The Skinny On Beet Pulp As An Equine Feed

Fifty years ago, many knowledgeable horsemen would find it difficult to identify beet pulp or its potential value as a feedstuff for horses. Though its usefulness is now cemented among horse owners, beet pulp can still cause some confusion. Dr. Kathleen Crandell, a nutritionist for Kentucky Equine Research, answers eight questions about beet pulp and its role in equine nutrition.

In what types of feeds was beet pulp first used?

Sugar beet pulp first found a use in commercial horse feeds in the racehorse products as a low-dust feedstuff because it was mixed with lots of molasses and felt moist. This proved beneficial for the respiratory tract and was thought to be somehow beneficial in preventing bleeding, though this notion was quickly abandoned.

Beet pulp was also integrated into senior feeds because of the need for a high-fiber feedstuff that could be ground and incorporated into a pellet. The new generation of high-fiber, low-starch feeds that emerged in the late 1990s was an obvious end-use for such an excellent fiber source. Now, beet pulp is prevalent in feeds designed for all classes of horses.

What are the differences between beet pulp and cereal grains as energy sources?

Horses derive the majority of the energy (calories) in cereal grains from the enzymatic digestion of starch that is absorbed in the bloodstream in the form of glucose. On the other hand, horses derive the majority of the energy in beet pulp from the microbial fermentation of the fiber content, which is absorbed as volatile fatty acids, also known as short-chain fatty acids.

What are the advantages of feeding beet pulp as part of a diet?

Compared to other fiber sources like hay, beet pulp has much more digestible fiber. For example, the digestible fiber in hay is around 40 percent, while beet pulp has closer to 80 percent digestible fiber. The more digestible the fiber, the more calories that feedstuff provides the horse.

Further, beet pulp mixes well into a textured feed and can be pelleted easily. Plus, soaking beet pulp is a way to get more water into the horse.

How does beet pulp stack up to hay as a source of fiber?

The type of fiber found in beet pulp, considered “rapidly fermentable fiber,” is much more readily fermented by the microbes in the hindgut than the fiber in hay or typical forage sources. Hay consists mostly of cellulose, hemicellulose, and lignin. While lignin is completely indigestible, cellulose and hemicellulose vary in digestibility depending on the maturity of the plant.

Beet pulp provides energy, but does it add appreciable amounts of other nutrients?

Beet pulp has higher amounts of calcium than grains, about the level found in typical commercial concentrates. In addition, beet pulp is comparatively high in iron.

Should beet pulp be fed soaked or unsoaked when fed by itself or as part of home-mixed concentrate? 

If feeding beet pulp shreds, they can be fed dry, especially if mixed with other feedstuffs. Free-choice water availability is important if feeding dry beet pulp. Pelleted beet pulp, however, should not be fed dry because it may increase the likelihood of choke. Horses prefer to consume beet pulp shreds soaked rather than dry shreds, probably because it softens their texture. My preference is to feed beet pulp soaked.

Further, one of the advantages of feeding soaked beet pulp is that it is a way to sneak a bit of water into the diet, especially in the winter when water consumption may be down. The Europeans have come up with a method of micronizing and then flaking the pulp so that it soaks quickly, in less than 10 minutes.

Are there any special uses for beet pulp?

Soaked beet pulp is a useful vehicle for holding larger amounts of oil, which is often recommended as a way to get more calories in the horse.

It was thought for a while that soaked beet pulp could help to push sand out of the digestive tract, but research found it ineffective in prevention of sand colic.

Is beet pulp use in the U.S. different than in other areas of the world?

Beet pulp has worked its way into quite a number of commercial feeds in the U.S. Many horse owners feed soaked beet pulp in addition their regular feed.

As the history of beet pulp would suggest, its use is more longstanding in areas such as England, Northern Europe, and Russia, where much sugar beet is cultivated. Because of the climate needed for sugar beet cultivation, South America had very limited sugar beet production, as was the case in Australia and Africa. However, cultivation is expanding to newer areas because of a variety that can be grown in the warmer climates as a winter crop, instead of a summer crop as it is in more temperate climates.  Where beet pulp is not grown, it may be imported and therefore rather expensive.

Get The Scoop On Horse Feed From An Equine Nutritionist

Let's go back in time to 1821—for sake of entertainment, you can be a horse.

