Diatomaceous earth

Happy Horse Healthy Planet_DE Cover

What is Diatomaceous earth and Where does it Come from?

Diatomaceous earth (DE) is the fossilized remains of tiny aquatic organisms called diatoms harvested from the bottom of oceans across the globe. Diatoms are the grass of the oceans and lakes and are the food of water grazers just as grass is the staple food of many land dwelling animals. The diatom skeleton is made of a natural substance called silica.

Silica is very common in nature in various forms and makes up 26% of the earth’s crust by weight. It does not exist naturally in its pure form as it usually reacts with oxygen and water to form silicon dioxide. Silicon dioxide has two naturally occurring forms: crystalline and amorphous. Most Diatomaceous earth is made of amorphous silicon dioxide and this is the one we use for horses.

The beautiful geometric shells of the silica remains form massive deposits of Diatomaceous earth which is mined, milled, and processed into two main types, Food Grade and Industrial grade.

Diatomaceous-Earth-Diatoms-Progessive Gardens

There are a number of products containing Diatomaceous earth that are used for pesticide purposes. You’d be surprised at the number of non-pesticide products that contain Diatomaceous earth including skin care products, toothpastes, foods, beverages, medicines, paints, and water filters.

Anything ingested or used around animals is always Food Grade DE which is non-toxic, safe and crushed to a fine powder sometimes sold as “Fossil Shell Flour”.


Food grade Diatomaceous earth products are purified and even allowed by the USDA on organic food labels. Food grade DE is used as anticaking materials in feed, and as clarifiers for wine and beer. It is also used as a mineral additive, for detoxification, and as an effective insecticide.  This photo of the DE, magnified 7000 times, looks like spiny honeycombs that resemble bits of broken glass.


What is the Value of DE in Equine Nutrition?

When the diatoms are mined and ground up it ends up as a powder that looks and feels like talcum powder. When added to feed your horse will get the benefit of valuable trace minerals that make up Diatomaceous Earth. DE is approximately 3% magnesium, 33% silicon, 19% calcium, 5% sodium, 2% iron and many other trace minerals such as titanium, boron, manganese, copper and zirconium.
The most common nutritional benefit of DE for horses is parasite control but many horse owners report added benefits such as better coat and/or hoof condition.

As every horse owner (should) know parasites can wreak havoc with equine health. Internal parasites interfere with the absorption of food, cause weight loss, colic and diarrhea.


External parasites cause skin infections and an enormous amount of stress to your horse.

With a good internal and external parasite management program your horse will see an improvement in health, appearance and behavior, as well as assimilation of feed, which means improved weight gain and lowered feed cost.

In my experience Diatomaceous Earth is a fantastic natural pesticide that deters all manner of insects that torment our animals. DE shows no indication of mechanical or chemical damage to the animal tissue therefore it can fed to the horse as a step in controlling internal parasites. DE can also be used as a dust for external pests by rubbing into the coat of the animal.

Food grade Diatomaceous earth is a great way to address parasites in your horse, but you should not rely on it as your only form of defense. Controlling intestinal worms in horses is a many layered endeavor that includes other Best Management Practices. Rotating pastures, appropriate pasture stocking rates, new horses being introduced to the herd appropriately, manure management and type or number of parasites needing to be controlled, are all parts of a good equine pest control plan.

How Does DE Work?

We don’t normally think of bad things as “positive” but when it comes to the way DE works, we do. The silica in DE is a semi-conductive mineral which when warmed by body heat becomes negatively charged. When this happens it gives off electrons that attract and absorb positively charged (but bad) things that are small enough to go through the holes. These positively charged things can be bad microbes, free radicals, and other positively charged waste.

Because of the strong charge, each shell can absorb a large number of positively charged substances, whether they be chemical or in the form of bacteria or viruses. After attracting these positively bad things, DE passes through the stomach and intestine, escorting these harmful substances out of the body.   Other larger parasites that can’t fit through the holes are “cut up” and killed by the sharp edges of the DE. Don’t worry though; the DE does NOT kill the beneficial bacteria in the gut nor “cutup” the intestinal lining.

