Precision livestock farming uses sensors, cameras, and AI to monitor individual animal welfare indicators in real time. In dairy systems, this technology is transforming early detection of health problems and welfare monitoring.
Precision livestock farming represents a genuine opportunity to scale welfare monitoring in ways impossible through human observation alone. A dairy herd of 500 cows cannot be individually observed continuously by farm staff, but sensor networks can monitor every individual in real time. When a cow stops ruminating at her normal rate, or her activity pattern changes, or her milk quality shifts, an alert can trigger immediate veterinary attention rather than waiting for the problem to become obvious. The welfare benefit depends entirely on what happens after the alert — technology that generates data nobody acts on provides no welfare benefit. The farms that achieve the most welfare improvement from PLF are those that pair the technology with trained staff empowered to respond and management cultures that prioritize welfare intervention.
