| 摘 要： | 测定200只黑羽番鸭216～315日龄(100 d)的产蛋数及315日龄体尺、体质量并进行相关性分析。结果表明:黑羽番鸭产蛋数与体质量、半潜水长、骨盆宽、胸宽等呈极显著正相关,与体斜长、胸深呈显著正相关,与龙骨长、胫长、胫围相关性不显著;体质量与体斜长、龙骨长、胫长、半潜水长、胸宽、胸深、骨盆宽等呈极显著正相关,体质量与胫围等呈显著正相关。

| Abstract: | In order to study the correlation between body indexes and egg production, body size and body mass of 200 black muscovy ducks at age of 315 days, and the number of laying eggs at age of 216-315 days (in a total of 100 days) were measured. The correlation analysis of measured indexes were then carried out. The results showed that the laying production was positively correlated with body mass, semi-submerged long, chest width and pelvic width of black muscovy ducks, and positively correlated with body oblique length and chest depth, but not correlated with keel length, shank length and shank circumference. The body oblique length, keel length, shank length, semi-submerged length, chest width, chest depth and pelvic width were positively correlated with body mass, and body mass was positively correlated with tibia circumference. The results of this study provide a theoretical basis for accurate and scientific selection and breeding of muscovy duck. |
