摘要
对不同屠宰日龄公、母鸭的生长发育规律及各体尺性状与体重的相关性进行了分析。结果表明,除胫围外,其他性状均随着日龄的增加呈逐渐增加的趋势。对体重与体尺指标进行相关性分析表明,在42、56、70、90日龄,体重均与龙骨长、半潜水长、胸宽、骨盆宽等各项指标呈极显著相关,而与其他性状的相关性未在所有日龄都达到显著水平。
The growth and development regularity of body size traits of black feather duck at different slaughter age of days and its correlation with body weight were analyzed. The results showed that except shank circumference, the traits presented a growing trend with the increase of age of days. The body weight was significantly correlated with keel length, semi-submersible length, chest width and pelvic width at 42, 56, 70, 90 days of age. The correlation with other traits were not significant at all slaughter days.
