Breeding selection in horses shapes long-term welfare outcomes across populations — evidence shows that conformation extremes and breed-specific traits create predictable welfare burdens.
Breed welfare in horses is determined by the cumulative welfare consequences of selection decisions made over generations. Breeding for extreme traits — speed, suspension, size, facial conformation — consistently produces welfare trade-offs that individual horses bear throughout their lives. The equine welfare community increasingly advocates for breeding welfare outcome data collection and transparency, including soundness longevity, lameness prevalence, and veterinary intervention rates, as part of breed registration and competition scoring.
