Hay & Nutritional Needs: Why One Size Doesn’t Fit All 🌾🐴
Not all hay is created equal — and not all horses have the same dietary needs. Two big examples:
1️⃣ Horses with Equine Metabolic Syndrome (EMS)
For EMS horses, controlling sugar intake is critical to help prevent laminitis and manage insulin regulation. The key number to watch? NSC (Non-Structural Carbohydrates).
-Aim for NSC under 10% to reduce sugar/starch spikes.
-A hay analysis will tell you exactly where your forage falls — looks alone can’t reveal NSC content.
2️⃣ Growing Horses & Young Stock
Young horses have higher mineral demands, especially for bone development. One of the most important ratios to watch is calcium:phosphorus:
• Adult horses: Around 2:1 is ideal.
• Young stock: Can safely go up to 6:1, as long as the minimum phosphorus requirement is met. Too much calcium without adequate phosphorus can cause developmental issues — balance is key!
Takeaway:
The same bale of hay might be perfect for one horse and problematic for another. That’s why forage testing is one of the smartest investments you can make in your horse’s long-term health.
📋 Pro tip: Pair your hay analysis with your horse’s age, workload, and health status to build a feeding plan that truly fits their needs.
