摘要 过去 20 年来，全球定位系统 (GPS) 项圈极大地促进了牲畜放牧行为的研究。现在可以通过 GPS 跟踪来准确且经济高效地监控旨在改善牲畜放牧分布的做法。例如，可以通过 GPS 跟踪来测量牛对远离水源和陡坡的饲料补充剂的使用情况，并估计对分布模式的相应影响。正在进行的研究已经确定了与牛空间运动模式相关的遗传标记。如果结果能够得到验证，放牧分布的遗传选择可能变得可行。跟踪项圈已经变得更容易开发和建造，使其成本大大降低，这可能会增加它们在牲畜放牧管理研究中的使用。可以设计一些研究问题，以便通过牲畜的空间运动来测量因变量，在这种情况下，GPS 跟踪是对广阔而崎岖的牧场进行研究的实用工具。同样，加速度计正在改变我们监测牲畜行为的能力。如今，加速度计非常灵敏，可以在几周到几个月的时间内以精细的时间尺度记录运动。 GPS 跟踪和加速计的结合似乎是识别与牲畜疾病和其他福利问题相关的牲畜行为变化的有用工具。最近的技术进步可能使牧场上的实时或近实时跟踪变得可行且具有成本效益。这将允许开发可以远程监控广阔牧场上牲畜健康的应用程序，并在动物需要治疗或其他管理时通知牧场主。
Abstract Over the last 20 yr, global positioning system (GPS) collars have greatly enhanced livestock grazing behavior research. Practices designed to improve livestock grazing distribution can now be accurately and cost effectively monitored with GPS tracking. For example, cattle use of feed supplement placed in areas far from water and on steep slopes can be measured with GPS tracking and corresponding impacts on distribution patterns estimated. Ongoing research has identified genetic markers that are associated with cattle spatial movement patterns. If the results can be validated, genetic selection for grazing distribution may become feasible. Tracking collars have become easier to develop and construct, making them significantly less expensive, which will likely increase their use in livestock grazing management research. Some research questions can be designed so that dependent variables are measured by spatial movements of livestock, and in such cases, GPS tracking is a practical tool for conducting studies on extensive and rugged rangeland pastures. Similarly, accelerometers are changing our ability to monitor livestock behavior. Today, accelerometers are sensitive and can record movements at fine temporal scales for periods of weeks to months. The combination of GPS tracking and accelerometers appears to be useful tools for identifying changes in livestock behavior that are associated with livestock diseases and other welfare concerns. Recent technological advancements may make real-time or near real-time tracking on rangelands feasible and cost-effective. This would allow development of applications that could remotely monitor livestock well-being on extensive rangeland and notify ranchers when animals require treatment or other management.
