Jini’s Equine Supplement Regimen

horse-lookingDTI’ve written a lot about individual vitamins and minerals that horses need on this blog, and about probiotics and low-sugar hay. Lately I’ve been asked by a number of different people to pull everything together into one list – so here it is!

I approach equine supplementation from a different angle than most horse owners – because I’m also a health writer and I formulate supplements for humans. One of my human supplements is an elemental diet shake that contains over 40 different ingredients and sells into 60 different countries. So when I’m looking at health and supplementation for horses, I go a lot deeper into source materials, co-factors and the form of each substance, than your average horse owner.

Thus far, I’ve spent about 3 months researching pretty intensively into equine nutritional requirements; minimums versus therapeutic doses, and also testing different things on my horses. Because, at the end of the day, you could have a fantastic supplement, but if your horse won’t eat it – because of the smell or taste – then there’s no point in purchasing it.

In this article, I’m just going to give you the straight list of what and how I feed and supplement my horses. The WHY and research behind each item would comprise an entire eBook of information, but Dr. Juliet Getty has already written a comprehensive book, so just go get hers if you want the science.

LTYH Equine Supplement Regimen

  • 2 cups of pure alfalfa pellets (no grains, just alfalfa)
  • HorseTech High Point Grass vitamin/mineral in powder form
  • 1 teaspoon Himalayan or Redmond’s salt
  • 2500 mg magnesium
  • 1 tablespoon seaweed powder
  • Cold-pressed sesame, or safflower, or flax oil drizzled over top – as much as horse will eat, up to 1/4 cup. OR freshly ground flax seed or chia seed.

1-3x/week also add:

*All dosages are given per 1100 lb (500 kg) horse. Sometimes I will add a scoop or two of dried loose herbs as needed, from time to time to assist in liver function, detox, immune system, respiration, etc.

If you don’t want to make up your own dried herb blends, then Wendals Herbs produce excellent quality blends – and yes, I spent hours researching this too!

I really like using pure alfalfa pellets as a base for supplementation, since alfalfa contains the amino acids that are missing from grass and hay. Being a legume, alfalfa enables your horse to actually utilize all the protein in their grass or hay by completing the amino acid profile; thereby ensuring absorption/utilization. Flax seed and soy can also be used to provide complete proteins for horses, which is essential to ensure your horse is not suffering from chronic protein deficiency. Remember, whether human or horse, the body cannot use protein unless it has all the essential amino acids. This is why vegetarians also need to be careful about combining proteins, to ingest the full spectrum.

High Point Grass comes in both loose powder and pellet form; the amounts of each vitamin/mineral are different in each – but always in the correct ratio. For the first few years, I was not feeding any other grain, beet pulp, or pellet feed, so did not have anything to sprinkle the powder form onto. So I purchased the pellet form, which has an alfalfa base (but unfortunately, also contains some wheat).

When my herd grew to 11 horses, it was prohibitively expensive to ship so many bags of the High Point Pellets, so I found a pure alfalfa pellet locally (no filler, grains, wheat etc) and then sprinkled the High Point powder on top of that. We also continued to drizzle cold-pressed flax oil over top, along with extra magnesium, salt (the High Point Grass only contains approx. 1 teaspoon of salt, which is not enough to balance our pasture grass) and then seaweed powder. Sometimes I would include freshly ground flax seed or chia seed as well.

With the larger herd, I also switched to giving the Natren probiotics only once per week, or only when needed (during worming, or immune challenge, or when the horses asked for it).

Do I supplement daily?

For my herd, their supplementation schedule changes with their needs. I think the frequency of supplementation should depend on:

  • Your horse’s current health, age, or health challenges – growing horses and elderly often need more supplements to thrive.
  • The condition of your horse’s coat, hooves, teeth, mane & tail – this is where deficiencies will show up first.
  • Your horse’s living conditions – does your horse have varied terrain to forage a variety of plants? Wild horses consume 25-30 different plants per day.
  • Your horse’s immune challenges – what is your frequency of chemical worming, vaccination, etc?
  • Your horse’s stress levels – are they in a safe, bonded herd group? Do you ask them to compete? Do you ride (so they’re carrying/balancing extra weight)? Do you ask them to do things they don’t like to do? Do they have freedom of movement, or are they confined to a stall/paddock?

When I first got my wild horses, I would supplement them daily until they were no longer malnourished, deficiencies were resolved and their hooves and coats looked good. After that, I would supplement 3x/week.

