中文摘要 | 圈養在臺灣南部,出生日期分佈在1個月內之年輕雌性臺灣梅花鹿5頭,自離乳起至呈現首次配種接受性為止,每月1次被收集活體重與體型相關之體尺值,提供為探討雌鹿迄發身階段體型之發育用。試驗之全期間均予任飼,並於其13月齡,同群鹿隻將進入配種季節前被與雄鹿分離,同時每日2次,每次至少30分鐘,普分別於上、下午以具有生育行為能力之成年雄鹿測試其配種接受性。結果顯示,鹿隻離乳時之活體重值(Avg, 15.1 kg)與各項體尺丈量值間,以及離乳體重與發身月齡(Avg. 16月齡)和發生體重(Avg. 40.5 kg)間均未具顯著相關性(P>0.05),惟發身時活體較重者,其胸圍、頸圍和以胴體長值亦顯著較大(P<0.05)。自13月齡起,試驗鹿隻之胸唔三、胴體長、臀長、臀寬和坐骨寬隨月齡增加之增長趨勢均較活體重者迅速,其骨盤腔背平面面積值之增長與活體重考呈現相反之趨勢,並與月齡之增加密切同(P<0.05)。綜合本研究之結果顯示,雌性臺灣梅花鹿於鄰近發身階段之發育趨勢以與體腔和骨盤腔容積相關體尺之增長較活體重者為優勢。 |
英文摘要 | Live body weight (LBW) and measurements of body conformation (MBC) from weaning to the 1st sexual acceptance in 5 juvenile Formosan sika deer hinds fed ad libitum were collected once monthly for the investigation of development of body conformation associated with puberty. They were kept off the male mates at beginning of the rutting season in 13 mo of age. Thereafter sexual acceptance of the hinds was twice daily checked at least 30 min at 0700 and 173.0 by a fertile stag. Results showed that although all of the MBC values at weaning stage, the age at puberty (Avg. 16mo) and the LBW at puberty (Avg. 40.5kg) were not significantly affect (P>0.05) by the weaning weight (Avg. 15.1 kg), the LBW was closed related to the measurements of heart girth, neck girth and trunk length (P<0.05) at puberty stage. The heart girth, trunk length, rump length, rump width, pin bone width and dorsal plane of the pelvic cavity developed promptly since the 13 mo of age to the age at puberty in spite of the increment of LBW was kept steadily. It is concluded that a dominant trending of the region governing development of the body and pelvic cavity in the juvenile Formosan sika deer hinds at the stage of puberty. |
