Correlation Analysis of Ecological Traits and Economic Traits for Chinese Native Chicken Breeds
摘要
Abstract
The obj ective of this study was to investigate the correlation of ecological traits on body size traits and economic traits (body size traits and slaughter traits)in Chinese native chicken breeds and reveal the essential connection of three group traits.In this study,simple correlation analysis and canonical correlation analysis (CCA)were applied to estimate the relationship be-tween local 6 ecological traits and 8 body size traits,6 ecological traits and 8 slaughter traits,8 body size traits and 8 slaughter traits of Chinese native chicken breeds.The result of ecological traits and slaughter traits suggested that the first canonical correlation coefficient was 0.536 (P<0.01),the value of pct was 55.046% for the total correlation information.It showed that the cor-relation between two sets of traits mainly by mean annual temperature and dressed weight closely related to the cause,the lower mean annual temperature,the heavier dressed weight.The result of ecological traits and body size traits suggested that the first canonical correlation coefficient was 0.679 (P<0.01),the value of pct was 54.118%,for the total correlation information.It showed that the correlation between two sets of traits mainly by latitude and shank girth closely related to the cause,the higher latitude,the smaller shank girth.The second canonical correlation coefficient was 0.556 (P<0.05),the value of pct was 28.251% for the total correlation information.It showed that the correlation between two sets of traits mainly by forst free period and chest bone length closely related to the cause,the longer forst free period,the longer chest bone length.The result of body size traits and slaughter traits suggested that the first canonical correlation coeffi-cient was 0.901 (P<0.01),the value of pct was 81.063% for the total correlation information.It showed that the correlation between two sets of traits mainly by chest bone length and dressed weight closely related to the cause,the longer chest bone length,the greater dressed weight.关键词
