- Grass hays (Timothy, Orchard grass, Fescue): typically, 8–12% crude protein.
- Legume hays (Alfalfa, Clover): higher protein, often 15–20%.
- Protein is vital for muscle development, tissue repair, and growth.
3. Energy (Digestible Energy, DE)
- Grass hays: ~0.76–0.94 Mcal/lb.
- Legume hays: ~0.94–1.19 Mcal/lb.
- Provides fuel for daily activity, performance, and maintenance.
4. Minerals
- Calcium & Phosphorus: Legume hays are rich in calcium, while grass hays have lower levels.
- Magnesium & Potassium: Present in moderate amounts, supporting nerve and muscle function.
- Trace minerals (Copper, Zinc, Manganese): vary depending on soil and growing conditions.
5. Vitamins
- Vitamin A (from carotene): abundant in fresh, leafy hay; supports vision and immunity.
- Vitamin D: formed when horses are exposed to sunlight, but hay contributes small amounts.
- Vitamin E: found in green hay, important for muscle and immune health
