圈养东北马鹿鹿茸生长研究

2012年3月8日至5月22日,对北京动物园圈养的一只雄性东北马鹿鹿茸生长进行了研究。每间隔8～12d对鹿茸进行拍照,按比例测算鹿茸的相对长度,在锯鹿茸当日测定鹿茸重量。结果表明：圈养条件下,东北马鹿鹿茸主干生长随时间变化呈＂S＂型生长曲线,即呈缓慢、快速和减速生长3个阶段。第1阶段为第0～29天,平均生长速度为0.17cm/d;第2阶段为第30～56天,平均生长速度为1.30cm/d;第3阶段为第57天后,鹿茸平均生长速度为0.94cm/d。鹿茸3个阶段生长速率差异显著（P〈0.01）。第72天鹿茸锯下时重量4.0kg,平均增重0.05kg/d;右角主干长度54.5cm,平均生长速度0.76cm/d;左角主干长度56.5cm,平均生长速度0.78cm/d。

Study on Deer Antler Growth Behavior of Captive Manchurian Wapiti

From March 8th , 2012 to May 22nd , 2012 , the deer antler growth behavior of a male Cervus elaphus xanthopygus was studied in Beijing Zoo using focal animal sampling method. The sampling intervals were 8～12 days. Different stages of deer antler were taken pictures , the data of the deer antler relative lengths were calculated , and the deer antler was weighted when amputated. The results showed that the growth of the deer antler main branch of the captive manchurian wapiti was in a ' S ' shaped growth curve , which composed by three stages , with time going showed slow , fast and deceleration respectively. The first stage was at 0～29 days of the deer antler trunk growth , with an average growth rate of 0.17 cm/d. The second stage was at 30～56 days , with an average growth rate of 1.30 cm/d. The third stage was after 57 days , with average growth rate of 0.94 cm/d. The growth rate in three stages were significantly different ( P<0.01 ) .The deer antler was 4.0 kg when sawed after 72 days. The weight increased by 0.05kg/d.The right main branch of the deer antler was 54.5 cm in length , and the average growth rate was 0.76 cm/d. The left main branch of the deer antler was 56.5 cm in length , and the average growth rate was 0.78 cm/d.
