We evaluated impact of the needle length, sex, and body condition on chemical immobilization induction time in 50 (29 males and 21 females) free-ranging fallow deer (Dama dama) in Sweden, 2006-11. Induction time is probably the single most important factor when immobilizing free-ranging wildlife with the use of a remote drug-delivery system. Induction times should be short to minimize stress and risk of injury, and to ensure that immobilized animals can be found and clinically monitored as soon as possible. We measured the distance between the darting location and where we recovered the immobilized animal and also the time occurring between the two events. We used two types of needles: 2.0 × 30- or 2.0 × 40-mm barbed needles with side ports. The most important result is that a 10-mm-longer dart needle can reduce the retrieval time substantially (>20 min) until an animal is under monitoring. On average after the darting, the retrieval time decreased from 51 to 29 min and the distance decreased from 519 m from the darting location to 294 m. We suggest that a needle length of 40 mm is preferable for immobilization of wild fallow deer, especially for animals in over-average-to-fat body condition.
2006年至2011年期间，我们在瑞典对50只（29只雄性和21只雌性）自由放养的黇鹿（黇鹿属）进行了评估，以研究针长、性别和身体状况对化学保定诱导时间的影响。在使用远程给药系统对自由放养的野生动物进行保定操作时，诱导时间可能是最重要的单一因素。诱导时间应尽量短，以将应激和受伤风险降至最低，并确保能尽快找到被保定的动物并对其进行临床监测。我们测量了注射地点与找回被保定动物地点之间的距离，以及这两个事件之间的时间间隔。我们使用了两种类型的针：带侧孔的2.0×30毫米或2.0×40毫米有倒刺针。最重要的结果是，长10毫米的注射针可大幅缩短（超过20分钟）动物进入监测状态前的找回时间。平均而言，注射后，找回时间从51分钟降至29分钟，距离从距注射地点519米降至294米。我们建议，对于野生黇鹿的保定，40毫米的针长更可取，尤其是对于身体状况高于平均水平至肥胖的动物。
