山羊关节炎—脑炎的净化技术研究

The Cleaning Technic Study on Caprine Arthritis-Encephalitis

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。
