Welfare outcome indicators measured at herd level provide more reliable information about animal experience than resource-based audits. Their integration into supply chain reporting is growing.
Herd-level welfare assessment reveals patterns invisible to individual animal examination — a farm where 25% of cows are lame has a systemic problem that individual audits may miss. Aggregated welfare outcome data from slaughter plants, combined with herd-level scoring from on-farm audits, provides a comprehensive picture of welfare performance. Making this data available to retailers and consumers creates market incentives for welfare improvement without requiring specific regulatory mandates.