Healthy Microbes Are Safe

When Diatomaceous earth is eaten, very little is absorbed into the body and the remaining portion is rapidly excreted.  Small amounts of silica are normally present in all body tissues so it is therefore normal to find silicon dioxide in urine but some studies looked at whether this would increase with the addition of DE to a diet.  These studies have shown that horses fed DE had no difference in silica amounts in urine samples as the silica in the DE was excreted .

How Do You Feed it to Horses?

If you decide to add DE to your equine management program make sure you purchase a product labeled as food grade or medical grade. These forms will be free of any contaminants or unwanted additives. Avoid the crystalline form of silica, commonly used in swimming pool filters, as the beneficial properties have been changed and other chemicals may have been added.

As each horse is an individual you should cater your DE amounts to several factors; weight and worm count.

Different Doses

Different Doses

You will need to cater the amount according to body weight as you would the dosage of any wormer. The suggested rate of food grade DE for a 1,000 lb horse is 1 cup a day. Remember, you need to feed it according to what each horse’s worm count demands; higher worm count in a particular horse = higher dosage of DE for that horse.

A minimum of 60 days is suggested for best results, you should re-check the fecal count at 30 days to make sure you are using enough. If fecal counts are not low after the 30 day re-check increase the daily dose of DE. Feeding too small a dose of DE will not give desired results.

Many horse owners just keep their horses on DE as part of their daily ration. In these cases some horses only need a 1/2 cup of DE daily, while others might need a full cup, but I have heard of horses staying worm free on as little as 2 cups per week. As I said before, each animal is different so cater the amount to the animal.
DE does not have an offensive order or taste so you can mix it with water or juice and feed it as a paste, or mix it directly into your horse’s feed. I would still add a bit of water to the feed to keep the dust factor at a minimum.

Diatomaceous earth
If you are like me you like to keep your horse supplements to a minimum so I use products with additional ingredients that address multiple concerns. There are two DE products I like that have additional benefits. Bug Lyte contains brewers yeast, thiamine, grape seed extract, garlic, niacin, and Diatomaceous earth. NHD Natural Wormer contains slippery elm, kelp, juniper berry, cascara segrada, clove, sage, garlic, and Diatomaceous earth.

Are there Any The Risks With Using DE?

As long as you be sure to use food grade DE you are fine. Food grade Diatomaceous earth is EPA approved to be mixed with grains and used against indoor and outdoor crawling insects. Food Grade DE is USDA approved as an anti-caking agent for animal feed and it is FDA approved for internal and external use. So all the safety agencies confirm that it is nontoxic when used appropriately.

The biggest risk is using the wrong grade of DE so pay attention to which grade of Diatomaceous earth you buy. Industrial grade Diatomaceous earth is mainly used for pool filtering. It has been through heat and chemical processing and is highly toxic if ingested. So it is REALLY important that you only use food grade Diatomaceous earth.


If you haven’t wormed in a while, or have a horse with an extremely high egg count, I encourage you to use a slow introduction to Diatomaceous earth to avoid a detox reaction from a rapid killing of parasites and worms.

There is also some concern about what DE could do to a horse with ulcers or other digestive issues. Personally, I would not want to introduce anything more to an already compromised digestive system so I generally recommend that clients NOT use DE with these horses.

Be sure to consult your veterinarian before switching to a regular DE program, most vets are on board with fecal counts but can be in to a more chemical approach for paarasite control so be prepared for this.

A few other cautions. Some say it is better to use DE it in the morning, as it has been known to elevate energy levels. Also, I have heard of people withholding food from their horse before worming. With DE, or any wormer, you should never “fast” a horse, an empty equine stomach = trouble. Finally, if you are applying DE as a dust externally, use a face mask and apply with a bulb duster.


In Summary:

Many horse owners love the to use Diatomaceous earth topically to dry out wet stalls and to fight the flies manure attracts. The most controversial use of Diatomaceous earth is as a dewormer, but I have found it to be effective and safe.  I incorporate DE into my multifaceted deworming program, which includes a bi-annual fecal flotation test, but remember, DE should not be your only means of defense against internal parasites. Incorporate other Best Management Practices into your program to ensure control.

