摘　　要：为了探究二郎山山地鸡育种过程中鸡白痢的净化效果,本研究采用全血玻板凝集方法检测SD02和SD03品系3个世代鸡群体中鸡白痢患病情况,并同时对每个世代中生产性能数据进行统计分析。结果显示,经过3个世代的鸡白痢净化淘汰,SD02和SD03品系各世代间的患病率差异极显著(P<0.01)。SD02品系中患病率与健雏率、育成阶段成活率、产蛋阶段成活率均呈显著负相关(P<0.05);SD03品系中患病率与育雏阶段成活率呈显著负相关(P<0.05)。以上结果表明,SD02和SD03中鸡白痢净化效果极显著,提高了鸡群的生产性能,为后续育种过程中清除鸡白痢奠定了理论基础。In order to explore the breeding process of Erlang Mountain chicken pullorum purifying effect, this study used whole blood glass plate agglutination method to detect lines SD02 and SD03 three generations chicken populations pullorum dis- ease situation, and also for the production of each generation performance data for analysis. The results showed that after three generations of purifying elimination,SD02 and SD03 prevalence among generations were extremely significantly different （P〈 0.01）. SD02 in the rate of prevalence of child health, breeding stage survival rate, egg stage survival rate was significantly negatively correlated（P〈0.05）. SD03 in the prevalence of brooding survival was significantly negatively correlated（P〈0.05）. These results suggested that SD02 and SD03 pullorum purifying effect in significantly and improved production performance of flocks, breeding process for the subsequent removal pullorum laid a theoretical foundation.
