摘要:
猪繁殖与呼吸综合征一直是影响养猪业最严重的疾病,通过对1个PRRSV阴性猪场母猪突发大量流产的病例进行抗体和病原检测,细菌分离鉴定和MIC测定,然后制定和实施防控措施和评价指标。结果发现:(1)50份流产母猪PRRSV抗体检测阳性率100%;(2)母猪血清、流产物、睾丸去势液及保育猪组织样本,PRRSV阳性率分别为90.0%、80.0%、100.0%及85.7%,但所有样本CSFV、PRV、PPV及SIV病原均为阴性;(3)4份PRRSV阳性样本经ORF3、ORF5及Nsp2测序和比对,结果均与NADC30同源性最高;(4)保育猪组织样本分离到链球菌和副猪嗜血杆菌,MIC测定结果显示氟苯尼考和阿莫西林对上述2种分离菌最敏感;(5)控制措施实施后的3个月,母猪的流产率从发病期的43.6%,下降至3.6%,断奶7 d内配种率从发病期的63.3%上升至87.5%,哺乳仔猪和保育猪的死亡率分别从发病期的28.4%和38.8%下降至3.8%和4.7%。通过对该病例的诊断和疫情分析,采用灭活苗免疫接种和药物保健综合防控措施可快速取得效果,为规模化种猪场的PRRSV暴发防控提供参考。
