2010～2013年田东县猪瘟免疫效果调查分析

2010～2013 Tiandong county investigation of swine fever immune

利用正向间接血凝试验采集田东县2010-2013年种公母猪、保育仔猪和生长育肥猪经过猪瘟疫苗一免、二免后28d的血清和未免疫的哺乳仔猪血清共2606份进行猪瘟免疫抗体检测,观察抗体水平变化情况,并对各生长阶段猪群的免疫效果进行调查分析。结果表明：2010-2013年猪群猪瘟抗体合格率分别为73.44%、76.08%、80.87%、86.22%,平均合格率为79.24%,总体呈逐年上升趋势;种公母猪平均合格率最高,达91.55%,其次为生长育肥猪和哺乳仔猪,平均合格率分别为84.19%、72.25%,保育仔猪最低,平均合格率为65.92%;一免、二免的平均抗体合格率分别为51.24%、82.72%,二免显著高于一免。结果表明：各个猪场应对保育仔猪有针对性的免疫并及时淘汰经二次免疫以上抗体不合格的种公母猪,推行二次强化免疫工作,以提高猪群猪瘟抗体合格率。

Use indirect hemagglutination test collection Tiandong 2010~2013 stud sows, nursery pigs and finishing pigs in a classical swine fever vaccine through free, serum-free after two and unvaccinated piglets serum total of 2606 copies were 28 d Classical swine fever immunization antibody detection, antibody levels observed changes, and the effect of different growth stages of herd immunity investigation and analysis.
