摘要: [目的] 探讨二郎山山地鸡蛋用品系的选育进展。[方法] 试验通过比较二郎山山地鸡蛋用品系第一、第二世代孵化和产蛋性状,并对第二世代产蛋性状做相关分析。[结果] 第二世代的受精率、孵化率、产蛋高峰期的产蛋率和高峰期持续时间均优于第一世代,第二世代开产日龄极显著大于第一世代(P<0.01),但300日龄产蛋量差异不显著;第二世代开产日龄与开产体重呈极显著正相关(r=0.18,P<0.01),与开产蛋重极显著正相关(r=0.24,P<0.01),与300日龄产蛋量极显著负相关(r=-0.20,P<0.01);开产体重与开产蛋重极显著正相关(r=0.19,P<0.01);开产蛋重与300日龄产蛋量显著负相关(r=-0.11,P<0.05)。[结论] 通过两个世代的选育,二郎山山地鸡蛋用品系的选育效果明显。

Abstract: [Objective] To explore the breeding effect of the laying-strain of Er-lang mountainous chickens.[Method] The hatching and laying performances was compared between generations 1 and 2.In addition,we analyzed the correlation among laying traits of generation 2.[Results] The results showed that fertility rate,hatching rate,the highest laying rate and duration time in egg production peak period of generation 2 were higher than generation 1.Additionally,age at first egg of generation 2 was highly significantly older than generation 1,while no significant difference of egg production in 300 days was detected between the two generations.Correlation analysis in generation 2 revealed that age at first egg (AFE) were highly significantly positive correlated with body weight at first egg (BWFE) (r=0.18,P<0.01) and egg weight at first egg (EWFE) (r=0.24,P<0.01).Whereas AFE was extremely significantly negative correlated with egg number at 300 days (EN300) (r=-0.20,P<0.01).Furthermore,BWFE were highly significantly positive correlated with EWFE (r=0.19,P<0.01),EN300 was negative correlated with EWFE (r=-0.11,P<0.05).[Conclusion] Dramatically progress has been made in selection of Egg-production line of Er-lang mountainous chickens.
