Welfare auditing on sheep farms provides the monitoring infrastructure that links certification standards to on-farm practice — with quality depending on audit design and frequency.
Sheep welfare auditing translates certification standards into on-farm practice through regular inspection. The effectiveness of auditing depends on audit frequency, the proportion of unannounced visits, the use of outcome-based measures rather than just resource-based checks, and the consequences for identified non-compliance. Current sheep assurance auditing in most countries is insufficient to guarantee welfare outcomes: low visit frequency, primarily announced visits, and weak consequences for violations all reduce effectiveness. Moving toward outcome-based, frequent, unannounced auditing would significantly improve the protective function of sheep welfare certification.
