Key Takeaways

• Pelleted feeds produce lower blood glucose and insulin responses than textured feeds, making them safer for horses with EMS, insulin resistance, and Cushing’s disease.
• Uniform pellets prevent horses from sorting out high-sugar ingredients, ensuring consistent nutrition in every bite.
• Low-starch pelleted feeds keep non-structural carbohydrates (NSC) below 13.5%, providing balanced energy without dangerous insulin spikes.
• Textured feeds allow selective eating and often contain molasses and grains that spike blood sugar levels.
• Always choose feeds with NSC content below 10-12% for metabolic horses and work with an equine nutritionist for best results.

Pelleted feed is the better choice for horses with metabolic issues because it produces lower insulin and glucose responses while preventing selective eating that can lead to nutritional imbalances. The uniform processing and controlled NSC content make pelleted feeds safer and more predictable for managing conditions like Equine Metabolic Syndrome.

Understanding the Feed Forms: Pelleted vs Textured

When managing horses with metabolic conditions, the form of feed you choose matters just as much as its nutritional content. Both pelleted and textured feeds have distinct characteristics that directly impact how your horse’s body processes nutrients.

What Makes Pelleted Feed Different

Pelleted feeds combine all ingredients into uniform, compressed pellets through a manufacturing process that involves grinding, mixing with steam, and pressing through dies. This heat treatment causes natural starches in grains to gelatinize, breaking down complex carbohydrate bonds and making them more digestible.^[2]

The uniform shape of each pellet ensures your horse gets the exact same nutrition in every mouthful. Research shows that pelleted feeds produce significantly lower blood glucose and insulin responses after meals compared to textured feeds, which is crucial for horses battling insulin resistance.^[7] One study found that pelleted feeds elicited lower insulin concentrations at 5.5 hours post-feeding than both extruded and oval-shaped feeds.^[7]

Beyond metabolic benefits, pelleted feeds offer increased dry matter and organic matter digestibility. Studies conducted at Texas A&M University noted that horses consumed pellets more quickly, reflecting better palatability, while also showing significant improvements in digestibility.^[8]

The Challenge with Textured Feeds

Textured feeds—also called sweet feeds or coarse mixes—are loose blends where you can see individual ingredients like whole oats, corn, rolled barley, and often molasses. While they look appealing and horses find them tasty, they present serious problems for metabolic horses.

The biggest issue is selective eating. Horses naturally pick out the tastiest, highest-sugar particles and leave behind the fortified pellets that contain essential vitamins and minerals. This sorting behavior means each bite delivers inconsistent nutrition, and your horse may be getting more sugar and starch than intended while missing out on critical nutrients.

Traditional textured feeds typically contain higher NSC content due to molasses (used as a binding agent) and whole grains. These ingredients trigger sharper glucose and insulin spikes—exactly what metabolic horses need to avoid.^[1]

Why Blood Glucose and Insulin Response Matter

For horses with Equine Metabolic Syndrome (EMS), insulin resistance, or Cushing’s disease (PPID), controlling post-meal blood glucose and insulin levels isn’t just important—it’s essential for preventing laminitis and managing their condition.

The Insulin Resistance Connection

When a horse eats, carbohydrates break down into glucose, which enters the bloodstream. The pancreas releases insulin to help cells absorb this glucose for energy. In insulin-resistant horses, cells don’t respond properly to insulin, so the pancreas pumps out more and more insulin trying to force glucose into cells.^[5]

This creates a dangerous cycle: high insulin levels circulating in the blood can trigger laminitis, the painful and potentially career-ending hoof condition that affects up to 27% of horses with metabolic issues.^[15] Keeping glucose and insulin responses as low and stable as possible following meals is the cornerstone of managing these conditions.

How Feed Form Affects Insulin Response

Research conducted at Virginia Tech examined how different feed forms impact metabolic responses in horses. The study found that pelleted feeds caused significantly lower glucose and insulin responses after the evening meal compared to extruded feeds.^[8] Another study demonstrated that feeding a low NSC concentrate resulted in lower overall glucose and insulin response to feeding.^[6]

The manufacturing process matters. When grains are ground and steam-heated during pelleting, the starch becomes more uniformly digestible, leading to a slower, steadier release of glucose rather than the sharp spikes seen with whole or cracked grains in textured feeds.^[10]

Low-Starch Pelleted Feeds: The Gold Standard for Metabolic Horses

Not all pelleted feeds are created equal. The key to successful metabolic management lies in choosing specifically formulated low-starch, low-sugar pelleted feeds that keep total NSC content below the critical threshold.

