What Do Stallions Eat? Stallions eat a diet primarily composed of high-quality forage like hay or grass, supplemented with grains, concentrates, and occasionally vitamins and minerals to support their energy needs, muscle development, and overall health.
Providing the right diet is essential for keeping these male horses strong and healthy, especially considering their higher energy requirements compared to mares or geldings.
Understanding the Diet of Stallions
Stallions, as active male horses, often have different dietary needs than other horses, especially if they are being used for breeding, working, or competing. A balanced diet ensures they receive the energy, protein, and nutrients required for their daily activities and reproductive health.
Forage: The Foundation of a Stallion’s Diet
Forage, including hay and pasture grass, is the cornerstone of a stallion’s diet. It provides the fiber needed for proper digestion and a steady energy source.
- Types of hay: Alfalfa, timothy, and orchard grass are common choices for stallions. Alfalfa is richer in protein, making it suitable for more active stallions.
- Grazing: Stallions benefit from grazing on fresh pasture whenever possible, as it offers natural nutrients and encourages healthy digestion.
- Daily intake: Forage should make up at least 50-70% of a stallion’s daily diet, with 1.5-2% of their body weight in forage recommended per day.
According to The Horse, forage is essential for all horses, providing the bulk of their nutrition and promoting gut health through its high fiber content.

Grains and Concentrates: Meeting Higher Energy Needs
While forage provides the foundation, grains and concentrates are often added to a stallion’s diet to meet their higher energy and nutritional needs.
- Common grains: Oats, barley, and corn are popular choices. They provide extra calories for stallions with high activity levels.
- Commercial concentrates: Formulated feeds designed for stallions often include a balanced mix of grains, proteins, and minerals, making it easier to ensure their nutritional needs are met.
- Feeding guidelines: Grains and concentrates should be fed in moderation, usually comprising 20-30% of the diet, to prevent weight gain and digestive issues.
Dr. James Miller, an equine nutritionist, notes, “For active stallions, concentrates can provide the extra calories and protein needed to support their energy demands. However, it’s crucial to balance these with adequate forage to maintain digestive health.”
Equine Wellness Magazine suggests that adding grains to a stallion’s diet can help support their increased metabolic needs, especially during breeding season or intensive training.

Vitamins and Minerals: Supporting Overall Health
Stallions may require additional vitamins and minerals to support their overall health, reproductive system, and muscle maintenance.
- Essential minerals: Calcium and phosphorus are vital for bone health, while magnesium supports muscle function.
- Supplements: Vitamin E, selenium, and omega-3 supplements are often recommended to enhance coat quality, immune function, and muscle health.
- Electrolytes: Stallions that sweat heavily during exercise or in hot climates may need electrolytes to replenish minerals lost through sweat.
According to Kentucky Equine Research, a balanced intake of vitamins and minerals is crucial for maintaining the health of stallions, especially those used for breeding or competitive activities.
Water: Essential for Digestion and Hydration
Stallions, like all horses, require constant access to fresh, clean water. Adequate hydration is critical for digestion and overall health.
- Water needs: A stallion typically drinks 5-10 gallons of water per day, though this can increase in hot weather or during periods of physical exertion.
- Water quality: Ensure water sources are clean and free from contaminants to prevent digestive issues.

Foods to Avoid When Feeding Stallions

When feeding stallions, it’s crucial to be aware of certain foods that can be harmful to their health, as they may lead to digestive problems, obesity, or even toxic reactions.
Foods high in sugar or starch can cause metabolic issues such as insulin resistance or laminitis, so it’s best to limit treats like apples and carrots, as well as sweetened feeds or grains heavy in molasses.
Watch for signs of overfeeding, including weight gain, digestive upset, or changes in behavior that may indicate a diet too rich in sugars.
Additionally, some plants and human foods are toxic to horses and should be kept out of their reach; for instance, avoid access to poisonous plants like ragwort, yew, and buttercups, and never give them human foods such as chocolate, onions, and avocados, which are harmful to their health.

Feeding Schedules and Best Practices for Stallions
Establishing a consistent feeding schedule and a balanced diet is essential for maintaining the health of stallions and managing their energy levels effectively.
It’s recommended to divide their feedings into at least two meals per day to help prevent digestive issues and regulate energy.
During active periods, such as training or breeding seasons, you may need to increase the amount of concentrates in their diet, while reducing it during rest periods.
Additionally, it’s important to regularly assess your stallion’s body condition score (BCS) to ensure they remain at an optimal weight, making any necessary dietary adjustments to avoid problems related to obesity or being underweight.

Conclusion
Stallions require a diet rich in high-quality forage, supplemented with grains, vitamins, and minerals to support their energy and nutritional needs.
A balanced diet ensures that these strong male horses stay healthy, active, and ready for whatever tasks lie ahead.
If you are unsure about any aspect of your stallion’s diet, consult with an equine veterinarian to tailor a feeding plan that meets their specific needs.
FAQs
1. How much hay should a stallion eat daily?
Stallions should consume 1.5-2% of their body weight in hay daily, making it the primary part of their diet.
2. Can stallions eat alfalfa?
Yes, alfalfa is a good source of protein for active stallions but should be balanced with other types of hay to prevent excess calcium intake.
3. What supplements are beneficial for stallions?
Supplements like vitamin E, selenium, and omega-3s can benefit stallions, especially those with high activity levels or during breeding season. Always consult a vet before introducing new supplements.
