Abstract: In order to investigate the correlation between body size traits and laying performance of Qingyuan partridge hen,the number of eggs laid by 893 Qingyuan partridge hens at 18 to 40 weeks of age(22 weeks of age)was calculated and body size and body weight were measured at 18 weeks of age.The correlation analysis results showed that there was a significant negative correlation between tibial circumference,tibial length / body weight and egg production(P<0. 01).There was a outstanding negative correlation between tibial length and egg⁃laying number(P<0. 05). There was a significant positive correlation between body weight and egg⁃laying number(P<0. 01). When the tibial length/body weight ratio of Qingyuan partridge hen was higher than 5. 5 cm/kg,the average egg production was the lowest.During breeding,both the conventional body size indexes and the correlation between tibia length/body weight and cumulative egg production of 40 weeks age should be considered for early breeding of egg⁃laying performance.

Key words: Qingyuan partridge hen, Body weight, Body size traits, Egg production, Correlation analysis

摘要: 为探讨清远麻鸡母系体尺性状与产蛋性能的相关性,合理选择并利用早期选育指标,统计893只清远麻鸡母系18~40周龄(22周)的产蛋数,并测定其18周龄的体尺、体质量,相关分析结果表明,清远麻鸡母系的胫围、胫长/体质量与产蛋数之间呈极显著负相关(P<0.01),胫长与产蛋数之间呈显著负相关(P<0.05),体质量与产蛋数之间呈极显著正相关(P<0.01);清远麻鸡的胫长/体质量大于5.5 cm/kg时,其平均产蛋数值最低。以上结果表明,清远麻鸡母系产蛋性能选育,除要选择常规的体尺指标外,还要综合考虑开产时胫长/体质量和40周龄累计产蛋数间的相关性。
