贵州规模养猪场主要疫病的流行状况

Prevalence of Epidemic Disease in Scale Pig Farms in Guizhou Province

为给贵州省规模养猪场疫病的预防与控制提供参考,对2008—2010年贵州省动物疫病研究室检测与诊断的规模养猪场疾病发生情况进行了整理分析。结果表明:在免疫猪群中,仍有猪瘟、猪蓝耳病、猪伪狂犬病、猪细小病毒病和猪圆环病毒病的发生,其检出率分别为16.4%、17.8%、16.8%、12.8%和17.1%,在未免疫猪群中的检出率为43.7%、46.3%、26.5%、26.8%和45.6%,且多为混合感染。猪蓝耳病和猪瘟仍是危害规模养猪场的2种重要疫病,且猪圆环病毒病存在严重的隐性感染,多种病原体混合感染趋势加重。

Data of detection and diagnosis on pig diseases,collected from institute of animal diseases in Guizhou Province during 2008 to 2010,were analyzed to provide a reference for prevention and control of pig diseases in scale farms in Guizhou Province.The results showed that the incidence rates of classical swine fever（CSF）,porcine reproductive and respiratory syndrome（PRRS）,swine pseudorabies（PR）,porcine parvovirus infection（PP） and porcine circovirus infection（PCVD） were respectively 16.4%,17.8%,16.8%,12.8% and 17.1% in the immuned pigs.While 43.7%、46.3%、26.5%、26.8% and 45.6% respectively in the unimmuned pigs,and these cases were mostly mixed infections.The results indicated that PRRS and CSF were two important diseases harmful to scale pig farms,and there was serious latent infection of PC and the trend of mixed infection of multiple pathogens increased.
