Surveillance and Analysis of Immune Antibodies Against Swine Fever and Footandmouth Disease in Huishui County, Guizhou Province in 2022

Abstract:

This study aims to understand the immune antibodies of swine fever (CSF) and footandmouth disease (FMD) in Huishui County, predict their epidemic trends and assess their occurrence risks. This experiment used the ELISA detection method to detect a total of 2,099 CSF samples from pig farms (households) in Huishui County in 2022, and 1,797 swine footandmouth disease type O (FMDO) samples. Results: (1) The overall qualified rate of CSF immune antibodies was 90.14%, the qualified rate of largescale pig farms was 93.11%, the qualified rate of freerange households was 84.60%, the qualified rate of largescale pig farms was 97.87%, and the qualified rate of freerange households was 75.26 %; (2) The overall pass rate of FMDO immune antibodies is 91.96%, the pass rate of largescale pig farms is 96.72%, the pass rate of freerange pig farms is 81.13%, the qualified rate of largescale pig farms is 95.83%, and the pass rate of freerange pig farms is 95.83%. The ratio is 67.50%. Conclusion: The CSF and FMD immune antibodies in Huishui County are generally qualified. The immunity qualification rate and qualified number ratio of freerange households are extremely significantly lower than those of largescale farms (P< 0.01), and the risk of epidemics is higher. The animal disease prevention and control department in Huishui County should strengthen the monitoring and early warning of CSF and FMD in freerange households, and improve the awareness and level of CSF and FMD disease prevention and control in freerange households in a targeted manner.