Peace and Good Feed,

Chinese Herbs For Horses

Happy Horse Heathy Planet_Herbs for Horses

I could have put this article under the letter “H” for herbs but I found that most of the horse owners I meet that use herbs do so because they believe in Traditional Chinese Medicine (TCM) and its philosophies. Therefore, it is the final installment under the letter “C”.

Have you ever wondered what Chinese herbs are doing in equine health care? Are you a bit confused by all the herbal products out there and their purpose? Well, this article will help you understand the role that Chinese herbs have in equine best management practices.

In my personal health and horse management program I like to use an integrated approach that combines the best of traditional medicine (and methods) with alternative ones. I have found that this combination helps me find solutions to stubborn problems and results in a more holistic system of care.

Chinese herbs can be used for a multitude of problems including long term issues such as allergies, arthritis and immune support. They can also help with more short term problems such as anxiety and digestive upset.

I suggest you consider using herbs and herbal blends if you want a more natural approach or as a compliment to more traditional methods of horse care.

What are Chinese Herbs and Where Do They Come From?

The use of both Chinese and Western Herbal medicine dates back thousands of years. It aims to understand and treat the underlying causes of disease and ill health rather than just focusing on the expression of symptoms, thus it is a very holistic form of medicine.

For centuries the Chinese theories have offered herbal solutions that support health, not by simply addressing the issues, but by balancing the body’s underlying disharmony. Chinese medicine can be defined as a philosophical theory based on Yin and Yang and the Five Elements related to health. Most horse owners that use Chinese herbs do so based on these traditional Chinese theories of health and wellness.


Chinese herbs are classified and used based on a physiological effect (what it does in the body), by the meridian and/or organ system affected, by their taste (bitter, sweet, etc) and by their temperature. This system is unique to the practice of Chinese herbalism. Of the 6,000 documented medicinal species, 400 are used regularly, mixed, matched and paired based on a desired effect.

Horses are herbivores so they eat plants. In their natural environment, horses graze and they readily consume various herbs. Horses will naturally eat herbs such as Comfrey, Red Clover and even wild Garlic when they are available.

However, not all useful herbs grow in the pastures of domesticated horses since each require differing climates to be at their best. Therefore, many horse owners supplement herbs in the diet of a domestic horse.

Some suppliers use only the best quality herbs that are sourced individually from specific Providences of China. They believe the climate and quality of the soil combine to provide a far superior growing environment to anywhere else on the globe.

No matter the source, using herbs is more of a thought process and wellness attitude than of a geographical area of origination as there are many herbs that come from all over the world.

Many equine Chinese herbal blends are the by-product of the human herbal industry where they are ground or pelletized for use with horses.

I bet many of you drink herbal tea. The tea in the bag looks nothing like the plant it originated from. For example, this is what the chamomile plant looks like

In addition, many of our modern drugs originate from herbs, for example, aspirin comes from white willow bark.

Why Feed Chinese Herbs To Horses?

In the wild horses have access to hundreds of herbs and plants and when fed responsibly herbs can provide domesticated horses with a variety of health benefits.  Generally speaking herbs are used for chronic, long-standing problems and often can allow your vet to reduce the amounts of pharmaceutical drugs they use on your horse.

Traditional medicine uses a very linear approach; this is the problem and this is the solution. Sometimes because of this non-holistic view, modern pharmaceuticals can weaken the body in one area while addressing the symptoms in another.

To me Chinese herbs are more suited to overall general health than acute illness.  Chinese herbs are a beneficial additional form of nutrition from a source other than good quality feed to keep horses at a noticeably higher level of health.

They are also a great aid in the healing process after traditional medical treatment has addressed the immediate threat. For example, treating an ulcer should begin with a traditional pharmaceutical acid reducer such as omeprazole, but long term healing and prevention can be supported through herbs such as slippery elm and licorice root.



In fact, the most common reasons I see for horse owners to use Chinese herbs are for long-term help with calming, boosting the immune system and for digestive issues such as ulcers and colic.  Herbs can sometimes do things that pharmaceutical drugs cannot like balancing hormones and often herbs can have a better safety margin than traditional medicines.

