having the most effective immunization. Greater focus on immune antibody monitoring is required in the southern, northwestern, and midland regions. Additionally, the immunization density and antibody monitoring efforts of broiler chicken farms should be further strengthened to enhance the overall prevention and control of major animal epidemic diseases.
