中文摘要 | 本試驗應用非侵入型法,藉由測定其糞孕酮(Fecal Progesterone)濃度變化及生殖 行為的觀察,了解臺灣黑熊(Selenarctos thibelanus for mosanus)之生殖狀態。試驗選用臺北 市立動物園中健康情形良好之雌黑熊3頭,自1990年3月至1992年7月,每週採糞 2~3 次,糞樣經有機溶劑萃取後以酵素免疫法分析測定孕酮含量。結果顯示未受公熊交配行為 刺激的1號熊糞孕酮濃度均維持在低濃度水平(37.5±9ng╱g),而受公熊交配的2號熊, 其濃度則有上升的變化三號熊亦如同二號熊,有孕酮濃度上升的變化,似有接受公熊的交 配,但未觀察到。由此推測臺灣黑熊可能具有誘發排卵(Induced Ovulation)與延遲埋植 (Delayed Implantation)的生殖現象。 |
英文摘要 | In this study, three adult female formosan black bears were used for examined their reproductive status by means of behavion observation and fecal progesterone monitoring. Fecal progesterone concentration were determined by using enzyme immunoassay from serial samples taken from animals 2-3 times per week over 1 to 2 year periods (3,1990-7,1992). Bear 1, not mated, showed a low level of fecal progesterone during 1 year experiment, with a baseline between 20-80ng/g (37.5+9ng/g, mean+s.d.). Bear 2, mated on 30 July, 1990, had a high level pattern of fecal progesterone concentrations during 12, 1991-1, 1992. Bear 3 exhibited the same pattern like bear 2, but was not observed to be mated during the 2 year experimental period. Therefore, from the fecal aboue findings, we may suggest that the female formosan black bears may process a peculiar reproductive status characterized induced ovulation and delayed implantation, like that in other bear species. A further study is needed for this postulate. |
