吉林白鹅羽毛(绒)生长发育规律的研究

本试验对吉林白鹅羽毛(绒)生长发育规律进行了研究。分别在34、44、54、64日龄随机抽取15只试验鹅,以颈部放血法屠宰后,采集翅部、背部、腹部、尾部羽毛(绒),主要测量羽毛的羽轴、羽枝、羽根及羽绒的长度。结果表明,羽毛的生长是一个渐变的过程,不同部位的羽毛成长速度不同,换羽时间也不一致;同一部位的羽绒、羽枝、羽轴随着日龄的增长,变化趋势基本一致,而羽根的变化趋势与羽绒、羽枝、羽轴的相反。

Study on Growing and Development Rule of Jilin Geese Feather or Down

This experiment studied the growth and development rules of Jilin geese feather(eiderdown).15 geese were selected randomly on the 34th,44th,54th and 64th day.After those geese were slaughtered by means of the neck bloodletting,the feathers of abdomen,wing,back and tail were collected.The main measurement included the length of feather axis,feather sticks,feather roots and down.The results showed that the down,the weather sticks and the feather axis in the same parts have the same growth trend,while the feather roots have the opposite growth trend,and the feather in different parts had different growth rate.
