Feed for Young Horses is more than just a daily routine — it’s a cornerstone of their lifelong health, strength, and success. Whether you’re a first-time breeder or a seasoned horse owner, the choices you make in these early months can shape everything from skeletal growth to immunity, behavior, and athletic potential. With so many options, terms, and feeding philosophies out there, it’s easy to feel overwhelmed. That’s why we’ve crafted this practical, science-backed guide just for you — to help you confidently nourish your young horses from the inside out.
Let’s explore what really matters when it comes to feeding foals and weanlings — and how you can get it right from day one.
Why Choosing the Right Feed for Young Horses Matters
Think of early nutrition as laying the foundation for a house. A weak foundation can’t support a strong structure. Similarly, inadequate or imbalanced nutrition in young horses can lead to developmental orthopedic diseases (DOD), stunted growth, or poor muscle tone. A study published in the Journal of Equine Veterinary Science found that improper mineral ratios, especially calcium and phosphorus, are strongly associated with skeletal deformities in foals.

Feeding the right nutrients at the right time helps young horses grow into strong, healthy adults with fewer health problems and better performance outcomes — whether they’re destined for show jumping, racing, or recreational riding.
Key Nutritional Needs of Foals and Weanlings
Foals grow at an astonishing rate, doubling their birth weight within the first two months. This rapid development requires high-quality nutrients that support bone formation, joint health, and muscle growth. Here’s a breakdown of what they need most:
-
Protein: Especially lysine — an essential amino acid for muscle and tissue development. Aim for 14–16% crude protein in early feeds.
-
Energy: Provided mainly by fats and carbohydrates. Avoid feeds with excessive sugar or starch to reduce the risk of digestive upset.

-
Fiber: Encourages a healthy gut. Good sources include beet pulp, hay, and pasture grasses.
-
Vitamins & Minerals: Calcium and phosphorus (in a 2:1 ratio) are crucial for bone growth. Zinc, copper, and manganese also play key roles.
A balanced diet isn’t just about adding more — it’s about adding smart.
What to Look for in Commercial Feed for Young Horses
Not all commercial feeds are created equal. Look for labels that specify they’re formulated for foals, weanlings, or “growing horses.” These are carefully designed with optimal nutrient profiles.
Here’s what to prioritize on the label:
-
Fixed ingredient formulas (not vague terms like “grain byproducts”)
-
Specific vitamin and mineral levels, especially calcium, phosphorus, and copper

-

-
Added probiotics or prebiotics for gut health
Avoid: Feeds high in molasses (too much sugar), urea (not suitable for horses), and unbalanced cereal grains like cracked corn.
Balancing Forage and Concentrates in a Young Horse’s Diet
While young horses do need grain-based concentrates for growth, forage remains the backbone of equine nutrition. Pasture or high-quality hay provides essential fiber and stimulates natural grazing behavior.

Recommended ratio:
Start with 70% forage and 30% concentrates for foals, adjusting as they age. By 12 months, the diet should consist of 80–90% forage and 10–20% concentrate, depending on workload and body condition.
Always introduce new feeds gradually to prevent colic or digestive upset.
Common Feeding Mistakes Breeders Should Avoid
Even with good intentions, it’s easy to make feeding mistakes that can derail a young horse’s health. Here are some common pitfalls to steer clear of:
-
Overfeeding concentrates: Can lead to obesity and DOD.
-
Underfeeding: Results in stunted growth or poor immunity.

-
Improper calcium-to-phosphorus ratio: This can impair bone development.
-
Inconsistent feeding schedules: Horses thrive on routine.
Pro tip: Work with an equine nutritionist to tailor a plan based on your foal’s breed, age, and activity level.
The Role of Supplements in Young Horse Nutrition
Should you supplement? The answer depends on your base diet. If you’re feeding a balanced commercial product and good forage, your foal may not need much else. But in some cases, supplementation is essential.

Useful supplements for young horses:
-
Calcium & Phosphorus: If hay is low in calcium.
-
Joint support: Products with glucosamine, chondroitin, and MSM.
-
Vitamin E and selenium: Especially in selenium-deficient regions.
Always consult with a vet or equine nutritionist before adding supplements — more isn’t always better.
Transitioning from Milk to Solid Feed: What You Need to Know
Weaning is one of the most stressful phases for a young horse — emotionally and nutritionally. Typically done around 4–6 months, this is when the foal shifts from a milk-based diet to solids.
To ease the process:
-
Introduce foal starter feed as early as 2–3 weeks of age in small, frequent meals.
-
Offer soft, palatable hay alongside milk to encourage chewing.
-
Gradually reduce milk intake or mare contact over 2–3 weeks.

Use tools like weight tapes, growth charts, and body condition scoring (BCS). Partner with your veterinarian to check for any red flags like limb deformities or potbellies.
Tailoring Feed for Young Horses by Breed and Purpose
A Shetland pony foal and a young Thoroughbred race prospect don’t have identical needs. Breed, body size, and future use play a big role in feed selection.
-
Draft breeds: Grow slower, need less energy-dense feed.
-
Thoroughbreds & warmbloods: May require more calories and protein for rapid growth.
-
Ponies: Prone to weight gain; need high-fiber, low-calorie diets.
