Summary
# Editorial Summary Comprehensive welfare assessment in horses demands that professionals first establish robust baseline knowledge of normal equine physiology, behaviour and environmental needs under optimal conditions—a foundation often assumed rather than explicitly addressed in practice. Harvey, Ramp and Mellor's 2022 review systematically consolidates species-specific knowledge across four objective domains: nutrition, physical environment, health, and behavioural interactions, providing a structured framework derived from the Five Domains Model that allows practitioners to systematically evaluate each functional area before making inferences about psychological welfare states. By anchoring assessment methodology in detailed understanding of natural free-roaming horse behaviour and physiology, the authors demonstrate how human interventions in domestic settings can be properly contextualised and their welfare impacts accurately judged against what is biologically normal for the species. For farriers, veterinarians, physiotherapists and other equine professionals, this synthesis emphasises that meaningful welfare evaluation requires interdisciplinary knowledge—nutritional adequacy cannot be assessed without understanding physical environmental demands, and behavioural abnormalities cannot be interpreted without solid grounding in health status and metabolic function. The practical value lies in moving welfare assessment beyond anecdotal observation towards a systematic, evidence-based approach that identifies which specific domains may be compromised in individual horses or management systems.

Practical Takeaways
- •Use the Five Domains Model systematically when evaluating any horse's welfare—start with objective assessment of nutrition, environment, health, and behavior before considering mental state
- •Build your knowledge of what 'normal' looks like in free-roaming horses to better recognize welfare problems in domestic situations
- •Comprehensive welfare assessment requires multidisciplinary input; don't rely on a single assessment method or professional perspective
Key Findings
- •The Five Domains Model provides a structured framework for comprehensive horse welfare assessment across nutrition, physical environment, health, and behavioral interactions
- •Species-specific foundational knowledge of normal horse physiology and behavior under optimal conditions is essential for identifying welfare-relevant deviations
- •Understanding free-roaming horse biology and behavior provides critical baseline data for evaluating welfare impacts of human intervention and domestication
- •Domains 1-4 (physical/functional) must be thoroughly assessed before making inferences about Domain 5 (mental state) in welfare evaluations
