角是反刍动物有别于其他动物的明显特征(Wang et al.,2019)。与牛科动物、羊科动物的洞角不同,鹿角为实心骨质、可年度周期性脱落、其分枝和重量受到众多因素的影响,是鹿类保护、养殖、育种领域关注的焦点问题(Bowyer,1991)。幼鹿每增长...角是反刍动物有别于其他动物的明显特征(Wang et al.,2019)。与牛科动物、羊科动物的洞角不同,鹿角为实心骨质、可年度周期性脱落、其分枝和重量受到众多因素的影响,是鹿类保护、养殖、育种领域关注的焦点问题(Bowyer,1991)。幼鹿每增长1岁,角增加1个分枝;角直径和重量也随之增加(夏志强等,2023);同一年龄组同一个体的不同阶段,茸生长速度和重量增加也不相同(Hassanin et al.,2012;李春义,2017;夏志强等,2023);鹿茸软骨与机体其他软骨组织不同,内有血管(鲍加荣等,2008;Chen et al.,2019),可供给茸生长所需的营养(Clements et al.,2010;Lin et al.,2019);血管内皮生长因子(Vascular endotheli‐al growth factor,VEGF)的含量变化对鹿茸的生长速度、茸直径、分枝数、分枝方向及角重和形态发育有重要影响(Clark et al.,2006)。展开更多

We collected velvet tissue from Père David’s deer, sika deer (Cervus nippon) and fallow deer (Dama dama). After extracting steroids from velvet tissue with ether, we analyzed the estrdiol concentrations using radioimmunoassay technique. We found that: (1) estradiol concentrations were significantly different in the velvet tissue of these three cervids (P<0.05) and (2) Père David’s deer stags had the highest velvet tissue estradiol concentrations, 105.29±27.53 pg/g.
