| 摘 要： | 通过对二郎山山地鸡两个品(SD02、SD03)系之间产蛋性能差异性的比较以及产蛋性状间的相关分析,结果表明:二郎山山地鸡两个品系间多个产蛋性状间差异显著,SDO2品系产蛋性能明显优于SD03品系;开产日龄与开产体重呈极显著的正相关(P<0.01),与开产蛋重呈显著相关(P<0.05);开产体重与开产蛋重呈显著正相关(P<0.05),与开产后第4个月产蛋量呈极显著负相关(P<0.01);开产当月产蛋量与后期产蛋量呈极显著正相关(P<0.01)。

| Abstract: | Through the comparison of the laying performances and the analysis of the correlation among laying traits between the two strains of Erlang mountain chickens(SD02,SD03),the results showed that there were significant difference in the most of laying performances between the two strains,and the laying performance of the SD02 strain was much better than that of the SD03 strain.The age at first egg(AFE) was significantly in positive correlation with body weight at first egg(BWFE)(P<0.01),and positively correlat... |
