摘要: 为了合理开发和利用东涛鸡,测定了300日龄成年东涛鸡(公母各30只)的体质量及体尺性状指标,利用相关分析及通径分析的方法研究影响东涛鸡体质量的最主要因子,研究各体尺性状对体质量的直接和间接作用大小。结果显示,东涛鸡公鸡的体斜长是影响体质量的最主要因子,其独立效应、通径系数和相关系数分别为0.533、0.730和0.731;母鸡的胫围是直接影响体质量的最主要因子,其独立效应、通径系数和相关系数分别为0.176、0.419和0.518。母鸡的胸深和体斜长对体质量的间接影响较大,其累计效应分别达0.550和0.379。

Abstract: To fully explore and utilize the Dongtao chicken(30 roosters and 30 hens),this study collected data of body mass and body measurements of 300-day-old adult Dongtao chickens.Correlation analysis and path analysis were conducted to research the main influencing factor on body mass.The direct and indirect effect sizes of each body measurement on body mass were calculated.The results showed that the body length was the main factor influencing body mass in roosters.Its independent effect,path coefficient and correlation coefficient were 0.533,0.730 and 0.731,respectively.Shank circumference was the main factor influencing body mass in hens and its independent effect,path coefficient and correlation coefficient were 0.176,0.419 and 0.518,respectively.In hens,the breast depth and body length had relatively high indirect effects on body mass,with the cumulative effects being 0.550 and 0.379.
