A few years back, I noticed that even with plenty of good-quality hay, some of my horses didn’t have the energy or condition I expected. Wanting to help them feel and look better, I took a deep dive into horse nutrition and learned the importance of ration balancers.
With 25 years as a racehorse owner and trainer and insights from top equine experts, this guide offers reliable advice on using ration balancers to ensure your horse gets the right nutrients for optimal health, saving you time and money. I’ll share what ration balancers for horses are, their benefits, and practical tips on choosing the best one for your horse.

What is a Ration Balancer?
A ration balancer is a concentrated feed that adds important nutrients to a horse’s hay or pasture diet. Unlike complete feeds, which are intended to replace a portion of the forage, ration balancers are fed in small amounts alongside forage to address nutritional gaps.
Key Characteristics of Ration Balancers:
- Small Feeding Rate: Typically, 1 to 2 pounds per day for a 1,000-pound horse. Stable Management
- High Protein Content: Generally contains 25% to 35% protein.
- Essential Vitamins and Minerals: Provides significant amounts of major and trace minerals.
- Low Calorie Content: Offers approximately 1.2 to 1.5 Megacalories per pound.

Why Use a Ration Balancer?
Hay and grass often don’t have enough of the essential nutrients for your horse’s health. Ration balancers are made to add these missing nutrients, keeping your horse’s diet balanced. They are especially helpful in these situations:
- Forage-Only Diets: When horses are primarily fed hay or pasture, ration balancers supply missing vitamins and minerals.
- Diets Including Grains: Supplementing rations that include grains like oats or corn, which may lack adequate calcium and trace minerals.
- Reduced Concentrate Feeding: Ensuring nutrient requirements are met when horses consume less than the recommended amount of commercial feeds.
- Seasonal Dietary Changes: Maintaining consistent nutrition despite variations in forage quality and availability.
- Easy Keepers: Providing essential nutrients without extra calories for horses that maintain weight easily on forage alone.
- Horses with Metabolic Concerns: Offering controlled diets for horses with metabolic issues or those requiring restricted sugar and starch intake.
It’s important to remember that ration balancers are not intended to provide extra calories. Their primary function is to supplement essential nutrients—protein, vitamins, and minerals—that may be lacking in your horse’s forage-based diet. They are designed for horses that maintain weight easily on forage alone but still require a balanced nutritional profile.

Types of Ration Balancers
Knowing the types of ration balancers and picking the right one is key to meeting your horse’s nutrition needs.
- Protein, Vitamin, and Mineral Balancers: These provide concentrated protein along with essential vitamins and minerals, typically fed at 1 to 2 pounds per day for a 1,000-pound horse. Ker
- Vitamin and Mineral Balancers: These focus on supplying essential vitamins and minerals without significant protein content, which are suitable when forage provides adequate protein but lacks other nutrients.
Hay Analysis Process
Hay analysis is crucial for identifying nutritional gaps in your horse’s diet. By determining the levels of protein, fiber, vitamins, and minerals, you can make informed decisions about supplementation and ensure a balanced diet.
Collecting a Hay Sample:
Your sample must represent the entire hay lot to get the most accurate results. Hay can vary in nutrient content, so taking a good sample is essential.
The best way to do this is by using a core sampler to take samples from multiple bales. Don’t take samples from old or moldy hay, as they don’t show the true quality.

Where to Send Samples:
You can send your hay samples to agricultural extension offices or private testing laboratories. These labs usually provide kits and instructions for collecting and submitting your samples.
Understanding the Hay Analysis Report:
A typical report will include key components like crude protein, fiber (ADF and NDF), energy (digestible energy), and mineral content (calcium, phosphorus, etc.). High fiber can make the hay harder to digest; low protein might mean you need to supplement your hay to ensure your horse gets the correct amount of protein.
Using the Results:
Use your hay test results to pick a ration balancer that fits your horse’s diet. For example, if your hay is low in copper and zinc, select a ration balancer that adequately provides these trace minerals. Understanding a Hay Analysis
How Often to Analyze Hay:
Test your hay often, especially with new batches or if you see quality changes. Remember, seasons can change hay quality, so check nutrient levels all year.
By understanding the importance of hay analysis and following these steps, you can ensure that your horse’s diet is properly balanced, leading to improved health and performance.

