摘要: [目的] 分析蛋肉兼用系HS2黄胫与青胫对生产性能的影响。[方法] 试验分别测定了两群体的开产日龄、开产体重、开产蛋重、300日龄体重、300日龄蛋重和300日龄产蛋量,并对两群体21到43周龄的产蛋曲线进行了分析。[结果] 统计分析结果表明胫色对开产日龄、开产体重、开产蛋重、300日龄产蛋量、300日龄鸡重、300日龄蛋重的影响不显著(P>0.05);两种胫色的产蛋曲线接近。相关分析结果表明,开产日龄与开产体重、开产蛋重呈显著正相关(P<0.05),与300日龄产蛋量、300日龄蛋重呈显著负相关(P<0.05);开产体重与开产蛋重呈显著正相关(P<0.05);开产蛋重与300日龄蛋重呈显著正相关(P<0.05)。[结论] 蛋肉兼用系HS2青胫和黄胫群体生产性能差异不显著,可保留两群体,分别培育青胫系和黄胫系。

Abstract: [Objective] In order to analyse the differences of laying performance between yellow and black shank groups in dual-purpose line HS2. [Method] We measured their body weights and egg weights at ages laying first egg and 300 d.Age laying first egg and total egg number for 300 d were also measured with these traits.Analysis the two group's egg production curves between 21 weeks to 43 weeks. [Results] There is no significant differences between two groups on all traits (P>0.05).The yellow and black shank groups had the same laying curve shapes.Correlation analysis results indicated that age at first egg was positively correlated with body and egg weight at first egg (P<0.05),whereas it was negatively correlated with egg number for 300 d and body weight at 300 d (P<0.05).Body weight at first egg was positively correlated with egg weight at first egg (P<0.05).Egg weight at first egg was positively correlated with egg weight at 300 d (P<0.05). [Conclusion] No difference of laying performance between the yellow and black shank populations.Thus we can keep both populations,and breed them as yellow shank and black shank lines,respectively.
