中文摘要 | 本研究之目的在於利用酵素免疫分析法檢測臺北市立動物園內一頭雌性捲尾食蟻 獸糞便中孕酮(porgesterone)及雌二醇(estradiol)含量,以評估其生殖生理狀態。試驗結 果顯示,其動情週期約為35天,動情期與黃體期之糞孕酮平均濃度分別為511.8 ±156ng╱g 與1636.3±256.6ng╱g,雌二醇之平均濃度則分別為792.1±392.8ng╱g及62.2 ±27.lng╱g,而 懷孕期約為163天,胚埋植後糞孕酮與雌二醇平均濃度分別為1773± 414.8ng╱g與 558.6±211.6ng╱g。配種後,糞孕酮由538.6±321.7ng╱g上升至1610.5± 246.8ng╱g,雌二醇 由55.2±24.9上升至1034.9±453.1ng╱g。在未哺育仔獸的情況下,產後20天即可再發情配 種。根據上述內泌素濃度變化推測在配種後其胚有延遲埋植9週的現象。 |
英文摘要 | Up to now, the fecal steroid measuren1ent has been proven to be a very useful tool for monitoring the reproduction of mammals and gradually accepted for wild animal research, recently. However, this preliminary report may be the first one for Collared Anteater (Tamandua tetradactyla) on this purpose. A mature female Collared Anteater with her male companion housed in Taipei Zoo was used and her stool was collected once per week from August, 1991 to February, 1993. During this experin1ental period, she experienced two gestations in which she got a baby from the first one but died by dystocia from the second one. She did not nurse her baby and the baby was dead 3 days after delivery. The Collecteal fecal samples were frozen at -20℃. Following thawing, samples were extracted and analyaied for progesterone and estradiol by enzyme immuncassays. Results mainly based on the fecal steroid data were listed as follows. There are 35±2 days for the estrous cycle (Mean±S. D., N=4 observations) with fecal progestorone concentrations around 511.8±156ng/g and 1636.3±392.8ng/g and fecal estradiol level concentrations around 729.1±392.8ng/g and 62.2±27.1ng/g for the follioular phase and the mid-luteal phase, respectively. The mean geatation period was 163 days (162 and 164 days for the two geatations, respectively). A delayed implantation may exist during the pregnancy because the fecal progesterone levels were kept at low values for about 9 weeks after mating. The estrus return after paturtion indicated by a raise of fecal progesterone peak was 20 days since the doe did not nurse har baby. The above data indicated the validate fecal steroid endocrinal procedures for the Collared Anteater. |
