摘　　要：为探究广西麻鸡活重及体尺性状与个体产蛋量的相关性,以某公司提供的广西麻鸡为观测对象,连续30 d产蛋数据为依据,进行了初步研究和分析。结果显示,个体最高产蛋数24个,最低0个,产蛋数集中分布在10~19个,产蛋数在该区间的个体共71羽,占鸡群的46.71%。广西麻鸡产蛋期活重与产蛋量呈极显著负相关(P<0.01),两者相关系数达到中度相关(r=-0.647)。其他体尺性状包括体斜长、龙骨长、胫长与产蛋量的差异不显著(P>0.05)。综上所述,可以根据活重对广西麻鸡的选育做出指导,研究可为广西麻鸡育种工作提供数据参考。This experiment explores the correlation analysis between the live weight and body size of Guangxi Ma chicken and individual egg production.The observed objects are Guangxi Ma chickens provided by one company.Based on the 30-day consecutive egg production data,preliminary research and analysis were conducted.The results showed that the maximum number of eggs laid by individuals was 24,while the minimum was 0.The distribution of egg production was concentrated between 10-19 eggs,with a total of 71 individuals in this range,accounting for 46.71%of the flock.The live weight of Guangxi Ma chicken is strongly and significantly negatively correlated with egg production during laying period(P<0.01),with a moderate correlation coefficient between the two(r=-0.647).Other body measurements,including body slant length,keel length,and tibia length,showed no significant differences(P>0.05)in relation to egg production.In conclusion,selection based on live weight can be used for the breeding of Guangxi Ma chickens,and this study provides data reference for further advancement of breeding work for Guangxi Ma chickens.
