摘　　要：对北京油鸡两个品系216只母鸡,在17~49周期间每隔8周同时用全血和血清平板凝集试验进行鸡白痢检测对比分析。结果发现,血清检出阳性率高于全血检出阳性率,且血清检出阳性个体包含全血检出阳性个体;同时,检测结果也表明,33周龄鸡白痢阳性率达到最高,此后阳性率下降。因此,在鸡白痢净化过程中采用血清平板凝集法比全血平板凝集法检测更为敏感,在25~33周对北京油鸡群体增加一次鸡白痢净化更有助于加快净化进程。本研究可为其他地方品种种鸡鸡白痢检测工作提供参考。In this study, 216 hens from two lines of Beijing You chicken were investigated for the pullorum disease using the blood and ser-um plate agglutination methods. The samples were collected at an interval of eight weeks from 17 to 49 weeks. The results showed that thepositive rate of serum detection was higher than that of whole blood, and the positive chickens judged by the whole blood were almost includ-ed in those judged by serum. And the positive rate of pullorum reached the highest level at the age of 33 weeks, and then declined gradually.Therefore, the platelet agglutination test of serum is more sensitive than that of whole blood. It suggested that another test should be added at25 to 33 weeks old, which will accelerate the elimination speed of pullorum in Beijing You chicken. This study will be helpful for detection ofthe pullorum disease in other local breeds of chickens.
