ALFALFA
Horse people tend to go to extremes when it comes to this legume -- they either want to ban it from their horses' diets completely, or feed their horse nothing but alfalfa.
One of the most mineral-rich foods known, Alfalfa has roots that can grow as far as 130 feet into the ground. It contains powerful digestive aiding enzymes and it is one of the most bio-available sources of calcium for horses. This is very helpful in balancing primarily grass hay diets -- which tend to fall short of calcium.
But some horses go laminitic on Alfalfa. It's sugar profile is different than grass hays; Alfalfa contains more glucose. For sensitive horses, even small amounts of alfalfa can cause inflammation.
So what is a horse owner to do about alfalfa?
Know your horse! If you do not supplement with alfalfa, you may need to supplement with calcium. If you do try to supplement your horse's diet with alfalfa, start of with a very small amount -- a handful. Then slowly, over a period of a week or two, work your way up to 2 pounds per day. Try weighing the amounts you feed on a bathroom scale. You may be surprised at how little alfalfa two pounds actually is.
ADAPTOGENS
Adaptogens are exactly what they sound like -- substances that helps the body adapt. Adaptogens help to normalize body functions during times of stress.
Cushings and Insulin Resistant horses can be stressed more easily than "normal" horses because their metabolic conditions can compromise their ability to handle internal as well as external fluctuations -- i.e. seasonal and weather changes. This difficult adapting to change creates a detrimental domino effect inside the horse's body, which is trying to return to a state of balance but needs some help! This is where adaptogens come into play.
Two of the most widely used and clinically proven adaptogens for Insulin Resistant horses include the powdered Chinese herb Raglan, and the synergistic blend of herbs found in Advanced Protection Formula (these herbs include Eleutherococcus senticosus, Rhodiola rosea, Schizandra chinensis and Echinopanax elatus).
Jiaogulan means "Strong hoof" and specifically targets increased circulation in the horse's feet. It is therefore extremely beneficial to horses who suffer from chronic abcesssing and/or laminitis. The herb also lowers blood sugar levels.
APF helps to boost a horse's energy levels, especially during times of disease. It has helped to snap many a horse out of laminitis. It is also a very good tincture to increase the appetite of a Cushings horse. To find product information on APF, click here.
While adaptogens can be a wonderful addition to a horse's nutritional program, they are not "magic bullets." If the foundation of a low sugar/low carbohydrate diet is not in place for an Insulin Resistant horse an adaptogen will not help.
ANTIOXIDANTS
This is a substance that blocks or inhibits destructive oxidation reactions. Vitamin C and E, and the mineral selenium is a powerful anti-oxidant. Horses need anti-oxidants to help them heal. This is particularly important when a horse is recovering form laminitis or the degenerative effects of Cushings.
However before buying one of the many an anti-oxidant supplements available, it is important to note a few facts about Vitamin C:

* Vitamin C increases the absorption of iron.

* Iron is an inflammatory and is often found in excess in

grass hays and pelleted foods (because of the machinery that

processes the pellets).