Factors to Consider When Selecting a Ration Balancer:
Forage Analysis:
- Testing your hay or pasture helps identify nutritional gaps, allowing you to choose a balancer that complements the existing diet. For a simple guide on testing your hay’s nutrient content, check out Oregon State University Extension Service’s article.
- Example: If a horse grazes on pasture in a region with selenium-deficient soils (such as Ontario, Canada), a ration balancer with added selenium is essential.
Protein Requirements:
- If your forage is low in protein, opt for a balancer with additional protein to meet your horse’s needs.
- Example: If a horse primarily consumes alfalfa hay (a legume), which is generally higher in protein, a ration balancer with lower protein content but focusing on vitamins and minerals might be more suitable.
Life Stage and Activity Level:
- Horses have varying nutritional needs based on age and workload; select a balancer formulated accordingly.
- Example: A high-level athlete, such as a racehorse, requires significant amounts of fortified feed to fuel heavy work. However, when that horse is not training, a ration balancer can provide necessary nutrients without excess calories.
Specific Health Conditions:
- Some balancers are designed for horses with particular health issues, such as metabolic disorders, providing tailored nutrient profiles.
- Example: For horses with equine metabolic syndrome (EMS), selecting a ration balancer with low sugar and starch content is crucial.
Understanding the rationale behind using ration balancers is crucial. Forage alone often lacks essential nutrients required for a horse’s well-being. By supplementing with a suitable ration balancer, you can address these deficiencies, leading to improved health, enhanced performance, and prevention of potential dietary-related issues.

How to Choose a Ration Balancer
Choosing the right ration balancer is key to keeping your horse healthy. Here’s how to make an informed choice:
- Forage Analysis: Begin by testing your hay or pasture to identify nutritional gaps. This analysis provides a baseline for understanding which nutrients are lacking in your horse’s diet.
- Assess Individual Needs: Consider factors such as age, activity level, health status, and specific metabolic conditions. For example, performance horses may require higher protein levels, while easy keepers might need a balancer low in calories.
- Consult Professionals: Consult an equine nutritionist or veterinarian to interpret forage analysis results and tailor a nutrition plan. Their expertise ensures that the chosen ration balancer meets your horse’s requirements.
- Monitor and Adjust: After implementing the ration balancer, observe your horse’s condition and performance. Regular monitoring allows for adjustments to the diet as needed, ensuring optimal health outcomes.
- Evaluate Ingredients: Look for added benefits like digestive aids or immune support, which might reduce the need for extra supplements.
To ensure your horse receives the full benefit of a ration balancer, always adhere to the manufacturer’s recommended feeding amounts. Feeding less than recommended can lead to nutrient deficiencies while overfeeding can create imbalances. Monitor your horse’s condition and adjust the diet as needed in consultation with an equine nutritionist or veterinarian.
By focusing on these factors, you can select a ration balancer that fits your horse’s requirements.
Common Mistakes to Avoid
To get the most out of ration balancers and avoid common mistakes, consider the following tips:
- Follow Feeding Instructions: Always adhere to the manufacturer’s recommended feeding guidelines to ensure your horse receives the correct amount of nutrients.
- Assess Forage Quality: Regularly evaluate the quality of your hay or pasture, as nutrient content can vary. Adjust the ration balancer accordingly to address any deficiencies.
- Adjust for Life Stage: Recognize that horses at different life stages, such as growing foals or senior horses, have varying nutritional needs. Tailor their diet to meet these specific requirements.
- Avoid Over-Supplementation: Be cautious not to provide excessive supplements, which can lead to nutrient imbalances or toxicity.
- Account for Seasonal Changes: Seasonal variations can affect forage availability and quality. Modify your horse’s feeding program as needed throughout the year to maintain balanced nutrition.
By keeping these considerations in mind, you can effectively utilize ration balancers to support your horse’s health and well-being.
