New technologies including camera-based lameness detection, acoustic monitoring for respiratory disease, and machine learning welfare scoring systems allow earlier detection of health problems in commercial poultry, reducing the welfare burden of disease.
Lame broilers that are not detected promptly continue to experience pain without treatment for days. Respiratory disease that progresses without early detection causes pneumonia and associated systemic illness. The welfare benefit of early detection technologies lies in the time between welfare problem onset and intervention, which determines the total welfare burden experienced by affected birds. Technology that halves detection time halves the average welfare burden of each episode.