* In clinical trails of Insulin Resistant horses, most I.R. horse

were found to have significant iron-overload.
Therefore, it is almost always a good idea to resist supplementing with Vitamin C in metabolically challenged horses, and instead supplement with Vitamin E. (Please see the section on this page on Vitamin E.)
Other natural and very powerful anti-oxidants include the mineral selenium and organic and/or pesticide-free herbs. Selenium supplementation must be done with awareness of the selenium deficiencies or excesses in your area. Please do your research, as selenium toxicity can be lethal to your horse.
BEET PULP
Beet pulp can be a good food to add to your horse's nutritional program if it is prepared with care and the horse owner takes the necessary time to ensure this care -- i.e., the beet pulp is rinsed before it is soaked. To read more about this food that is neither a forage nor an energy feed, click here and scroll down to the June 4th entry titled: The Worries and Wonders of Feeding Beet Pulp.
FLAX
Flax is an essential fatty acid. Horses get their essential fatty acids from live grasses. However most Insulin Resistant horses can not tolerate enough fresh grass to get their EFAs. So the nutrients need to be supplemented.
I have learned about flax and its facts almost exclusively from Dr. Kellon and so I will quote her directly on this subject:
"Essential fatty acids are fats that must be present in the diet because the horse cannot manufacture them.
A horse eating fresh grass gets generous levels of omega-3 (anti-
inflammatory) and much less omega-6 (inflammatory pathways). Horses on
hay alone or hay and grain get a reversed intake because omega-3s do
not survive the curing process and all common grains and seeds are high
in Omega-6, and low in Omega-3.
The EFA requirements for horses have never been studied so I'm going by
what the profile is in their natural diet - fresh grass. This is a
ratio of at least 4:1 omega-3:omega-6. Flax fits that profile."
Remember that even something as wonderful as flax can be fed in excess, especially to Insulin Resistant horses who need to have their dietary fat intake kept in close check. It is often recommended that an average horse receive between 4 and 6 ounces of flax per day. You can buy a very high-quality stabilized flax called Omega Horseshine or you can buy the whole seed at a feed store and grind it in a coffee grinder. Just be sure to feed it fresh as the ground form can turn quickly rancid.
GRASS HAY PELLETS
Grass Hay Pellets can provide a wonderful way to mix your horse's supplements and herbs in his daily rations. However, for I.R. horses it is important that you make sure you check out the manufacturer's feed label to note whether the pellets carry a guaranteed Non Structural Carbohydrate analysis of 10 percent or less. This is very important -- there are feed companies who are unscrupulous with their marketing and who will claim something is "lite" or "low" when in fact the numbers are above the suggested 10 percent.
Once you have the NSC nailed down, try also to find out whether or not the pellets contain added fat -- which is bad for I.R. horses -- or added fillers -- which is unnecessary as well as unhealthy.
Then look for high iron content. Iron is an inflammatory that is not good in excess for I.R. horses (or any horse). Unless a company goes out of its way to minimally process its pellets, it is difficult to find hay pellets -- or any pelleted feed for that matter -- that is acceptably low enough in iron for an Insulin Resistant horse. Part of the reason for this is that the machinery used to process the pellets is metal and metal is high in iron. Horse need only 40 ppm of Iron a day.
PRE AND PRO BIOTICS
The word probiotic is derived from the Greek language and means "for life."
A probiotic is an organism that encourages the growth of beneficial bacteria.
A prebiotic helps to sustain the life of the probioitic organism.
The term synbiotic is used when the product contains both pro and pre biotics.
Horses in stress often need pre and probiotics, and it is my experience that horses who have undergone extensive drug therapy, particularly those involving NSAID's, can benefit greatly from these organisms.
A very good probiotic and one which contains live probiotics and is available in most feed stores is Pro-Bios Equine Gel.
A powerful whole food that acts as a prebiotic is Slippery Elm. I have had very good effects with feeding a large handful of the cut and sifted herb drenched in chamomile tea. An added benefit of Slippery Elm is that it has a lot of fiber.
Horses with healthy gut function and strong intestinal flora do not need probiotics on a regular, ongoing basis.
SALT
A horse's salt-water ratio is essential to the horse's hormonal regulatory system, his function of his heart, his metabolism -- and therefore his very life.
It there was only one sentence I could write about horses and salt it would be this: Your horse probably needs more salt!
The average horse who is not exercising or sweating needs at least approximately one ounce of salt per day. Most people "free-choice" salt and leave it at that. The problem with this is that many horses do not eat enough of their salt blocks to meet their dietary/hydration/electrolyte needs. Consider that a single horse would need to consume a salt block every month to be getting enough salt to meet his minimum requirements.
Appropriate hydration of your horse requires replacement of water as well as salt. But herein lies the dilemma: If your horse is not getting enough salt, than it is likely not feeling thirsty enough to drink enough water!
So unless your horse is avidly chowing down on his or her salt block, feed at least an ounce of salt per day.
"Force feeding salt" is something you will not be able to do in large amounts. In fact, getting a horse to eat a meal with "too much salt in it" can be impossible. Therefore, go slowly and feed more frequent meals to ensure salt intake.
One more thing. This is one realm where the word "organic" makes me cringe. The reason: "Processed salt" is actually cleaner, purer salt, as all the dirt has been removed leaving nothing but pure, sodium chloride (NAC1). Organic salt has other minerals because it still has dirt on it. Remember, dirt is a compilation of minerals. So while it may sound good to say you are feeding your horse organic salt, all you are doing is feeding sodium chloride with dirt.
* Important: Please be extremely careful to differentiate between the intake of salt and iodine. Both are different and both are critical and must be fed in adequate amounts. Excesses in iodine can easily lead to toxicity. Unless extreme overdosing occurs, salt is excreted through urine.
MINERALS
Every living cell and therefore being on this planet depends on minerals for its existence.
Minerals are naturally occurring elements present in the earth's rocks and soil. These nutrients are used by plants, which Herbivorous animals -- such as horses -- then consume.
There are two kinds of minerals: Major minerals (also known as bulk macro minerals) and trace minerals (known as micro minerals).
Major minerals are required in larger amounts than trace minerals and include calcium, magnesium, sodium, potassium and phosphorous. Trace minerals, though required by the body in smaller amounts, are every bit as critical as major minerals. Trace minerals include boron, chromium, copper, germanium, iodine, iron, manganese, molybdenum, selenium, silicon, sulfur, vanadium and zinc.
Metabolically challenged horses need careful attention paid to the balancing of their minerals, especially magnesium, selenium, copper and zinc, as these nutrients play critical roles in muscle function, cartilage development, the utilization of fat, the absorption of insulin and the overall health of your horse's immune system!
Balancing your horse's diet requires knowledge of what your horse is actually eating. This means you need to know what is in the hay you are feeding your horse. The only way to know what vitamins and minerals are in the hay you are feeding is to have a specific or regional analysis taken of the hay itself. This may sound overwhelming but it easier than it sounds. Your local department of agriculture may be able to provide a regional analysis at no cost, or minimal cost to you.
If you are lucky enough to have your own hay barn or access to one, testing a supply of hay will cost you less than $50, including charges to mail in the hay for analysis. Contact Dairy One Forage Labs for complete information.
After you receive your analysis -- a process that takes about a week -- you will have the information you need to provide your horse's with his basic nutritional needs.
NRC DAILY REQUIREMENTS FOR MINERALS FOR AN AVERAGE 1,000-POUND HORSE
Protein: 630 to 699 grams

