A horse can look well-fed and still have an unbalanced diet. Calories might be adequate while copper, zinc, vitamin E, or essential amino acids fall short. In another ration, several supplements might provide overlapping nutrients without addressing the horse’s actual limiting factor.
A stepwise review makes these problems easier to spot. It also gives Mad Barn’s equine nutritionists the information they need to build personalized recommendations around the complete diet rather than one feed bag or supplement at a time.
Step 1: Determine What Your Horse Needs
Don’t begin by asking which product to buy. Begin with the horse. Nutrient requirements change with body weight, condition, workload, age, growth, pregnancy, lactation, metabolism, and health status.
Collect the information a nutritionist will need:
- Current weight, body condition, and any recent change
- Workload and activity level
- Age, life stage, and relevant health or metabolic concerns
- Every forage, feed, and supplement, including the amount consumed
- Specific goals involving condition, hooves, muscle, digestion, or performance
A balanced ration supplies enough energy and protein for these needs without significantly exceeding them. It also provides adequate vitamins and minerals in appropriate ratios that support normal absorption and use.
Step 2: Account for Forage, Water, and Salt
Forage should be assessed first because it makes up most of the diet and contributes substantial calories, protein, fiber, and minerals. Fiber supports digestive function and fuels the microorganisms responsible for hindgut fermentation.
Hay and pasture can vary widely with plant species, maturity, growing conditions, harvest, and storage. Two hays that look alike can provide different amounts of energy, protein, sugar, starch, and minerals.
Use a forage analysis when possible. Mad Barn’s nutritionists can interpret the results and determine which feeds or supplements complement the forage.
Next, account for fresh water and salt. Water supports digestion, circulation, temperature regulation, and gut motility. Salt supplies sodium and chloride, supports fluid balance, and helps stimulate thirst. Horses that sweat heavily might also need electrolyte supplementation.
Step 3: Identify the Kind of Gap
When Your Horse Needs More Calories or Protein
Many mature horses at maintenance can meet their calorie and protein needs from good-quality forage. Horses in heavier work, growing horses, lactating mares, and hard keepers often need more. Depending on the ration, the right addition could be higher-calorie forage, digestible fiber, fat, or an appropriate fortified feed.
When Weight Is Fine but the Diet Is Still Incomplete
Maintaining condition does not prove that vitamin, mineral, and amino-acid intake is adequate. Forage-based diets can still fall short in copper, zinc, selenium, iodine, vitamin E, or essential amino acids. A concentrated vitamin and mineral supplement can address these gaps without requiring more calorie-containing feed.
Step 4: Choose the Right Vitamin and Mineral Base
Once you have a clear idea of your horse’s needs, the next step is to ensure any gaps are filled. A complete vitamin and mineral supplement is an effective option for balancing the diet without adding unnecessary sugar, starch or excess calories.
Omneity® is Mad Barn’s complete vitamin and mineral supplement recommended for most horses on forage-based diets. It provides vitamins, organic trace minerals, B-vitamins, biotin, lysine, methionine, threonine, digestive enzymes, and live yeast culture.
Choose Omneity® when your horse maintains condition on forage and needs a complete source of commonly missing vitamins, minerals, and essential amino acids without significant added calories, sugar, or starch. This science-backed formula supports hoof and coat quality, muscle function, digestive health, and overall well-being.
AminoTrace+ provides higher levels of copper, zinc, magnesium, essential amino acids, and natural vitamin E than Omneity®, as well as chromium. Its low-NSC formula contains no added iron and includes a proprietary gut-support blend. AminoTrace+ is usually a good choice for horses with metabolic concerns, a history of laminitis, high-iron forage or water, poor hoof quality, or increased antioxidant and muscle-support needs
Step 5: Add Specialized Supplements Last
Once forage, water, salt, energy, protein, vitamins, and minerals are addressed, consider products for specific goals such as joints, digestion, omega-3 intake, respiratory health, or muscle recovery. A targeted supplement can support a particular system, but it cannot replace a balanced foundation.
Following this order also makes it easier to avoid unnecessary spending and ingredient overlap.
Know When to Check the Diet Again
Review the ration when the hay or pasture changes, workload increases or decreases, body condition shifts, or the horse enters a new life stage. Introduce feeding changes gradually and monitor weight, appetite, behavior, performance, hoof and coat quality, and manure.
Seek veterinary guidance for sudden or unexplained changes because pain, dental disease, parasites, endocrine disorders, and other medical conditions can also affect appetite, condition, and performance.
