为了解惠水县猪瘟(CSF)和猪口蹄疫(FMD)免疫抗体情况,预判其流行趋势和评估其发生风险,试验采用ELISA检测方法,2022 年累计检测惠水县养猪场(户)CSF样品 2099 份,猪O型口蹄疫(FMD-O)样品 1797 份,结果表明:(1)CSF免疫抗体总体合格率为 90.14%,规模猪场合格率为 93.11%,散养户为 84.60%,规模猪场合格数比率为 97.87%,散养户的合格数比率为75.26%;(2)FMD-O 免疫抗体总体合格率为 91.96%,规模猪场的合格率为 96.72%,散养户为81.13%,规模猪场合格数比率为 95.83%,散养户的合格数比率为 67.50%.结论,惠水县 CSF和FMD免疫抗体总体合格,散养户的免疫合格率和合格数比率极显著远低于规模场(P<0.01),发生疫情的风险较高.惠水县动物疫病防控部门应加强散养户 CSF 和 FMD监测预警,有针对性地提高散养户CSF和FMD疫病防控意识和水平.
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 immu-nity 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 aware-ness and level of CSF and FMD disease prevention and control in free-range households in a targeted manner.