You're a drafty fellow, and there are fields to plow, wagons and carriages to pull and the five-day workweek has yet to be heard of, especially for a horse out on the farm. Like the steady workhorse that you are, you're hoofing 10 to 15 hours per day, expending a lot of energy and calories. Your source of food includes grazing low-quality forage (hungry yet?).

Dr. Jyme Nichols, director of nutrition at Stride Animal Health, says this is about the time cereal grains were introduced into horses' diets. The grains most popular and accessible to feed horses included corn, barley and oats. Knowing horses required higher levels of fiber, as it's safest for them and their diet, oats had the highest level of fiber and was a natural choice to feed for extra calories that provided horses with extra energy.

“Fast forward to present day – we have horses kept in stalls or in small turnouts, and they may have very limited hours of riding. That horse that used to work 10, 12 or 14 hours a day now maybe only works an hour a day when we have time to ride them. The rest of the time, they spend eating. But they are still receiving the same concentrated grain meal that we were giving them many years ago when they were working so hard. If you take a high-starch feed like that and overfeed them, you can make a horse very excitable or crazy,” said Dr. Nichols during an interview with Valley Vet Supply.

Equine nutrition is complex – there is no sugar-coating that; however, Dr. Nichols warns there is plenty of “sugar-coating” when it comes to our horse's grain choices, and that along with high starch are just a few aspects to consider relating to our horse's nutritional program.

With insight from Dr. Nichols, let's review top equine nutrition FAQs.

Does my horse need supplements?

The answer to that is never black or white. It depends on what you are doing with your horse; how old your horse is; whether you're feeding your horse a forage-only diet or whether your horse is on feed. It also depends on if your horse is dealing with certain problems, like if they have arthritis, gut issues or specific needs that are outside of what we would consider 'normal,' more basic nutritional needs.

Does protein make horses hot?

No, it doesn't. It is the starch and sugars in what you are feeding that make horses hot. There is some confusion about protein—it's commonly thought that horses need more feed, more protein and more nutrients, so we're going to feed this higher-protein feed. But what owners may not realize, is that when they were feeding that higher-protein feed, they were also feeding more of it. It wasn't necessarily the high protein that was making the horses become excitable. It was the fact they were feeding a really large volume of a high-starch, high-sugar feed.

Nutritionally, how can I manage or prevent a “hot” horse?

If you have a horse that is naturally more excitable and anxious, one of the better things you can do is look for a diet that is high in fiber and pull your calories from fat sources. Those fat sources are called “cool energy calories,” meaning it gives horses the calories that they need, but it's not going to make their mind and their attitude hot and excitable. For energetic horses, avoid high starch feeds. Refer to the feed tag for the “NSC,” which is the combination of starch and sugar. “NSC” stands for non-structural carbohydrates. You get to that number by adding the starch number on the feed tag to the sugar level. As a general rule of thumb for feeds considered “low starch,” if you were to add the starch and the sugar together, that number shouldn't be over 22 percent.

Can sugars impact certain horse health conditions?

For PPID horses or Cushing's horses, starch and sugar are really important in the diet to help manage. If you have a horse with a medical sensitivity, such as a horse with Cushing's, laminitis or equine metabolic syndrome – the medical sensitivity to sugar means you need to make sure that your NSC is under 12 percent. After that, you want to make sure you're feeding at the recommended levels of the feed. If you're not – and let's say that particular feed calls for 6 pounds per day and you're only feeding those horses 3 pounds per day, you're shorting them in important trace minerals or vitamins.

How do you nutritionally manage a horse that ties up frequently?

There is not a generic answer. But keep horses off green grass [which has higher sugar content]; feed low-starch, low-sugar feed; and make sure you have a proper balance of trace minerals, macro nutrients and vitamins. Also, ensure they have daily exercise.

How do I know if my hay is meeting their basic needs?

First off, do a visual check and body condition assessment of your horse. Look at rib cover – you should be able to easily feel but not easily see, ribs. Next, you'll want to look at the topline. You want the horse's topline to be essentially flat. If they can hold water on their spine on a rainy day, that tells you they're in a bit of an excess body condition. But if rain were to pour on them and just run off, and their spine peaks up like a mountain, then that tells you their body condition is probably a bit under. But the most concrete thing you can do is get your hay tested. Getting that information is the most important thing you can do, because forage is the foundation of your horse's diet and it is so important to understand what you are feeding.
