Horse Welfare in Breeding: Conformation, Health and Longevity

Selective breeding for extreme conformations in some horse breeds causes welfare problems analogous to those in companion animal breeds, requiring evidence-based breeding reform.

Key Facts

Warmblood breeding for sport has produced horses with increased musculoskeletal problems in some lines
Arabian horse inbreeding has resulted in juvenile idiopathic epilepsy and other heritable conditions
Paint and Quarter Horses carry genetic risks including hyperkalemic periodic paralysis from sire line overuse
The value of performance bloodlines creates pressure to breed from horses with heritable health conditions
Veterinary assessment tools including radiographic screening enable health-based breeding selection
The Weatherby's racing register and similar bodies are beginning to incorporate health data in registration requirements

Welfare Considerations

Horse breed health is an underappreciated welfare issue compared to companion animal breed health reform. The commercial value of certain bloodlines creates strong economic incentives to breed from horses with known heritable conditions, prioritising performance or conformation over health. Evidence-based breeding reform that incorporates health screening and penalises heritable disease propagation is well-established in principle but incompletely implemented across equestrian disciplines. Breed registries and discipline governing bodies have important roles in creating the right incentive structures.

What You Can Do

Support breed registries that incorporate health screening in registration requirements
Avoid purchasing horses from bloodlines with known heritable health conditions
Advocate for veterinary health assessment requirements before approved breeding status
Support discipline governing bodies that prioritise horse health in breeding standard development
Share information about heritable equine health conditions with breeders and buyers
