Outcome-based welfare assessment systems that measure animal-based indicators — lameness, body condition, injuries, and behaviour — provide more accurate welfare information than input-based audits alone.
Outcome-based welfare assessment represents a paradigm shift in how farm animal welfare is evaluated. Traditional audits assess whether farms have the right facilities and inputs — but a farm can have compliant housing and still have 25% lame cows. Animal-based measures cut through this gap by measuring what actually matters: are these animals experiencing pain, fear, and deprivation? Lameness scoring that reveals 20% prevalence identifies a welfare problem requiring intervention regardless of housing type. Body condition scoring below 2.5 at calving indicates nutritional failure. Avoidance distance above 100cm indicates fear of humans that reflects poor stockperson-animal relationships. These measures empower farmers, vets, and auditors to identify and act on real welfare problems rather than paper compliance.
