Introduction
Feeding horses with natural, additive-free ingredients promotes optimal health, digestion, and performance. Unlike processed feeds, whole foods provide essential nutrients without artificial preservatives or fillers. This guide offers evidence-based recommendations for equine nutrition.
Recommended Diet Types
Horses are herbivores with hindgut fermentation. Their diet should be high in fiber and low in sugar/starch.
- Hay and Pasture: The foundation. Timothy, orchard grass, or bermudagrass hay. Pasture grass provides vitamins and exercise.
- Whole Grains: Oats, barley, or corn — only for horses with high energy demands. Soaking reduces dust.
- Vegetables: Carrots, apples, and beet pulp (soaked) as treats or supplements.
- Supplements: Flaxseed or chia for omega-3s; salt for electrolytes.
Food Portions and Daily Caloric Needs
Calorie requirements vary by weight, age, and workload. Use the table below as a guide.
| Weight (kg) | Workload | Hay (kg/day) | Grain (kg/day) | Calories (Mcal/day) |
|---|---|---|---|---|
| 450 (dry) | None | 9-11 | 0 | 16.5 |
| 450 (light) | Light | 9-11 | 1.4 | 20 |
| 500 (moderate) | Moderate | 10-12 | 2.7 | 25 |
| 550 (intense) | Intense | 10-12 | 4.5 | 33 |
Always adjust based on body condition score (BCS). Young, growing horses need more protein and energy; seniors may require easier-to-chew forages.
Feeding Frequency and Schedule
Horses are grazing animals and should eat frequently. Provide free-choice hay or at least 3-4 meals daily. Wait 30-60 minutes after exercise before feeding grain to prevent colic. Consistency in timing reduces stress.
Essential Nutrients
- Protein: 10-14% of diet. Forage provides sufficient protein for most horses; legumes (alfalfa) are higher.
- Fats: Omega-3s from flaxseed or fish oil support coat and joint health. Limit to 8% of diet.
- Carbohydrates: Fiber (hay) is crucial. Simple sugars should be minimal to avoid laminitis.
- Vitamins and Minerals: Balancing calcium, phosphorus, and trace minerals (copper, zinc, selenium) is key. Feed a ration balancer if needed.
Foods and Ingredients to Avoid
Many human foods are toxic to horses:
- Avocado: Persin causes respiratory distress.
- Chocolate/caffeine: Theobromine toxic.
- Laurel, rhododendron: Cardiac toxins.
- Stale/ moldy feed: Risk of colic and mycotoxins.
- Too much grain: Can cause laminitis or colic.
- Fruit seeds/pits: Contain cyanide (e.g., apple seeds).
Water Intake
Horses need 25-55 liters (6-14 gallons) daily, more in heat or with exercise. Provide fresh, clean water at all times. Increase salt intake (1-2 tbsp/day) to encourage drinking.
Beneficial Supplements
While whole foods are ideal, certain additives help:
- Electrolytes: For heavy sweating (e.g., endurance rides).
- Probiotics: Support hindgut health after antibiotics or stress.
- Vitamin E + Selenium: Antioxidants for muscle function.
- Joint supplements: Glucosamine, chondroitin, or MSM for older horses.
Feeding Differences by Age
Foals (0-6 months)
Milk first, then creep feed (18-20% protein). Introduce small amounts of hay.
Weanlings/Yearlings (6-18 months)
High-quality forage and a balanced growth feed (14-16% protein) to support skeletal development.
Adult (4-15 years)
Maintenance diet with pasture/hay and work-adjusted grains. Monitor BCS.
Senior (15+ years)
Easy-to-chew fiber (soaked cubes, pellets). Lower starch. Add fat for calories. Regular dental exams.
Signs of Healthy vs. Poor Diet
Healthy: Shiny coat, bright eyes, consistent manure, ideal BCS (5-6), good energy.
Poor diet: Dull coat, weight loss/gain, lethargy, soft or hard manure, laminitis symptoms (reluctance to move), colic episodes.
Conclusion
Feeding natural, additive-free ingredients aligns with equine biology. Prioritize quality forage, balance nutrients, and adjust for individual needs. Always consult a veterinarian or equine nutritionist for personalized plans.
