Horse breeding decisions significantly affect welfare of both mares and foals. Understanding responsible practices helps ensure breeding contributes to horse wellbeing.
Horse breeding welfare encompasses the reproductive experience of breeding animals, the health outcomes for foals, and the broader consequences for equine populations. Mares used intensively for breeding may face reproductive stress from frequent pregnancies and early post-partum breeding. Selective pressure for extreme athletic traits — speed, flexibility, size — can produce horses whose conformational extremes cause chronic soundness problems. The growing recognition that heritable conditions including PSSM, HYPP, and navicular disease have genetic components makes breeding decisions a welfare responsibility. The surplus of horses in many countries — whose rehabilitation falls on welfare organisations — reflects irresponsible breeding decisions by those who bred without ensuring good homes for the offspring they produced.