Here’s one of my wild mustang mares – her filly is a year old, so she is also still nursing. She hasn’t been brushed (didn’t want to be touched yet) but you can see the shiny condition of her coat, and her mane and tail have also thickened and grown longer:

Kaliah after a year under my care

And Kaliah’s yearling filly also looks healthy and is growing well:

Xadaa, 1 year old

My horses have 33 acres of varied pasture and forest to forage in. They eat a lot of plants and trees, rather than just grass. In fact, they will often eat bark, leaves, fern tips, and other shrubs before they will turn their attention to the grass. They are not ridden, or asked to perform. They have 24/7 access to low sugar hay in slowfeeders, year-round.

Once the wildies’ deficiencies were resolved, I supplemented only 3 times a week. And I will often go for 4-6 weeks at a time with almost no supplements. I tune into what their bodies are saying to me, or whether they’re asking for supplementation.

However, I always have free-choice Redmond and Himalayan salt (loose and in rocks to lick) available. Interestingly, they usually prefer the Himalayan pink salt.

When the latest batch of wild mustangs arrived (Kaliah and her herd) I also put out a free-choice bucket of Hoffman’s Minerals. Even though it is has too much iron (since our grass/hay is already high in iron) and contained some wheat, I felt it was best to let the horses decide what deficiencies were most important. Well they hoovered those minerals for 3 weeks straight – they ate more in 3 weeks than my resident herd had eaten in 2 years. So they must have had a serious mineral deficiency. After that first 3 weeks was over, however, they’ve barely touched them. In fact, I have not topped up the bucket in over 8 months now, it just sits there.

Iron can cause Laminitis and Cushing’s

The really key thing to watch out for with equine supplementation, is to make sure your horse is not getting too much iron. Iron has to be in the correct ratio with zinc and copper, or it contributes to laminitis, insulin resistance and equine Cushing’s disease.

Most equine supplement blends have iron in them, and if you feed a mineral blend (like Hoffman’s Minerals) it can have a high iron level in it. Now, the iron is probably balanced in the correct ratios with zinc and copper within each product. BUT you need to also get your hay tested and if the iron content is high in your hay (which it often/usually is) then you’ll need to also add extra zinc and copper to your supplement regimen to balance out the iron in your supplement.

According to Dr. Getty in Feed Your Horse Like A Horse, the zinc level should be similar to the iron level (but iron should be not more than 5x the zinc level), and zinc should be 3-5 times higher than copper, to establish the correct absorption ratio.

When I got our hay tested, sure enough, as Dr. Getty suggested, the iron level in our hay was 9x higher than zinc, and so completely out of balance with the zinc and copper. So that’s why I only use HorseTech’s High Point Grass vitamin/mineral supplement – which is formulated specifically for horses primarily fed grass and/or hay.

You can also have HorseTech look at your hay analysis and create a custom-blended supplement specifically for your horse, if you wish.

Summary

If you’re NOT going to get your hay tested to determine the iron level, then it’s probably best to feed HorseTech’s High Point Grass supplement, to be on the safe side. Add extra magnesium, flax oil (or ground flax, or ground chia), seaweed, and salt if required. And make sure you are feeding a complementary amino acid profile (alfalfa, flax seed, etc) to make up for the amino acids missing in hay or grass.

If you are in the UK, this is the best local supplement I found – excellent quality ingredients, they do not add any iron, and the zinc and copper are in the correct ratio: Thunderbrook Equestrian Base Mix. Although HorseTech does have customers from the UK who order from them, even though the shipping costs almost as much as the product.

    Hi Jini,

    Thanks for the great post — I’d be curious to get your take on this feed, which I feed to my horse who is healthy but has been diagnosed with ERU (he also gets an herbal tincture daily and 2 scoops of aniprin). We do a hay/grass diet and then I use a bit of this feed to get supplements and the aniprin in, along with sunflower and pumpkin seeds.

    CoolStance Copra – http://www.stanceequine.com/product-coolstance-copra Looked good but I’m considering switching to the High Point based on your article, but would like to see what you think of this one from a nutritional perspective.

    Thanks!

      Hi Elyse, most of the ‘ideal ranges’ for the vitamins/minerals researched for this article come from the work of equine nutritionist, Dr. Juliet Getty. Combined with referencing the Merck Vet Manual and a few other University equine research sources. So – as Dr. Getty sells the High Point feed on her website, and at a discount over buying straight from the manufacturer – I would contact her with your question and get her to assess the CoolStance product for you.

      You could ask her something like this, “I’m thinking of buying the High Point feed, but I’m not sure as my horse is currently on CoolStance and doing well. Could you please tell me why I should buy High Point rather than CoolStance?”

