Equine nutrition is foundational for maintaining your horse’s soundness and peak performance. While genetics and conformation are factors, balanced nutrition is crucial in building strong bones, supporting joint health, and maintaining resilient hooves.

This guide dives into the key nutrients and feeding practices that support soundness, particularly for performance horses and those with conformation challenges.

Essential Nutrients for Equine Soundness and Health

Horse soundness starts with a balanced diet that supplies the body with the necessary building blocks. Here are the primary nutrients critical for maintaining bone, joint, and hoof health:

• Protein: Vital for muscle, tendon, and ligament development. Growing horses, pregnant or lactating mares, and performance horses have higher protein needs. For instance, high-quality alfalfa or a fortified grain mix can meet these requirements.
• Carbohydrates: As the primary energy source, carbohydrates from forage and grains fuel your horse’s activities. Quality sources like oats or barley are ideal for performance horses due to their digestibility and energy density.
• Fats: Offering a concentrated energy source, fats also support a healthy coat and skin. Look for stabilized rice bran or flaxseed oil, both commonly used to add calories without causing digestive issues.
• Vitamins and Minerals: Critical for numerous bodily functions, such as bone strength, immune support, and cellular repair. Key minerals for soundness include calcium, phosphorus, copper, and zinc. Maintaining a 2:1 calcium-to-phosphorus ratio is essential for strong bones, particularly in young and growing horses.

Forage: The Foundation of Equine Nutrition

Quality forage forms the backbone of any equine diet, offering essential fiber and supporting digestive health. Here’s a look at common forage types and their benefits:

• Grass Hay: Suitable for most horses, it provides a balanced nutrient profile. Orchard or timothy hay, for instance, are excellent choices for maintaining body condition in adult horses.
• Legume Hay (Alfalfa): Higher in protein and calcium, making it ideal for growing horses, lactating mares, and performance horses that need more energy and nutrients for recovery.
• Pasture Grazing: Fresh pasture provides natural nutrients and satisfies the horse’s instinct to graze. Keep in mind that pasture quality varies with season and management, so supplementing with hay might be necessary, especially in colder months.

Tip: Always ensure that your hay is free of mold and dust to avoid respiratory issues, and aim to provide at least 1-1.5% of your horse’s body weight in forage daily.

Feeding Strategies for High-Performance Horses

Performance horses require tailored feeding practices to meet the demands of their athletic activities. Their diets should be adjusted according to workload and discipline, balancing energy, hydration, and recovery:

• Increased Energy: High-calorie feeds are essential for horses with intense training schedules. For my seven racehorses, I use a mix of grains like oats and corn and high-fat feeds to provide a steady energy source that fuels them through rigorous training sessions.
• Electrolyte Balance: Replenishing electrolytes lost through sweat is vital to prevent dehydration and muscle fatigue. I make it a point to provide electrolyte supplements before and after each intense exercise session, especially in warmer weather when the risk of dehydration is higher.
• Forage and Grazing: In addition to grain, I prioritize a forage-first approach. I provide my horses with alfalfa and grass hay to meet their fiber needs, and I turn them out daily so they can naturally graze. This routine supports their digestive health and allows them to satisfy their natural grazing instincts, contributing to their overall soundness.
• Targeted Supplements: Consider specialized feeds or supplements to support specific needs. For example, adding a joint supplement with glucosamine and MSM helps maintain joint health, especially for horses that endure high-impact activities. I use joint supplements for my racehorses, as they support healthy cartilage and joint resilience through training and racing.

Nutritional Support for Conformation Challenges

Certain conformation flaws may predispose horses to joint stress or hoof weakness. Tailored nutritional strategies can provide targeted support:

• Joint Support: Supplements containing glucosamine, chondroitin sulfate, and hyaluronic acid help maintain healthy cartilage and joint function. These supplements have been invaluable for my horses with heavier workloads in supporting soundness.
• Hoof Health: Biotin, methionine, and zinc are essential for strong hooves. If your horse is prone to hoof problems, consider a hoof supplement to support growth and resilience.
• Weight Management: Maintaining a healthy weight reduces stress on joints and hooves. Adjust your horse’s diet based on their body condition score to prevent strain and injury.

Identifying Nutritional Deficiencies in Horses

Monitoring your horse’s physical condition is crucial, as deficiencies can affect performance and overall health. Watch for these signs:

• Poor Performance: Low energy levels, muscle loss, or decreased stamina can indicate insufficient nutrients.
• Dull Coat: A dry, dull coat may point to a deficiency in essential fatty acids or vitamins, such as vitamin E.
• Hoof Issues: Cracking, chipping, or slow growth often suggests a lack of biotin or other nutrients crucial for hoof health.
• Behavioral Changes: Signs like irritability, nervousness, or wood chewing can be indicators of mineral imbalances.

When and How to Use Equine Supplements

Supplements can effectively fill dietary gaps, but they should enhance—not replace—a balanced diet. Here are a few common supplements:

• Joint Supplements: Ingredients like glucosamine and MSM support cartilage health and joint lubrication, which is essential for horses engaged in high-impact activities.
• Electrolytes: Use electrolyte supplements to replenish lost salts after workouts, especially in warmer weather, to prevent dehydration.
• Vitamin and Mineral Balancers: If your horse relies on forage with limited nutrient diversity, a balancer ensures they get essential vitamins and minerals.
• Probiotics and Prebiotics: Adding probiotics supports a balanced gut, especially during diet changes or for horses prone to stress-induced digestive issues.

Note: Consult with your veterinarian before adding supplements. They can tailor recommendations to your horse’s specific needs.

Preventing Digestive Issues from Improper Feeding

Improper feeding practices can disrupt a horse’s sensitive digestive system, leading to issues like colic, ulcers, and laminitis. Here’s how to minimize these risks:

• Avoid Large Grain Meals: Feeding too much grain at once can overwhelm the digestive system. Opt for smaller, more frequent meals to ensure gradual digestion.
• Gradual Diet Changes: Sudden changes in diet can shock a horse’s system. When switching feed, increase or decrease amounts over 7–10 days.
• Provide Ample Forage: A forage-first diet maintains gut motility and reduces the risk of colic. Aim for 1–1.5% of the horse’s body weight in forage daily.
• Maintain Hydration: Dehydration can exacerbate digestive problems. Ensure your horse has constant access to fresh water, especially after exercise.

Preventing digestive issues through careful feeding practices supports soundness and contributes to your horse’s comfort and overall performance.
