Precision livestock farming (PLF) uses sensors, cameras, and algorithms to monitor individual animal health and behavior. These technologies have significant potential to improve welfare through earlier detection of problems.
Precision livestock farming represents one of the most significant technological opportunities for farm animal welfare improvement. The fundamental welfare benefit is simple: earlier detection of individual animal health problems allows earlier treatment, reducing the duration and often the severity of suffering. A cow whose mastitis is detected 12 hours earlier receives treatment 12 hours sooner; a lame pig identified before lameness becomes severe can be treated before significant pain accumulates. PLF systems that provide this kind of individual monitoring at commercial scale, previously requiring impossible levels of human observation, are genuine welfare tools. The challenge is ensuring they supplement rather than replace attentive stockmanship.
