Buying Guide: Key Considerations For Ulcer-Prone Horses
- Forage-first feeding: Prioritize high-quality hay and/or grazing to support saliva production and stabilize stomach pH, reducing ulcer risk when possible.
- Starch and sugar management: Choose feeds with controlled starch levels and avoid highly processed concentrates that spike gastric acid production.
- Gastric buffering ingredients: Look for calcium-based buffering, magnesium, and ingredients that promote a stable gastric environment, such as seaweed-derived minerals or buffering agents.
- Omega-3 fatty acids: Incorporate sources of Omega-3s for anti-inflammatory benefits and coat health, which can support overall well-being in ulcer-prone horses.
- Amino acids and gut integrity: Supplements containing L-glutamine, L-threonine, and similar amino acids may help maintain intestinal lining and digestion under stress.
- Senior considerations: Aging horses often benefit from high-fiber, high-fat feeds with easily digestible ingredients and joint support—while still focusing on gut comfort.
- Feeding schedule: Smaller, more frequent meals can help buffer stomach acid and reduce ulcer flare-ups compared to infrequent large meals.
- Monitoring and adjustment: Track weight, coat condition, stool quality, and appetite, adjusting feed types and amounts as needed under veterinary guidance.
- Veterinary coordination: Work with a veterinarian or equine nutritionist to tailor a plan that aligns with a horse’s ulcer status, stabling, exercise, and overall health goals.
- Notes on product labeling: Some items are designed as supplements or senior feeds rather than ulcer cures; use them within a comprehensive ulcer-management plan.
