探讨修水黄羽乌鸡体质量、体尺与屠宰性状的相关关系，为修水黄羽乌鸡品种鉴定及选育提供依据。试验对150日龄修水黄羽乌鸡的体质量、体尺及屠宰性状进行测定，并对各指标进行相关性分析。结果表明：修水黄羽乌鸡属小型乌鸡品种；体质量、体斜长、龙骨长、胸深、胫长和胫围在公母间存在极显著差异（P＜0．01），且平毛系各项体尺指标显著高于翻毛系（P＜0．05）；体质量与体斜长、龙骨长、胫长、胸深、胸围、骨盆宽均有显著差异（ P＜0．05）或极显著正相关（ P＜0．01）；修水黄羽乌鸡产肉性能优良，且平、翻毛系间差异不显著；体斜长、龙骨长、胸围、胸深与屠宰率、半净膛率、全净膛率呈显著相关（ P＜0．05）或极显著正相关（ P＜0．01），其余指标间亦有不同程度的相关。

The purpose of this study was to investigate the correlations among body weight ,body size and traits of Xiushui yellow silky chicken in order to provide scientific basis for species identification and breeding and improving the native breeds .The body weight ,body size and carcass traits of Xiushui yellow silky chicken at 150 days were measured and the correlations among these traits were analyzed .The results showed that Xi-ushui yellow silky chicken was a small-sized breed and there were very significant differences between the male and female chickens in body weight ,body slope length ,fossil bone length ,breast depth ,shank length and the measures of shank circumference ( P<0.01) ,and the measures of the normal series were significantly higher than those of frizzled-feather one between ( P<0.05);body weight had significant positive correlation ( P<0.01) with body slope length ,fossil bone length ,shank length ,breast depth ,breast circumference and pelvic width .Xi-ushui yellow silky chicken ’ s meat performance was good and there were no significant difference between normal and frizzled-feather series .Body slope length ,fossil bone length ,breast circumference ,breast depth had signifi-cant positive correlation ( P<0.01 ) with percentage of slaughter weight , carcass weight and half-eviscerated weight ,eviscerated weight .There were correlations of various degress among others measures .