      The other thing you could do is compare the ingredient list of the two products and then just double-check the zinc/copper/iron ratio as outlined in this post.

      Please let us know what you find out…

        Dr. Teskey in his “decomplexicating eq nutrition” blogs/ course recommends “Cool Stance”,, it is dried dessicated coconut, nothing else . I looked into buying it at Country Feeds in Langley, it was selling for about $75.00 /44 lb bag., last checked for it in Sept /18. I don’t know the nutrient components tho.

    VACCINATION?

    I just received this question from a reader, so thought I would post our exchange here in case anyone else is wondering…

    QUESTION: “Hi there….I first have to thank you for your valuable, informative website. I have 2 rescues; one an elderly blind POA with PPID, and the other an Arab/Andalusian whom I have been playing at liberty with for a year. I haven’t had horses in my life for 30 years. The learning curve is steep, but oh so rewarding.

    Our vet is coming in a few weeks. She wants to vaccinate for West Nile. I definitely will NOT do the blind PPID pony, but I wonder what you would do? I don’t do Big Pharma myself, but I see the value in a tetanus shot, but seriously question the need for West Nile. I searched your blog before writing to you, but didn’t see this aspect of horse care addressed. Thanks so much for all that you offer.”

    ANSWER: You’re very welcome and so glad you are enjoying the blog 🙂

    I have researched vaccination thoroughly – my article (for humans) was published in magazines in the US and Australia and is also on the National Vaccine Advisory Council website AND I do not vaccinate any of my animals or children.

    Recently, my dogs required a rabies vaccine to cross the border – and my holistic vet gave them a homeopathic vaccine and filled out the forms as if she’d given them the drug one. Yay!

    There is a very good book, “Holistic Horsekeeping” by Madalyn Ward DVM which has lots of great info on why she doesn’t like to vaccinate horses and what you can do instead. She talks directly about West Nile too. She says:

    “When a patient of mine contracted West Nile (verified through titers), we were able to stop the progression of symptoms within 12 hours and restore the horse to normal health within 48 hours using several homeopathic remedies.”

    Hope that helps, and what a wonderful adventure you’re on! Perhaps I’ll do a longer post specifically on vaccination in the future.

    I was reading your comments on Hoffmans feed. I have been feeding there Hay saver as a Hay saver. It’s quite unfortunate that this company won’t list the Sugar content in this product ” on the bag ” ! They seem to have listed everything else but failed in mentioning it contains over 20% sugar. This high of sugar is not recommended for horses that have metabolic problem or for ones that have a founder problem.
    Where I purchased it they sold it as No sugar product. I wanted to let people know to be careful when feeding all these types of grains and hay products. Never assume only what the label says. Contact the company directly if you can as this can really set the problematic horses that are trying to get treatment way back. I’m quite dissapointed with the product and wouldn’t personally use it after the lack of information on the packaging.
    Just thought I’d share, as I feel it’s important to some people to know this.

    I re-read this article to see what I am missing since I realized in looking at older photos and paying attention to details, that my horses’ hooves are really dry, and the 3 of them who have been with me for more than one year (not Rayo, since it’s not even been one year since I’ve had him and can’t compare) had longer/ticker manes…. they have now been off pasture due to our move on our pasture-less land since last Nov…..It seems the lack of grass for almost a year has really affected them. 🙁 They have been on supplements since March/April and get a host of stuff, maybe not enough.

    I just wonder how much I can add to their diet if there is no grass available to them. Does anybody have their horses off grass 24/7? What is their diet besides hay?

    My horses get hay 24/7 in nets and loose, and the hay varies thru the year. I try to buy from at least 3 different sources so the hay varies (different cuttings too). The supplements include flax, vit E, A, magnesium, and a supplemental multi vitamin/mineral.

    Jini, you still give the horses all the oils? I wonder about oils since they would not get oils in the wild….but maybe I need to add oils and more flax (I do grind the flax just before serving). Anybody? Thanks!

      Yes, I still give them ground flax and/or flax oil – about 3x/week. Dr. Getty just covered this very topic in her newsletter! She prefers chia to flax and the dosage for chia she recommends is:

      “An 1100 lb (500 kg) horse does well with ¼ cup (2 fluid ounces) to ½ cup (4 fluid ounces) of chia seeds per day, which weighs approximately 2 to 4 ounces (approximately 50 to 100 grams), respectively. For serious health issues, dosing can be increased up to 1 cup (8 fluid ounces or 200 grams) per day, divided between meals. It is best to add water to them and allow them to plump up a bit before being fed, however, they do not need to be soaked and may be fed dry. ”
