2011—2013年广西地区猪瘟抗体监测及免疫效果分析

Analysis on Surveillance of Antibody Against Hog Cholera and Immune Effects in Guangxi Region During 2011 to 2013

为了解广西地区猪瘟的免疫抗体水平，采用正向间接血凝试验对采集自2011-2013年广西14个地市不同规模猪场的20271份血清样品进行了猪瘟抗体检测。结果表明，广西各地的猪瘟抗体水平存在一定差异，抗体合格率为64.4%~97.5%，平均合格率为84.9%，大型规模场和中小规模场的猪瘟抗体合格率较稳定，且保持在较高水平，分别为96.0%和87.5%；农村散养户和屠宰场/市场的抗体合格率相对较低，分别为82.7%和70.5%。
