Standardized welfare metrics allow systematic comparison of pig welfare across farms, enabling evidence-based improvement and transparent consumer information.
Standardized welfare metrics transform welfare from an abstract aspiration to a measurable outcome. When farms know they will be assessed against specific behavioral and health indicators, the accountability creates pressure toward genuine improvement. Outcome-based metrics like lameness prevalence and social injury rates reflect actual animal experience rather than just physical housing standards. Combining farm-level assessment with supply chain transparency enables consumers and retailers to make welfare-based purchasing decisions.