Understanding Non-Structural Carbohydrates (NSC)

NSC is the sum of starches, sugars, and fructans—the easily digestible carbohydrates that cause rapid increases in blood glucose. For horses with metabolic disorders, the total diet (including forage) should ideally contain 10-12% NSC or less on a dry matter basis.^[5][11]

Dr. Kathleen Crandell, a nutritionist at Kentucky Equine Research, explains: “Horses with EMS typically are overweight, resistant to the normal effects of insulin to control blood sugar levels, and at risk of developing laminitis.”^[18] She emphasizes that forage should have less than 10-12% NSC to reduce the risk of hyperinsulinemia and laminitis.

Top Low-Starch Pelleted Feed Options

Several manufacturers produce excellent low-starch pelleted feeds designed specifically for metabolic horses. Popular options include Tribute’s Kalm ‘N EZ Pellet, Triple Crown Low Starch, Nutrena Safe Choice Special Care, and Purina WellSolve Low Starch. These feeds typically contain NSC levels below 13.5% and are formulated with high fiber and fat content to provide balanced energy without dangerous blood sugar spikes.^[1]

These specialized feeds replace high-starch grains with safer energy sources like beet pulp (rinsed to remove sugars), soy hulls, rice bran, and vegetable oils. The result is a feed that provides necessary calories and nutrition without triggering the insulin response that puts metabolic horses at risk.

When to Use a Ration Balancer Instead

For easy keepers—horses that maintain weight on forage alone—a low-NSC pelleted ration balancer may be the better choice. These concentrated pellets provide essential vitamins, minerals, and protein in a very small serving size (typically 1-2 pounds per day), adding minimal calories while ensuring nutritional needs are met.^[1][21]

Amy Parker, MS, PhD, an equine nutritionist at McCauley’s, notes that “Most horses that we consider easy keepers need only a ration balancer that provides the required vitamins and minerals without adding more calories.”^[20]

The Sorting Problem: Why Textured Feeds Fail Metabolic Horses

Even if you purchase a “low-starch” textured feed, your horse’s natural feeding behavior can undermine your management efforts. Horses are selective eaters, and when given the opportunity, they’ll sort through their feed to find the tastiest morsels.

Selective Eating Leads to Imbalanced Nutrition

In textured feeds, the most palatable ingredients are often the worst for metabolic horses: molasses-coated grains, corn, and sweet-tasting particles. When horses pick out these high-NSC components first and leave the fortified pellets (which contain vitamins, minerals, and protein) at the bottom of the bucket, they’re getting the opposite of what they need.

This selective eating creates two problems:

• Higher than intended NSC intake: Your horse consumes more sugars and starches than the feed tag suggests
• Nutritional deficiencies: Essential vitamins and minerals remain uneaten in the feed bucket

How Pelleting Eliminates Sorting

Because every pellet is identical, containing the exact same proportion of all ingredients compressed together, your horse cannot sort through and select only certain components. The first bite and the last bite deliver identical nutrition. This consistency is essential for managing metabolic conditions where predictable, controlled nutrition is paramount.^[1]

As one nutritionist explains, “The number-one advantage of pelleting is feed uniformity, so one mouthful is the same as the next, and fine material can’t be sifted out or left in the bottom of the bucket.”^[8]

Digestibility and Processing: The Science Behind Better Feeds

The manufacturing process doesn’t just affect consistency—it fundamentally changes how horses digest and metabolize their feed.

Steam Processing and Starch Gelatinization

During the pelleting process, ingredients are subjected to steam heat and pressure. This treatment causes starch gelatinization—a chemical change where complex carbohydrate structures partially break down. While this makes starch more digestible, it also means the digestive process is more predictable and steady.^[8]

Research from Norway found better prececal protein digestibility with pelleted grains than extruded products, likely due to improvements in pelleting technology in recent years.^[8] This enhanced digestibility means horses extract more nutrition from smaller amounts of feed.

Consumption Rate and Metabolic Impact

Studies examining feed form found that consumption time correlates with glucose and insulin response—the faster a horse eats, the sharper the glucose spike.^[7] Interestingly, while horses may consume pelleted feeds slightly faster than textured feeds (suggesting better palatability), the uniform processing still results in lower overall insulin response.^[8]

For horses that bolt their feed too quickly, soaking pelleted feeds into a mash slows consumption while maintaining nutritional consistency—an option that doesn’t work well with textured feeds, which separate when wet.

