Nutritional Value of Good-Quality Horse Hay
1. Fiber Content
Primary nutrient in hay; supports healthy gut motility and microbial balance.
Horses require long-stem fiber to reduce the risk of colic and maintain digestive health.
2. Protein
Grass hays (Timothy, Orchardgrass, 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
