Effective pig welfare auditing requires validated protocols, trained auditors, and follow-up mechanisms that create genuine accountability for welfare outcomes.
Welfare auditing that relies primarily on resource and procedure checks can miss poor welfare outcomes that occur despite apparently adequate inputs. Animal-based outcome measures including lameness prevalence, injury rates, and behavioural indicators provide more sensitive detection of welfare problems. Regular auditing with honest feedback and action planning creates a continuous improvement cycle. The rigour of auditing protocols determines how well they protect pig welfare in practice.
