摘要
为制定三穗鸭的地方标准,试验测定了210只0～17周龄原种三穗鸭的平均周增重,并于17周龄(120日龄)进行了体尺测定和相关分析。结果表明,1～17周龄公鸭的绝大多数周增重之间无显著性差异(P>0.05);公母鸭间的体斜长、半潜水长、龙骨长、胫围、胸宽、胸深极显著高于母鸭(P<0.01);公母鸭间的胫长和骨盆宽差异不显著(P>0.05)。与1991年制定的三穗鸭地方标准比较,在120日龄体重方面表现出一定的差异,外貌与体尺符合三穗鸭的品种特征。
To formulate the local standard of Sansui duck,210original species of Sansui ducks from 0week-old to 17-week-old were used in an growth experiment,the average weekly weight gain and the body size at 120days of age（17weeks）were measured,and a correlation analysis based on body size was conducted between females and males.The results showed no significant difference in the vast majority of weight gain from 1-17weeks of age;there were significant differences between male duck and female duck on body length（P〈0.01）,semi-submersible,keel length,shank girth,chest width and chest depth;there was no significant difference on tibia length and pelvic width（P〉0.05）.Compared with the local standards of Sansui duck enacted in 1991,some differences could be detected in current Sansui ducks in body weight at 120days of age,suggesting that the appearance and body size match the varieties type for Sansui duck.
