| 摘 要： | 为探索猪繁殖与呼吸综合征(PRRS)的综合防控技术,采用现场调查、血清学监测和病原学诊断等方法,对贵州省2007年3月至2009年10月采集的PRRS样本进行了血清学流行病学调查和病原学诊断,对比了不同疫苗免疫效果,测定了仔猪母源抗体的消长规律,确定了不同免疫/感染状态下仔猪首免日龄,结果表明,PRRS易于7~10月份流行;仔猪和能繁母猪的感染率较高,达到96.15%和74.73%;弱毒疫苗免疫效果优于灭活疫苗;哺乳仔猪母源抗体水平随着日龄增长逐渐降低,因此免疫PRRSV母猪所产仔猪的首免日龄定为17~20日龄;曾感染PRRSV母猪所产仔猪首免日龄定为30~34日龄。同时调查了猪场中蚊蝇携带PRRSV情况,初步证明猪场中的蚊蝇均可携带PRRSV;通过消毒试验对比进行了综合防治措施效果初探,取得理想结果。为贵州省PRRS综合防控措施的实施和推广提供了技术支撑。

| Abstract: | In order to explore the synthesis prevention and control technology of PRRS,field investigation,serology monitoring and etiology diagnosis were used to analysis the PRRS sample which occurred in Guizhou province,March,2007 to October,2009.Different vaccine immunity effect and newborn pig’s female source immune body increase and decrease rule also be researched.The study of serology monitoring and etiology diagnosis indicated that PRRS easy transmit in July to October;the newborn pig and sow’s disease infected rate are high,achieves 96.15% and 74.73%;the modified live virus vaccine are superior to killed preparations;the immunity PRRSV sow produces newborn pig’s head to exempt the date age to decide as on 17 to 20 d;once infected the PRRSV sow to produce newborn pig to exempt the date age to decide as on 30 to 34 d.Investigated the possibility of the mosquito and fly of carrying the PRRSV in the pig farm and proved that mosquito and fly portable carry PRRSV. |