Practical Feeding Strategies for Metabolic Horses

Choosing the right feed form is just the beginning. How you manage your entire feeding program determines success in controlling metabolic conditions.

Building a Forage-First Diet

Forage should form the foundation of any metabolic horse’s diet. Quality hay (tested to ensure NSC below 10-12%) fed at 1.5-2% of body weight daily provides essential fiber for gut health while limiting calorie intake.^[5][11]

If hay NSC is too high, soaking for 30-60 minutes (or longer in cold water) can reduce sugar content. Warm-season grass hays like Bermuda grass or teff typically have naturally lower NSC than cool-season grasses like timothy or orchard grass.^[22]

For more information on safe forage options, see our article on Best Low Sugar Feeds for Weight Management in EMS Horses.

Portion Control and Meal Frequency

Multiple small meals throughout the day produce lower, more stable glucose and insulin responses than one or two large meals. If feeding concentrates, divide the daily ration into 3-4 smaller servings.^[21]

For pelleted ration balancers, feed according to the manufacturer’s recommendations based on your horse’s weight. These are typically very small amounts (1-2 pounds per day) but pack concentrated nutrition.

Monitoring and Adjusting

Work with your veterinarian to regularly test your horse’s insulin levels and adjust feeding strategies accordingly. What works initially may need modification as your horse’s condition improves or changes.

Body condition scoring every 2-4 weeks helps track progress. For horses with active EMS, the goal is gradual weight loss of 0.5-1% of body weight per week while maintaining muscle mass and energy levels.

Real-World Application: Success Stories

Research from insulin dysregulation studies shows clear benefits of proper feed management. In a study examining horses with insulin dysregulation fed low-NSC pelleted forage, researchers found that these horses showed no augmented insulinemic response compared to a control diet, indicating safety for metabolic animals.^[12] The study concluded that low-NSC forage pellets “could be a safe feedstuff for ID animals” when fed appropriately.

Another study tracking overweight Arabian geldings demonstrated that switching from high-NSC to moderate-NSC hay significantly improved insulin and glucose concentrations over an eight-week period.^[13] When combined with appropriate pelleted feeds and exercise, horses showed measurable improvements in metabolic markers.

Pelleted Feed vs Textured Feed for Horses with Metabolic Issues FAQs

Can I mix pelleted feed and textured feed for my metabolic horse?

Mixing pelleted feed and textured feed is not recommended for metabolic horses. The textured components allow selective eating, where horses pick out high-sugar grains and leave fortified pellets behind, defeating the purpose of controlled nutrition. Stick to either a complete low-NSC pelleted feed or a pelleted ration balancer for consistent results.

Are pelleted feeds safe for senior horses with dental issues?

Yes, pelleted feeds are excellent for senior horses because they can be soaked into a soft mash that’s easy to chew and swallow. This makes pelleted feeds particularly suitable for older metabolic horses who may have both dental problems and metabolic issues. Soak pellets 15-30 minutes before feeding for best results.

How do I know if a pelleted feed is truly low in starch and sugar?

Always check the guaranteed analysis on the feed tag for combined starch and sugar (NSC) content, which should be 12% or less for metabolic horses. Look for feeds specifically labeled “low-NSC,” “low-starch,” or “molasses-free.” Reputable manufacturers will provide NSC percentages on their websites or feed tags.

Why does my horse’s pelleted feed cause less insulin spike than the textured feed we used before?

Pelleted feeds produce lower insulin responses because the manufacturing process creates more uniform starch digestibility, leading to slower, steadier glucose release rather than sharp spikes. Additionally, properly formulated low-NSC pelleted feeds simply contain less of the sugars and starches that trigger insulin release, and the uniform shape prevents horses from sorting out higher-sugar components.

What is the best pelleted feed for horses with metabolic issues?

The best pelleted feed depends on your horse’s individual needs, but popular options include Tribute Kalm ‘N EZ Pelleted (under 11% NSC), Triple Crown Low Starch (10% NSC), Nutrena Safe Choice Special Care (11.5% NSC), and Purina WellSolve Low Starch (10.5% NSC). For easy keepers, a ration balancer like Kentucky Equine Research Micro-Max or Mad Barn AminoTrace Plus may be more appropriate than a complete feed.
