摘要
研究旨在了解岳阳地区生猪标准化养殖场免疫水平,采用ELISA方法对岳阳地区8个生猪标准场采集的共480份血清进行口蹄疫O型抗体、口蹄疫A型抗体、猪瘟抗体等7个项目的检测。结果显示,全年免疫水平低于农业农村规定的最低标准(70%)有15场次,有一个场检测出猪伪狂犬病gE抗体阳性;部分场次不同时期间口蹄疫A型抗体、蓝耳病抗体和猪伪狂犬病gB抗体的抗体水平存在显著差异;除下半年口蹄疫O型抗体水平各场次间差异不显著外,其他时期不同场间的抗体水平存在显著场间差异。研究表明,岳阳市生猪标准化养殖场的免疫水平不一,且存在时间和地区差异。为保障疫苗的保护力,岳阳市生猪标准化养殖场应加强易感猪群的免疫,有针对性地制定免疫计划。
The aim of this study was to understand the immunity level of standardized pig farms in Yueyang City.A total of 480 sera collected from eight standardized pig farms in Yueyang City were detected by ELISA method with seven items,such as FMD-O antibody,FMD-A antibody and swine fever antibody.The results showed that the immunization level was lower than the minimum standard(70%)of agriculture and rural areas in 15 farms,and one farm was positive for pseudorabies gE antibody.There were significant differences in the antibody levels of foot-and-mouth disease type A antibody,blue ear antibody and porcine pseudorabies gB antibody during different farms.There were significant farm to farm differences in antibody level of FMD type O in the second half of the year,except that there was no significant difference between different farms.The study showed that the immunity level of Yueyang standardized pig farms was different,and there were time and regional differences.In order to ensure the protective power of vaccine,Yueyang standardized pig farm should strengthen the immunization of susceptible pigs and formulate targeted immunization plans.
