摘要
笔者对安徽省宣城市不同地理环境的6个市(县)共21个集约化养猪场的1520头妊娠母猪,进行了猪细小病毒病流行的调查研究。其中,发生繁殖障碍综合征的猪671头,占44.1%。1520头妊娠母猪中,共产仔7799头,其中,死仔猪1530头,占产仔总数的19.6%。在671头繁殖障碍综合征的妊娠母猪中,共抽样207头份血清进行猪细小病毒(PPV)、衣原体(Cp)、布鲁氏杆菌(Br)及乙型脑炎病毒(JEV)的血清学检查。其中,猪细小病毒抗体阳性反应高达79.8%。研究结果表明,该市繁殖障碍综合征的主要原因是猪细小病毒感染。因此,应将防制繁殖障碍综合征的主要对象从布鲁氏杆菌病转移到猪细小病毒病,并建立猪群中定期血清抗体监测制度,加强猪细小病毒病的流行防疫工作。
The epidemiological investigation on PPV disease was performed among 1 520 pregnant sows of 21 intensive pig farms of 6 cities （counties） with different geographic environments of Xuancheng City in Anhui Province by the writer. Among them, the reproductive handicap syndrome occurred on 671 sows, which accounted for 44.1%.The 1 520 pregnant sows produced 7 799 piglets, among which the 1 530 piglets were dead and the dead piglets accounted for 19.6 % in the total piglets. Among 671 pregnant sows with reproductive handicap syndrome, 207 shares of serum were sampled for serologic examination on PPV, Cp, Br and JEV. Among them, the positive response of antibody to PPV was up to 79.8 %. The study results indicated that the main cause of reproductive handicap syndrome was PPV infection in the city. So, the main object of preventing reproductive handicap syndrome should be transferred from Br disease to PPV disease and the periodic monitorring system of antibody in serum of pig group should be set up to strengthen the epidemic prevention of PPV disease.
