摘　　要：文章对大骨鸡快羽和慢羽2个群体(133日龄)进行体尺性状分析。结果表明:慢羽群体的主要体尺和体重指标显著高于快羽群体(P<0.05);公鸡的胸围、体斜长、龙骨长和胫长等变异系数较大,体型差异较大;体重与体斜长的正相关性最高(0.776),体重选择以选择体斜长为主。In the paper,the body-shape characters on fast-feathered and slow-feathered of big bone chicken(133-days)were analyzed. The results showed that the main body-size and body-weight of slow-feathering were significantly higher than that of fast-feathering(P<0.05). Bust circumference, body oblique length, keel length and shank length of roosters had higher coefficient of variation and greater difference in body shape. The positive correlation between body weight and body oblique length was the highest(0.776), and body weight was mainly selected by body oblique length.
