- Phosphorus: 0.15–0.3%
- Ca:P Ratio: ~1.5–2:1 – Ideal for adult horses
Source: Feedipedia – Timothy Hay Profile

Palatability: High. Soft texture, low dust, sweet-smelling — most horses enjoy it.
Best For:
✅ Adult horses in light/moderate work
✅ Metabolic horses (IR, PPID, laminitis)
✅ Horses with respiratory sensitivity
✅ Easy keepers
Downsides:
⚠️ Lower energy; may not meet demands of lactating or high-performance horses
⚠️ Higher cost in non-growing regions
Cutting Notes:
- 1st Cutting: Coarse, mature, economical – lower in digestibility
- 2nd Cutting: Ideal balance – leafy, nutrient-rich, highly palatable
- 3rd Cutting: Softest, highest in calories – best for hard keepers or seniors
🟨 Bermuda Hay for Horses: Affordable, Fiber-Rich
Nutritional Profile (Typical, % of Dry Matter):
- Crude Protein: 7–12%
- ADF: 30–38%
- NDF: 55–65%
- Calcium: 0.3–0.6%
- Phosphorus: 0.2–0.4%
- Ca:P Ratio: ~1.5–2:1
Source: New Mexico State University – Circular 711: Selecting Forage for Horses

Palatability: Highly variable. Finer-stemmed hay harvested early is well-accepted. Mature or stemmy cuts can be refused.
Best For:
✅ Maintenance horses
✅ Easy keepers
✅ Budget-conscious barns in Southern U.S.
✅ Metabolic horses, if NSC is tested and verified low
Downsides:
⚠️ Impaction colic risk if hay is coarse and hydration is poor
⚠️ Blister beetles not typically a Bermuda risk (they’re associated with alfalfa in the Southwest)
⚠️ Variable nutrition; testing is recommended
Regional Insight:
Southern-bred horses are often more accustomed to Bermuda. Horses from northern or midwestern states may be slower to accept it due to differences in forage exposure.
🟪 Alfalfa Hay for Horses: High-Protein Forage
Nutritional Profile (Typical, % of Dry Matter):
Source: University of Minnesota Extension
- Crude Protein: 15–22% – Crucial for growth, recovery, lactation
- ADF: 25–30% – Highly digestible
- NDF: 40–50% – Still adequate for fiber needs
- Calcium: 1.0–1.5%
- Phosphorus: 0.2–0.3%
- Ca:P Ratio: ~5–7:1 – Must be balanced in the total diet

Palatability: Extremely high. Rich, leafy, sweet-smelling — even picky eaters consume it readily.
Best For:
✅ Foals and yearlings
✅ Lactating mares
✅ Performance horses in intense work (like racehorses post-training)
✅ Ulcer-prone horses (buffers stomach acid)
✅ Underweight or older horses needing condition
Downsides:
⚠️ Too rich for easy keepers
⚠️ Requires Ca:P balancing via grain, ration balancers, or grass hay
⚠️ Higher cost, especially outside production areas
Balancing Tip: Mix with grass hay (Timothy, Orchard), or add phosphorus-rich feed. UC Davis offers more tips on feeding Alfalfa.

❓ FAQs
Below are answers to some of the most common questions horse owners ask about hay types, feeding strategies, and how to meet the specific needs of different horses.
Can I feed only Alfalfa to my senior horse?
Yes, in moderation. Alfalfa supports weight and helps buffer stomach acid, but its high calcium needs to be balanced with phosphorus from other feeds or supplements. Always consult your vet before making major dietary changes. Best Senior Horse Feeds
What’s the most common hay-related mistake owners make?
Not testing hay. Nutrient levels—especially NSC, protein, and minerals—can vary significantly, even between cuttings from the same field. Best Practices for Feeding Hay
What is the best hay for a laminitic or insulin-resistant horse?
Low-NSC (<10%) Timothy or tested Bermuda hay. Avoid Alfalfa unless under veterinary direction, as it’s higher in sugar and protein. OPTIMIZING DIFFERENT HAY TYPES FOR HORSES
How do I know which hay cutting I have?