Chloride 40 grams
Lysine 20-30 grams


Iron 400 mg to 450 mg (40-45 ppm)
Calcium 20 grams


Copper 100 mg (10 ppm)
Phospohorus 14 grams

Zinc 450 mg (45 ppm)
Potassium 25 grams


Manganese 450 mg (45 ppm)
Sodium 10 grams



Selenium 1mg (.1 ppm)




* The Importance of Balance:
High Zinc levels can inhibit the absorption of Copper
Adequate salt levels can increase the absorption of calcium
High Iron levels can interfere with zinc and other mineral absorption
URBAN MYTHS ABOUT MINERALS
It is true that some organic minerals are more easily absorbed. One such example is selenium. However that does not mean that the organic form of a mineral is safer to consume. In the case of selenium, the more available the form of selenium the more easily the horse can be overdosed. So know what is missing in your soils and thus
your hays so that you can feed accordingly.
* Soils have not become depleted of minerals! Soils are minerals. In fact they are the result of rock and stone and other elements ranging from feces, bones, blood, leaves, trees, etc, decomposing into tiny fragments, the basis of which is soil. This is a process that can take millions of years.
VITAMIN E
Vitamin E includes eight antioxidant compounds consisting of four tocopherols (alpha, beta gamma and delta) and four tocotrienols (also alpha thorugh delta). As an antioxidant, Vitamin E prevents cell damage by inhibiting the oxidation of fats and the formation of free radicals. Cut and cured hay have lost virtually all substantial amounts of Vitamin E.
To restore this antioxidant to your horse's diet, feed the d-alpha-tocopherol form -- the most potent and easily absorbed form for our horse. (It is more available to your horse than the synthetic forms.)
Recommended doses for horses who are not on grass average about 2,000 I.U.'s a day. Human gel caps are easy to to administer (they melt in the hot water of a hay pellet mash) and are very inexpensive when bought in bulk at Wallmart or Costco.
WHOLE OATS/GRAINS
Most domesticated horses who are not in hard work do not need grain. Insulin Resistant horses not in work, especially do not need grains, as grains are a high-glycemic food that can quickly put an Insulin Resistant horse into an acute case of laminitis. So for some horses, yes, steer clear of grains. However some horses really do need their oats!
There is fast-growing evidence that hard working horses and particularly hard working Insulin Resistant horses, need the simple carbs contained in grain after exercise. This is because after exercise muscles are glucose hungry and glucose is taken up very quickly by muscle tissue. Insulin Resistance impairs the ability to get glucose into muscles. Small, carbohydrate dense meals given within the first hour of exercise can provide much needed fuel to all hard working horses.
Please do not read this and automatically begin feeding your metabolically challenged horse oats. Start very slowly with the addition of oats to your horses' diet, be careful to include the rinsed and soaked beet pulp (its extremely low glycemic index and acetate composition makes a good mix with the oats) and feed within the one-hour time frame.
