Developmental Orthopedic Disease in Young Horses

Conditions like osteochondrosis affect growing horses, causing joint pain and lameness. Management of young horses' diet and exercise is critical to prevention.

Key Facts

Osteochondrosis affects up to 25% of horses in some breed populations
Rapid growth, high-energy diets, and mineral imbalances contribute to development
OCD lesions can cause significant joint pain and lameness in yearlings
Surgical intervention is required for some lesions but many resolve with rest
Warmblood sport horse breeds show particularly high prevalence

Welfare Considerations

Developmental orthopedic diseases cause young horses to begin life with painful joint conditions before they have ever been trained. The welfare cost of OCD includes painful cartilage lesions, joint effusion, and restricted movement during what should be a period of free exploration and play. Prevention through careful nutritional management - controlling growth rate, balancing calcium and phosphorus, and avoiding sugar and starch excesses - significantly reduces prevalence. Breeders selecting for rapid growth at the expense of skeletal maturity perpetuate a preventable welfare problem.

What You Can Do

Feed broodmares and growing foals balanced rations avoiding excessive energy and sugar
Have foals and yearlings assessed for joint effusion by a vet as part of routine health checks
Restrict fast growth through diet rather than relying on exercise to compensate
Ensure paddock turnout allows free movement but avoid forced exercise in growing horses
Select breeding stallions with low OCD prevalence in offspring data
