As wild pigs (Sus scrofa) expand throughout North America researchers are increasingly being tasked with trapping and marking entire sounders (family groups) to attach monitoring devices or other identifying markers to gather knowledge to inform management. Capture and marking procedures can be challenging, dangerous for both researchers and animals, and time consuming, particularly when handling sounders. We developed an integrated pig‐handling system to efficiently sort, weigh, chemically immobilize, and mark multiple wild pigs simultaneously in a controlled manner. To assess the functionality of the system, we evaluated 18 capture events in Texas, USA, from January 2018 to March 2019, where we marked 221 pigs of varied age classes and group sizes (2–19 animals). Using the pig‐handling system, we chemically immobilized 51 large (41–101 kg) pigs and manually restrained 170 smaller (<45 kg) pigs with injury rates below 4%. Average handling times for large pigs was 71.9 (SD = 25.7) min and <1 min for smaller ones. We released sounders intact and routinely recorded them together on motion‐activated cameras. Incorporating a handling system into wild pig research and management is encouraged to facilitate safe handling procedures for both pigs and handlers. © 2021 The Wildlife Society.

处理野生猪整个发声器的改进策略

作为野猪(Sus scrofa)扩展到整个北美地区,研究人员的任务越来越多,即捕获和标记整个发声器(家庭组)以连接监视设备或其他识别标记,以收集知识以告知管理人员。捕获和标记程序可能具有挑战性,对研究人员和动物都非常危险,并且非常耗时,尤其是在处理发声器时。我们开发了一个集成的生猪处理系统,以可控方式同时有效地分拣,称重,化学固定和标记多头野猪。为了评估系统的功能,我们评估了2018年1月至2019年3月在美国得克萨斯州进行的18次捕获事件,在那里我们标记了221头不同年龄级别和组大小的猪(2-19只动物)。使用生猪处理系统,我们化学固定了51头大猪(41-101千克),并手动约束了170头小猪(<45千克),受伤率低于4%。大型猪的平均处理时间为71.9分钟(标准差= 25.7)分钟,小型猪的平均处理时间小于1分钟。我们完整地释放了发声器,并定期将它们记录在运动激活的摄像机上。鼓励将处理系统纳入野猪的研究和管理中,以促进猪和处理者的安全处理程序。©2021野生动物协会。本文是美国政府的工作,在美国属于公共领域。鼓励将处理系统纳入野猪的研究和管理中,以促进猪和处理者的安全处理程序。©2021野生动物协会。本文是美国政府的工作,在美国属于公共领域。鼓励将处理系统纳入野猪的研究和管理中,以促进猪和处理者的安全处理程序。©2021野生动物协会。本文是美国政府的工作,在美国属于公共领域。
