Horse Feeding 101: How to Choose the Right Nutrition Plan

Feeding a horse isn’t as simple as tossing hay into a stall and calling it a day. Whether you’re new to horse ownership or refining your current approach, understanding horse feeding is essential to the long-term health, performance, and happiness of your equine companion. With so many feed options, supplements, and conflicting advice floating around, it’s easy to feel overwhelmed. That’s why we’ve created this comprehensive guide to help you build the right nutrition plan tailored to your horse’s unique needs.

Understanding the Basics of Horse Feeding

Before diving into feed charts and supplements, let’s cover the fundamentals of horse nutrition. Horses are non-ruminant herbivores, meaning they have a single-chambered stomach but rely heavily on fiber from forage (like grass and hay) to fuel their digestive systems. A horse’s digestive tract is designed for continuous grazing—up to 18 hours a day—making steady intake of fibrous material crucial.

Key components of a balanced diet:

• Forage (Hay and Pasture): The foundation of any horse’s diet. It should make up at least 50%–70% of total intake.
• Water: Clean, fresh water should be available at all times.
• Concentrates (Grains, Pellets): Often used for horses with higher energy requirements.
• Salt and Minerals: Needed in trace amounts for metabolic function.
• Supplements: Optional additions that can address specific health or performance needs.

Step 1: Know Your Horse’s Individual Needs

Every horse is different. Age, weight, activity level, breed, health status, and even personality can influence the best horse feeding approach. Start by evaluating the following:

• Age: Foals, adult horses, and seniors all have distinct nutritional requirements.
• Weight & Body Condition: Use a body condition scoring chart (1 to 9 scale) to assess whether your horse is underweight, overweight, or ideal.
• Activity Level: A retired pasture companion needs far fewer calories than a performance athlete.
• Health Conditions: Horses with issues like Cushing’s, insulin resistance, or ulcers require specialized diets.
• Breed Tendencies: Some breeds, like Arabians, are “easy keepers,” meaning they maintain weight easily, while Thoroughbreds often require higher caloric intake.

Step 2: Prioritize Forage Quality

Forage should be the cornerstone of any horse feeding plan. High-quality hay or pasture provides the necessary fiber for healthy gut function and delivers vital nutrients.

Types of Forage:

• Grass Hay (e.g., Timothy, Orchard): Lower in calories and protein; ideal for maintenance diets.
• Legume Hay (e.g., Alfalfa, Clover): Higher in protein and calcium; better for growing horses, lactating mares, or underweight animals.

Tips for Choosing Good Hay:

• Bright green color
• Pleasant smell (no musty or moldy odor)
• Free from dust and weeds
• Not too stemmy or coarse

How Much Forage?
Most horses should consume 1.5%–2.5% of their body weight in forage daily. A 1,000-pound horse typically eats around 15–25 pounds of hay or pasture per day.

Step 3: Use Concentrates Thoughtfully

Concentrates are feeds designed to boost calorie and nutrient intake beyond what forage provides. These are usually grain-based and come in sweet feeds, pellets, or textured blends.

When to Add Concentrates:

• Your horse is in hard work or training.
• Your horse struggles to maintain weight on forage alone.
• Your horse has specific nutritional deficiencies that forage can’t meet.

Caution:
Overfeeding grain can lead to colic, laminitis, or behavior issues. Introduce concentrates gradually and never feed large grain meals (over 5 pounds) at one time.

Step 4: Monitor Protein, Vitamins, and Minerals

Many horse owners worry about protein, but most adult horses in light work meet their needs through forage alone. However, certain life stages and workloads increase demand.

Protein Needs by Life Stage:

• Adult maintenance: 8–10%
• Light work: 10–11%
• Moderate to heavy work: 11–14%
• Growing horses and broodmares: up to 16%

Minerals like calcium, phosphorus, magnesium, and selenium are critical for bones, muscles, and overall metabolic function. A vitamin/mineral balancer or free-choice salt block can help fill nutritional gaps.

Step 5: Tailor to Special Cases

Some horses require custom plans due to medical or behavioral conditions. Here are a few examples:

• Senior Horses: May need easy-to-chew feeds, higher protein, and joint supplements.
• Easy Keepers: May thrive on hay and a ration balancer alone.
• Hard Keepers: Often benefit from added fat sources (e.g., rice bran, flaxseed).
• Horses with Insulin Resistance or Cushing’s: Require low-sugar, low-starch diets.

Consult your veterinarian or an equine nutritionist to design a diet that meets these special requirements.

Step 6: Establish a Consistent Routine

Horses thrive on consistency. Sudden changes in diet can upset the gut microbiome and cause digestive issues.

Feeding Routine Tips:

• Feed at the same times every day.
• Split meals into smaller, more frequent portions if possible.
• Make changes to feed or hay types gradually over 7–10 days.
• Always introduce new supplements one at a time so you can track effects.

Step 7: Don’t Forget Fresh Water and Salt

A horse can drink anywhere from 5 to 15 gallons of water per day depending on weather, activity, and diet. Dehydration can quickly become dangerous, leading to impaction colic and other health risks.

Encouraging Water Intake:

• Use clean, fresh water in buckets or automatic waterers.
• In winter, make sure water isn’t frozen.
• Offer warm water to encourage drinking in cold weather.
• Add a salt block or mix electrolytes in water if necessary.

Step 8: Consider Supplements with Care

The supplement aisle can be overwhelming, but not every horse needs them. Only add supplements when a specific need arises—like joint support, calming aids, or hoof health.

Common Useful Supplements:

• Omega-3 fatty acids (for coat, joints, inflammation)
• Biotin and zinc (for hooves)
• Probiotics (for digestive support)
• Electrolytes (for horses in hot weather or heavy training)

Always choose high-quality products with transparent ingredient lists. Avoid over-supplementation, which can cause imbalances or toxicity.

Step 9: Monitor and Adjust Regularly

Once your horse feeding plan is in place, don’t set it and forget it. Check in regularly to make sure it’s still working.

Monitor for Signs of Nutritional Health:

• Shiny coat and healthy skin
• Strong hooves
• Consistent body condition
• Good energy levels and performance
• Normal manure and digestion

If your horse gains or loses weight unexpectedly, becomes lethargic, or has digestive issues, reassess the diet. Keep records of what your horse eats, changes you make, and any effects noticed.

Step 10: Work with a Professional

Even experienced horse owners benefit from consulting with a vet or equine nutritionist. These professionals can evaluate hay quality, test for deficiencies, and create custom feeding plans that factor in all variables.

Vet checkups are also a good time to:

• Review your horse’s body condition score.
• Check for signs of metabolic diseases.
• Adjust diets based on seasonal or age-related changes.

FAQs About Horse Feeding

Q: How many times a day should I feed my horse?
A: Ideally, horses should eat small amounts throughout the day to mimic natural grazing. If feeding grain or concentrates, split them into at least two meals.

Q: Is it okay to feed a horse just grass?
A: High-quality pasture can meet many horses’ needs, especially easy keepers. However, in winter or dry climates, supplementation with hay and possibly a ration balancer is necessary.

Q: Can I feed my horse human food like apples or carrots?
A: Yes, in moderation. Apples and carrots are safe treats, but avoid sugary or processed foods. Never feed chocolate, onions, or bread.

Q: What are signs that my horse’s diet is lacking something?
A: Poor coat, dull eyes, weak hooves, weight loss or gain, lethargy, or digestive upset can all indicate dietary imbalances.

Q: Do horses need grain every day?
A: Not necessarily. Many horses do fine on hay and a mineral balancer. Grain is only needed for horses with high energy demands or specific deficiencies.
