New technologies including precision livestock farming, automated welfare monitoring, and wearable sensors are creating opportunities to detect and address welfare problems earlier and more accurately.
Precision livestock farming technology offers significant welfare benefits by detecting problems earlier and more consistently than human observation alone. Lameness detected by accelerometer in week two of developing is more treatable than lameness first noticed visually at week six. Fever detection through ear tags allows antibiotic treatment before disease becomes severe. Computer vision in poultry sheds can alert operators to abnormal clustering, reduced activity, or mortality that would otherwise go undetected overnight. These technologies complement rather than replace skilled stockpeople, and their welfare value depends on acting on the data they generate.
