Tail biting in pigs is a serious and unpredictable animal welfare problem for farmers worldwide. It results in losses forfarmers of £10.4M a year in the UK alone, mainly from carcass condemnation. Before damaging tail biting begins, pigs holdtheir tails down. This project will develop a system to detect these tail posture changes using a 3D video system givingfarmers advance warning of tail biting in time to intervene. We will 1) Collect continuous 3D video from pigs at a high risk oftail biting to capture the changes in tail posture pre-tail biting, 2) Provide a detailed behaviour analysis of tail posturechanges and 3) Develop software algorithms to automate this. The project partners provide expertise in pig behaviour(SRUC), a route to market and algorithms for automated 3D video analysis (Innovent Technology Ltd), pork supply chainknowledge (Sainsbury's) video expertise and access to a network of expertise in engineering and precision agriculture(Agri-EPI centre).

猪咬尾对全世界的农民来说是一个严重和不可预测的动物福利问题。仅在英国，每年就给农民造成1040万英镑的损失，主要来自屠宰场的没收。在开始咬尾巴之前，猪会把尾巴压低。该项目将开发一个系统，使用3D视频系统检测这些尾巴姿势的变化，使农民提前警告咬尾巴及时干预。我们将1）从高咬尾风险的猪身上收集连续的3D视频，以捕捉咬尾前尾部姿势的变化，2）提供尾部姿势变化的详细行为分析，3）开发软件算法来自动化。项目合作伙伴提供猪行为方面的专业知识（SRUC），自动化3D视频分析的市场路线和算法（Innovent Technology Ltd），猪肉供应链知识（Sainsbury's）视频专业知识以及工程和精准农业专业知识网络（Agri-EPI中心）。
