Beet Pulp for Horses: Benefits, Risks, and How To Feed

Beet pulp is a popular feed room ingredient in many horse barns. It provides highly digestible fiber and calories mainly from fiber fermentation, making it useful for horses who need extra calories, without relying heavily on high-starch, high-sugar feeds.

Here’s what horse owners should know about the benefits and potential drawbacks of feeding beet pulp, and how to safely incorporate this fibrous feed into your equine companion’s diet. 

What Is Beet Pulp?

Beet pulp is the fibrous material left after extracting sugar from sugar beets. It’s a highly digestible fiber source and is commonly classified as a non-forage fiber feed.  

Beet pulp for horses is sold as either shreds or pellets. Shredded beet pulp has a loose, fluffy texture, while pellets are more compact. 

You'll find beet pulp sold plain, unmolassed, or with added molasses. Molassed products are more palatable but contain added sugar, which matters when choosing a feed for horses who need careful management of dietary sugar. 

Beet pulp is generally low in starch, making it an appealing option for horses whose diets require restricted non-structural carbohydrates (NSC), such as horses with insulin dysregulation (IR), equine metabolic syndrome (EMS), obesity, or laminitis (founder). 
 
Because beet pulp is a fiber source, not a complete feed, it does not meet all of a horse’s nutritional needs on its own. Before adding beet pulp to the ration, check the product label for its calorie, protein, sugar, and mineral content, as well as the manufacturer's feeding and preparation instructions. 

Benefits of Beet Pulp for Horses

Feeding beet pulp offers several benefits for horses:  

1. It Provides Digestible Fiber and Safe Calories 

One of the biggest appeals of feeding beet pulp is its highly digestible fiber—and fiber should be the foundation of the equine diet. Fibrous beet pulp provides “safe calories,” mainly through fiber fermentation rather than the starch found in many grain-based feeds. 

This makes it particularly useful for metabolically compromised horses who need to maintain weight while limiting starch and sugar intake from grain and fresh grass. 
 
However, beet pulp isn't a cure-all for weight loss. If your horse is dropping weight inexplicably, evaluate underlying causes, including dental disease, gastric ulcers, and internal parasites. 

2. It’s Safe for Senior Horses with Dental Issues 

Beet pulp can be useful for senior horses with dental disease that makes chewing hay difficult. Once properly soaked, it softens and becomes easier to chew and swallow. 

3. It Can Provide Partial Hay Replacement 

Beet pulp can provide fiber when hay is limited or poor quality, or when a horse has difficulty chewing it. However, quality hay should remain the foundation of the diet whenever possible. 

4. Key Features Include Palatability and Versatility 

Many horses readily eat beet pulp. Soaked beet pulp can be mixed with other feeds, a ration balancer, or supplements to create a palatable meal for picky eaters.

Potential Drawbacks and Risks

Beet pulp comes with a few nutritional and management considerations:  

1. Calcium-to-Phosphorus Balance

Beet pulp is relatively high in calcium and low in phosphorus, which can skew the overall diet ratio when it is fed in large amounts. Consider its mineral contribution alongside the horse's hay, concentrates, ration balancer, and supplements. Some beet pulp-heavy diets may require supplemental phosphorus. 

Beet pulp is commonly paired with stabilized rice bran—the nutrient-rich outer layer of the rice grain that provides fat-based calories—because rice bran is high in phosphorus.

2. Added Sugar 

Molassed beet pulp contains added sugar. This matters for horses with insulin dysregulation, EMS, obesity, or a history of laminitis. 

For these horses, an unmolassed product may be preferable. 

3. Choke Risk 

Dry beet pulp, particularly pellets, can be consumed quickly, increasing the risk of esophageal obstruction (choke). Soaking reduces that risk and makes the feed easier to consume.

4. Too Many Calories

Feeding too much beet pulp can contribute to unwanted weight gain if fed alongside an already complete diet. Measure beet pulp by weight rather than by scoop, and include its calories when calculating the horse's total daily ration.

When To Feed Beet Pulp

This fiber-rich feed can benefit a range of horses, including: 

• Underweight or hard-keeping horses: To provide additional digestible calories and fiber 
• Senior horses: As a softened source of fiber when dental problems limit hay intake 
• Horses with limited hay access: As a partial forage substitute 
• Horses needing additional fiber: As an alternative to adding more grain-based calories 
• Picky horses: As a palatable carrier for supplements, medications, or ration balancers 

The horse's body condition, age, dental health, workload, and existing diet should determine whether adding beet pulp may be beneficial. A veterinarian or equine nutritionist can help you consider all these factors and make an educated recommendation. 

How To Safely Feed Beet Pulp To Horses

To safely feed beet pulp to horses, start with the manufacturer's feeding and soaking instructions. Commercial products vary, so no single soaking time or feeding rate applies to every type of beet pulp. 

To ensure consistent portions, weigh beet pulp rather than relying on a measuring scoop. If soaking, let the product hydrate and expand fully before feeding. Prepare only what the horse will consume promptly, and discard any feed that becomes spoiled or fermented. 

Like any other new feed, introduce beet pulp gradually over several days. Divide large amounts into multiple meals rather than feeding all at once. Always keep fresh, clean water available. 

Finally, don't treat plain beet pulp as a complete feed unless the product is specifically formulated for that purpose. 

Beet Pulp vs. Hay and Grain

Beet pulp offers some benefits of both forage and concentrated feeds, but it isn't a direct replacement for either. 

Hay provides long-stem fiber, bulk, and chewing time. Beet pulp provides digestible fiber but much less chewing stimulation. Grain generally provides more concentrated calories from starch. Beet pulp supplies energy primarily through highly digestible fiber. 

Unlike a complete feed, plain beet pulp isn't formulated to supply all the vitamins, minerals, protein, and other nutrients a horse needs. Plain beet pulp isn't nutritionally complete—it works best as one component of a balanced ration, not as the sole feed.

So is beet pulp good for horses? It can be a valuable source of digestible fiber and low-starch calories, particularly for hard-keeping horses, seniors, and horses with limited hay intake. Feed it gradually, follow preparation instructions, and account for its calories and mineral content when balancing the overall diet.
