云南半细毛羊不同发育阶段皮肤毛囊性状的发育规律研究
A Study on the Development of Skin Follicle Traits in Yunnan Semi-fine Wool Sheep of Different Age
摘要
Abstract
The skin specimens taken from 58 sheep at birth,weaning,sixmonthand one year of age were cut serially on the horizontal and vertical direction.The morphological structure and the follicle traits were observed and evaluated at sebaceous gland level.The follicle traits include primary follicle density,secondary follicle density,total follicle density,ratio of secondary to primary follicle(S/P),primary fiber diameter,secondary fiber diameter,mean diameter,skin thickness and derma thickness(mm).The results showed that the follicle groups generally consisted of three primary follicles with a varying number of secondary follicled and were oval-shaped with abundant sebaceous gland and fewer curl.The skin construction and the follicle traits are significant different between birth and other three age groups,however,there was no significant differexe (P>0.05)among weaning,six-month and one year of age,suggesting that the skin follicle traits were completely developed at the weaning age (four-month).The toatl follicle density (Per mm)at birth,weaning,six-month and one year of age was 47.44±7.73,29.00±6.49,29.29±6.42 and 29.79±6.07 respectively;The ratio of secondary to primary follicle(S/P) was 3.52±0.91,6.00±1.13,6.63±0.95 and 7.39±1.26 respectively.There was no significant difference between singles and twins in the development of skin follicle except the follicle number before weaning.关键词
