摘要: 以3个批次的桂香鸡为研究对象,分析120日龄时桂香鸡的胫长、胫围以及体重之间的相关性。研究结果表明,第3批桂香鸡的120日龄体重和胫围显著高于第1批(P〈0.05),第2批和第3批桂香鸡的120日龄胫长显著高于第1批(P〈0.05)。相关分析表明,第1批桂香鸡120日龄体重和胫长以及胫围之间存在极显著的相关(P〈0.01),相关系数分别为0.583和0.623;120日龄胫长和胫围之间存在极显著的相关(P〈0.01),相关系数为0.369。第2批和第3批数据合并分析表明,桂香鸡120日龄体重和胫长以及胫围之间存在极显著的相关(P〈0.01),相关系数分别0.605和0.726;120日龄胫长和胫围之间存在极显著的相关(P〈0.01),相关系数为0.463。研究结果为桂香鸡胫长、胫围与体重性状的选择,尤其是桂香鸡胫长、胫围与体重性状的综合选择提供了参照。

Abstract: In the present study,the correlation between shank length,shank girth and body weight of 120-day-old Guixiang Chicken was assessed using three batches of Guixiang Chicken.The results showed that the third batch of Guixiang Chicken had significant higher body weight and shank girth at the age of 120 days than that of the first batch(P〈0.05),and the second and third batches had significant higher shank length at the age of 120 days than that of the first batch(P〈0.05).The correlation analysis showed that the first batch displayed very significant correlation between the body weight and shank length as well as shank girth at the age of 120 days(P〈0.01),and the correlation coefficients were 0.583 and 0.623,respectively;there was very significant correlation between the shank length and shank girth at the age of 120 days in the first batch(P 0.01),and the correlation coefficients was 0.369.The analysis results based on the combined data of the second and third batches showed that the very significant correlation between the body weight and shank length as well as shank girth at the age of 120 days was observed(P〈0.01),and the correlation coefficients were 0.605 and 0.726,respectively;the very significant correlation between the shank length and shank girth at the age of 120 days was also observed(P〈0.01),and the correlation coefficients was 0.463.These results lay a theoretical foundation for the selection of body weight,shank length and shank girth traits in Guixiang Chicken,especially for the combined selection of the three traits.
