Teacher: Class, does anyone know what “all-natural” means?

<Courtney and Elissa raise their hands>

Teacher: Anyone besides Courtney and Elissa?

Teacher: Anyone?

Teacher: Fine. Go ahead…

Courtney: Anyone who knows their way around a grocery store can tell you what “all natural” means (hint: basically nothing). Unlike certified organic foods, which are strictly regulated by the USDA, there is little regulation that determines what can be included in foods labeled “all-natural.”

Elissa: By the USDA’s standards, items deemed “natural” should be minimally processed and without artificial ingredients or preservatives. However, antibiotics, growth hormones, and mystery chemicals are fair game, and there are no inspections to legitimize product claims. Interestingly, the term “all-natural” technically isn’t regulated by the USDA at all.

Teacher: Right. Reading the nutrient information on human foods has become pretty commonplace, but some label lookie loos who are interested in keeping their own diets so-fresh-and-so-clean are beginning to keep an eye on what goes into the feed of their animals, as well. Does anyone know what it means to feed a horse a truly all-natural diet?

She is a frequent guest speaker at the UC Davis School of Veterinary Medicine, and currently teaches Equine Health at Cosumnes River College. Dr. Thunes understands the vital role that nutrition plays in managing horses, and believes in making nutrition accessible to everyone. By removing the guesswork, owners have peace of mind knowing that their horses’ diets are optimized for maximum health and peak performance.

This week, she explains a bit about the natural equine diet, and answers all the questions we couldn’t.


What exactly does all-natural mean as it pertains to horses, and is it safe?

As a term, all-natural does not mean anything specific, as the term is not recognized or regulated by the USDA. When we think about this term in relation to feeding horses, most would probably agree that it means feeding them a diet as close as possible to the type of diet that they evolved to eat, which means a forage-first diet.

Some commercial feed brands are making an effort toward more natural ingredients, or less processed techniques. What do you currently see being done, and is it a good start?

For a number of years now, the major feed manufacturers have been reducing the starch and NSC content of their feeds, relying more heavily on sources of fermentable fiber and fats as energy sources. While the natural diet of the horse is not particularly high in fat, they do digest fat well and it is a safer way to feed them extra calories when needed than relying on starch. More recently, some manufacturers have started to offer feeds with non-GMO ingredients.

Does a more natural diet mean a DIY preparation of meals, or a combination of commercial options with supplements?

A more natural diet means starting with good, clean forage and relying on this as the foundation of your nutrition program. From there it is a matter of adding what is missing from that diet, depending on each individual horse’s needs. This might mean the addition of a higher calorie feed if the horse is struggling to maintain condition on a purely forage diet, or it might mean just adding a source of vitamins and minerals that are commonly missing in the forage. Some owners will prefer to achieve this in a more DIY fashion, and until recently, if you wanted to follow the more natural approach, that was really your main option. However, with major feed manufacturers starting to embrace more natural approaches such as non-GMO and the availability of USDA certified organic feeds, there are now more options for those who want a little more convenience.

When reading labels, what are some of the “least attractive” ingredients of which we should be mindful in commercial feeds today?

Some of the ingredients that are perceived as unattractive are in fact misunderstood. Those who subscribe to feeding “all-natural” tend to be anti-by-products, as these ingredients are the result of processing a commodity for some other purpose. For example, beet pulp is a by-product of the sugar beet industry. While it is a by-product, it has a very useful purpose as a fermentable fiber in feed, providing calories in a form that requires microbial fermentation in the horse’s hindgut, a process that honors the horse’s digestive anatomy and physiology. Including beet pulp in feed allows feeds to reduce starch, creating a diet that relies more heavily on fiber, which is a good thing.

Another example is wheat middlings. Often considered to be the sweepings off the mill floor, they are in fact the by-product from the milling of wheat for flour. As the demand for lower starch feeds has increased, feed manufacturers have had to turn to ingredients that have lower starch but that still maintain the overall calorie intake of the feed. This is where wheat middlings come in, because they have a starch content in the low 20 percent range, whereas straight grains have starch values of over 40 percent. So while processing of ingredients is often frowned upon by those who want to feed all-natural diets, processing can be a very good thing.

What are the more natural ingredients/alternatives we should consider instead?

For those who are concerned about using natural ingredients for their horses, rather than avoiding certain processing techniques or by-product ingredients that can bring a lot of value to the ration, look for those ingredients from non-GMO or certified organic sources.

Can you give us examples of more natural ingredients we could be looking for that address the basics like protein, fat, carbs (NSC and fiber)?

When forage is the majority of the horse’s diet it will provide adequate fiber and also most of the horse’s protein and carbohydrate needs. However, protein quality may not be optimal and additional sources may be needed. Ingredients such as field peas, canola meal, flax and alfalfa can provide additional sources of amino acids. Carbohydrates in the form of starch are most easily provided by feeding whole oats, although this would not be appropriate for horses with metabolic issues. Flax, sunflower seeds, copra meal (coconut meal), as well as oils such as camelina, are all sources of additional fat.

Then there are all of the vitamins and minerals…how do we ensure we aren’t robbing our horses of the essentials?

It is important to make sure that the diets we are feeding are properly fortified at a level to meet the horse’s daily requirements. This is especially true for the trace minerals zinc and copper, which are often deficient in forage based diets. Vitamin E levels should be tested through blood work to determine whether additional supplementation is required, as this is another nutrient that is often lacking, especially when the diet relies heavily on hay.

And, naturally, how does one transition off of commercial feed to a more natural regimen?

There is no special way to transition to a more natural diet. As with any diet change, it should be done slowly over a period of at least 7 to 10 days. This will allow the digestive tract time to adapt to new feed ingredients, and helps to reduce the risk of colic.
