摘要
对陕西省各地的山羊和两个种羊场的山羊关节炎—脑炎(CAE)进行流行病学调查,用OPP琼扩抗原进行血清学试验,并与CAE抗原作了对比,结果表明:西北农业大学(西北农大)畜牧站羊场奶山羊的血清学阳性检出率最高时为58.89%,千阳县种羊场奶山羊血清学阳性检出率最高时为3.45%,而陕西省各地的其他5种山羊的血清学阳性检出率为0;成年母羊的检出率明显高于青年母羊和羔羊;OPP抗原和CAE抗原阴性检出符合率较高,为100%,阳性检出符合率约为36%。检出率高的羊群中具有临床症状的羊很少;按照拟定的CAE净化方案,成功地在2个种羊场完成了CAE净化,使这两个种羊场最后连续4次和5次血清学阳性检出率为0,达到净化目标。
