Artificial intelligence and sensor technologies are transforming the ability to monitor individual animal welfare at scale on commercial farms. Understanding these tools helps evaluate their welfare potential.
Precision livestock farming technologies offer genuine welfare benefits: earlier disease detection reduces the duration of untreated suffering; individual monitoring identifies animals that are not thriving before their condition deteriorates; data-driven management reduces unnecessary interventions while targeting necessary ones. However, technology alone does not improve welfare - it must be combined with motivated stockpeople who act on the data and the resource and knowledge to intervene effectively. Technology as a substitute for human stockpersonship attention is a welfare risk.