Chinese herbs can promote health without the negative side effects that synthetic vitamins can produce such as taxing the body’s elimination organs.  Some herbs are also more readily consumed into the body because horses find many of these plants more palatable than traditional supplements.

How Do You Feed Chinese Herbs to Horses?

Chinese herbs are normally safe and effective, but they must be used thoughtfully and intelligently. As with any supplement, prior to feeding any herbs to your horse always check with your veterinarian to be sure there are not any medical concerns. Some herbs should not be fed if your horse is pregnant or has been diagnosed with an illness like Equine Metabolic Syndrome for example.

Before you even consider adding herbs to your horse’s diet I would also suggest that you get a book on herbs for horses or at least do some internet searches to familiarize yourself with herbs and their uses.

There are over six thousand different plants that are used in herbal supplementation.  Chinese herbs can be used alone or in a blend but which ones work best in various combinations can be confusing. You should determine what your goal is as each herb has specific uses.

To correctly dose your horse, even for basic herbs, you still need to take into consideration the variables such as size, current health, nutrient profile of its ration and use. As with traditional medications, each horse will have specific dosage and requirements.

Different Doses

Different Doses

Most horse owners I work with feed a prepared herbal supplement that has been formulated by professionals that understand the correct combinations of herbs and that provide recommendations on usage. This can take some of the guess work out of feeding herbs.

When developing an equine herbal formula, the Chinese herbalist is much like a cook in the kitchen. The Chinese herbalist combines various herbs based on their contribution to create an effective formula designed with a specific health goal. A cook combines various ingredients to develop a well-balanced meal.

HappyHorseHealthyPlanet_UC Herbal Blend

I advise owners not to overload or overwhelm horses with too many herbs, supplements and medications simultaneously. I would suggest that you limit the use of herbs to two formulas at any time so you can better evaluate the results.

It’s also important to know that the herb manufacturer has good quality control procedures and backs up their products. Only use products with the ingredients listed on the packaging so you can be sure you are feeding the herbs you want.

Start slowly and give them time. Chinese herbs work slowly unlike traditional medications that generally show improvement within days.

Are Chinese Herbs Safe To Use on my Horse?

Because herbs are considered dietary aids or nutraceuticals they are not well regulated by the FDA.  Although they are considered generally safe, they do have a physiological effect on the body and should be used wisely.

Always speak to a vet (preferably one who’s open to and somewhat knowledgeable about nutraceuticals) before administering any herb to your horse. Never use herbal preparations in place of veterinary care. It’s important to get a proper diagnosis FIRST as with any treatment, you need to know the cause of the problem before you begin treating it.

For example, your horse’s poor coat condition could be from mineral deficiency or parasite infestation. If you just start feeding an herbal supplement to improve the coat, you could create a new problem without ever addressing the original one.


Poor Coat could be Parasites

Many horse owners assume that because an herb is “all natural” it is always safe. You must remember though that Chinese herbs act like a drug in treating a condition and like a prescribed drug have specific properties and can have side effects. Remember that some herbs may be contraindicated for your horse if you use them with other drugs or other herbs.

In researching Chinese herbs use a variety of sources, I always feel that if I find multiple sources agreeing I feel more confident in its accurateness.

Remember, just because a little is good doesn’t mean a lot is better! Discuss your plans with your vet, an herbalist or use one of the many herbal blends and FOLLOW PACKAGE DIRECTIONS.

Corn in the Equine Diet

Happy Horse Healthy Planet_CornWhat is it and where does it come from?

Corn, or maize as it’s known in many parts of the world, is a large grain plant domesticated by indigenous peoples in Mesoamerica in prehistoric times.  It constitutes more than 80% of the grain fed to animals in North America and, when fed correctly, it is a good-quality and nutritious grain for horses. Corn is grown in almost all states in America and is readily available to horse owners.

The leafy stalk produces ears which contain the grain, which are seeds called kernels. Because Corn is a hull-less grain, however, it is very high in starches.

Corn grain is a major feed grain and a standard component of livestock diets where it is used as a source of energy.
