Summary
# Welfare Quality of Breeding Horses Under Different Housing Conditions Confined stallions experience substantially poorer welfare outcomes than extensively housed broodmares, according to this 2019 assessment of 330 tie-stall stallions and 365 free-housed mares using a comprehensive welfare protocol evaluating health, behavioural and locomotor parameters. Stallions demonstrated significantly higher prevalence of dyspnoea, tendon and joint swellings, abnormal gait and compromised hoof horn quality compared with mares, with median welfare scores placing stallions in the "acceptable" to "enhanced" range versus mares achieving "enhanced" to "excellent" classifications. Human-related behavioural responses—including handling reactivity—showed no significant difference between the two groups, suggesting that chronic confinement stress manifests primarily through physical health deterioration rather than overt behavioural abnormalities. The findings argue persuasively for transitioning tie-stall breeding operations towards free-housing systems incorporating individual boxes, a management shift that could substantially mitigate the musculoskeletal and respiratory consequences associated with prolonged restraint. For practitioners advising breeding facilities, this research provides evidence-based justification to recommend housing modifications as a welfare-enhancing intervention with tangible effects on soundness and long-term athletic viability of stallion offspring.

Practical Takeaways
- •Tie-stall housing for stallions correlates with higher rates of musculoskeletal and respiratory problems; consider transitioning to free-stall or box systems to reduce these health issues
- •Housing system choice significantly impacts breeding horse welfare; extensive free housing appears superior for overall welfare metrics compared to restrictive tie-stall systems
- •Behavioral adaptation to housing may not fully reflect underlying welfare problems—clinical health indicators (gait, hoof quality, swellings) are more discriminating welfare measures than behavior alone
Key Findings
- •Stallions in tie-stall housing had significantly higher prevalence of dyspnea, tendon/joint swellings, abnormal gait, and hoof horn quality issues compared to mares in extensive free housing (p < 0.05)
- •Broodmares achieved 'enhanced' and 'excellent' welfare scores while stallions achieved only 'acceptable' and 'enhanced' scores (p < 0.05 difference)
- •No significant differences in human-related behavioral responses were found between the two housing groups (p > 0.05)
- •Free housing with boxes could improve welfare quality of breeding stallions compared to tie-stall systems
