由于动物通过行为表达其内部状态，因此所述行为的变化可用于检测问题的早期迹象，例如动物健康。在商业环境中，农场工作人员对牲畜进行持续观察，以发现与早期干预有关的行为变化，是不切实际的。开发了一种自动化监测系统;它使用深度摄像机自动跟踪猪的运动，并从3D轨迹自动测量站立、进食、饮水和运动活动。站立，进食和饮水的预测进行了验证，但没有自发活动。一种人为的、破坏性的挑战;即，引入新的对象，用于引起可再现的行为变化，以使得能够开发自动检测变化的系统。自动化监测系统的验证与控制挑战研究提供了一个可重复的框架，为进一步发展强大的早期预警系统的猪。该自动化系统在商业环境中是实用的，因为它提供了对多种行为的连续监测，其行为度量可以被认为是更直观的并且具有诊断有效性。该方法有可能改变牲畜的监测方式，直接影响它们的健康和福利，并解决畜牧业中的问题，如抗菌剂的使用。
Since animals express their internal state through behaviour, changes in said behaviour may be used to detect early signs of problems, such as in animal health. Continuous observation of livestock by farm staff is impractical in a commercial setting to the degree required to detect behavioural changes relevant for early intervention. An automated monitoring system is developed; it automatically tracks pig movement with depth video cameras, and automatically measures standing, feeding, drinking, and locomotor activities from 3D trajectories. Predictions of standing, feeding, and drinking were validated, but not locomotor activities. An artificial, disruptive challenge; i.e., introduction of a novel object, is used to cause reproducible behavioural changes to enable development of a system to detect the changes automatically. Validation of the automated monitoring system with the controlled challenge study provides a reproducible framework for further development of robust early warning systems for pigs. The automated system is practical in commercial settings because it provides continuous monitoring of multiple behaviours, with metrics of behaviours that may be considered more intuitive and have diagnostic validity. The method has the potential to transform how livestock are monitored, directly impact their health and welfare, and address issues in livestock farming, such as antimicrobial use.
