摘要: [目的] 分析二郎山山地鸡产蛋性能的选育效果。[方法] 通过测定该群体两品系、两世代的多种产蛋性状,对其产蛋性状进行多重比较和相关性分析。[结果] 结果表明:二郎山山地鸡的大部分产蛋性状在世代间和品系间差异显著(P<0.05);开产日龄和开产蛋重呈极显著的正相关(P<0.01),与开产体重、300日龄产蛋量呈极显著的负相关(P<0.01);开产体重与300日龄产蛋量呈显著正相关(P<0.05);开产蛋重和300日龄产蛋量呈极显著的负相关(P<0.01)。[结论] 二郎山山地鸡经过两个世代的选育,其产蛋性能的提高效果比较明显,为二郎山山地鸡的后续选育提供了参考资料。

Abstract: [Objective] In order to analyze the breeding effect of laying performances between two generations of Erlang mountainous chickens.[Method] The determination of several laying traits,comparison of laying performance and correlation analysis among laying traits were carried out.[Results] The results showed that there were significantly differences between the strains of two generations of laying performances (P<0.05);the age at first egg (AFE) was significantly positive correlated with egg weight at first egg (EWFE) (P<0.01),but negatively correlated with body weight at first egg (BWFE) and egg numbers at 300 d old (EN300) (P<0.01);BWFE was positively correlated with EN300 (P<0.05);there was significantly negative relation between EWFE and EN300 (P<0.01).[Conclusion] The effect of breeding between two generations of Erlang mountainous chickens was significant,and the study provided basic information for further breeding in Erlang mountainous chickens.

Key words: Erlang mountainous chickens, laying performances, selecting progress, correlation analysis
