The Ultimate Guide to Equine Nutrition: What Every Owner Should Know

Proper equine nutrition is the foundation of a healthy, happy, and high-performing horse. Whether you own a competition horse, a leisure pony, or a retired companion, understanding their dietary needs is essential. In this guide, we’ll break down everything you need to know about feeding your horse the right way.

 

1. Understanding the Basics of Equine Digestion

Horses are herbivores with a unique digestive system designed for continuous grazing. Unlike humans, they have a small stomach and rely on a hindgut fermentation process to break down fibrous food. This means:

  • They should eat small, frequent meals rather than large ones.
  • Their diet should be high in fiber to maintain gut health.
  • Sudden changes in feed can cause colic or digestive upset.

📌 Real-world example: Horses that are fed large grain meals once or twice a day, instead of having constant access to forage, are at higher risk of gastric ulcers and colic.

2. Forage: The Foundation of Every Horse’s Diet

Forage, including hay, haylage, and grass, should make up at least 70-80% of a horse’s diet. Good-quality forage ensures gut health, provides essential nutrients, and keeps your horse mentally satisfied.

Types of Forage:

  • Grass – Natural and ideal for most horses but monitor for lush spring grass, which can cause laminitis.
  • Hay – Dry forage, perfect for winter feeding or stabled horses.
  • Haylage – More moisture than hay, often richer in nutrients.

📌 Real-world example: A horse on full turnout will get most of its nutrition from pasture, whereas a stabled performance horse will need supplemented hay and concentrates.

3. Concentrates: When Does Your Horse Need Them?

Not all horses need concentrated feeds (grains, pellets, or mixes). These are typically used for horses with higher energy demands, such as competition horses or breeding mares.

Types of Concentrates:

  • Cubes/Pellets – Compact and balanced, great for easy feeding.
  • Mixes – Loose blends of grains and other ingredients.
  • High-Fibre Feeds – Ideal for older horses or those with metabolic issues.

📌 Example: A racehorse in full training might require a high-calorie mix with added electrolytes, whereas a retired pony would thrive on forage alone.

4. Vitamins & Minerals: Essential for Optimal Health

Even with a good diet, some horses need extra vitamins and minerals, especially if they have restricted grazing or are fed mainly on hay.

Key Nutrients:

  • Calcium & Phosphorus – For strong bones.
  • Magnesium – Helps with muscle function and relaxation.
  • Biotin – Supports healthy hooves and coat.
  • Electrolytes – Essential for working horses to replace lost salts.

📌 Example: Horses on a hay-only diet may need a broad-spectrum vitamin and mineral supplement to make up for lost nutrients found in fresh grass.

5. Hydration: The Key to a Healthy Horse

A horse can drink 25-55 litres of water per day, depending on weather and workload. Dehydration can lead to colic and poor performance.

Signs of Dehydration:

  • Lethargy
  • Dry gums
  • Reduced skin elasticity (skin pinch test)

📌 Example: Horses in work, especially during summer, may benefit from electrolyte supplements to encourage water intake.

6. Feeding Different Types of Horses

Each horse has unique dietary requirements based on age, workload, and health status.

Example Diets:

  • Leisure Horse: Good-quality forage, salt lick, and balancer if needed.
  • Performance Horse: Forage + high-energy concentrates + electrolytes.
  • Senior Horse: Softened hay/haylage, senior-specific feeds, joint supplements.

📌 Real-world example: An endurance horse needs high-fat, high-fiber diets to sustain energy, whereas a Shetland pony prone to laminitis requires a low-calorie, high-fiber diet.

7. Common Feeding Mistakes to Avoid

🚫 Overfeeding grains – Can lead to colic or laminitis. 🚫 Feeding too little forage – Can cause ulcers and boredom. 🚫 Not balancing the diet – Missing key vitamins/minerals. 🚫 Sudden diet changes – Always introduce new feeds gradually.

📌 Example: A sudden switch from hay to lush pasture in spring can trigger laminitis in ponies, making gradual transition essential.

Conclusion: Feed Smart for a Healthy Horse

Providing the right nutrition for your horse is one of the most important responsibilities as an owner. Remember:

Prioritize forage over concentrates.

Ensure a balanced diet with necessary vitamins/minerals.

Provide constant access to fresh water.

Adjust feeding plans based on age, workload, and health.

 

By following these guidelines, you can ensure your horse stays in peak condition, whether they are a happy hacker, a high-performance athlete, or a golden oldie enjoying retirement.
