Equine Hair Analysis by Karen Eddings: Hershey’s Results

Last year, as I was doing research for a post on TMJ, I came across an article written by a lady named Karen Eddings, aka the ‘Equine Nurse’.  I later looked through Karen’s website and asked if she would be interested in doing in interview for the blog.   (You can read her interview here.) Karen specializes in animal and human biofeedback and hair analysis, among other things.

I was curious about doing the equine hair analysis–as Karen does it differently than most labs or vets do.  Instead of analyzing the hair for specific mineral levels, Karen uses a biofeedback machine to assess the hair follicle.  The result is a computerized list of imbalances within the horse (unless, of course, the horse is perfectly healthy!).

So late last summer, I decided to give the hair analysis a try with Hershey.  As you long-time followers probably know, Hershey is the reason I became interested in acupressure, barefoot trimming, and natural horse health in the first place.  The issues he’s had for a number of years now have kept me questioning many things and have also inspired me to continue to learn as much as I can about horse health.

Last summer, I had two main concerns with him though.  One, he had recently lost some weight, and two, his hooves continued to be plagued by problems– despite being supplemented  with custom minerals balanced according to my hay/ pasture analyses and receiving a natural trim every 3-4 weeks.



Here are the vertical cracks Hershey’s had for many years now.


I thought by doing the hair analysis, I just might learn something that I hadn’t thought of yet  — although I couldn’t possibly imagine what that might be!

I followed the directions on Karen’s website and mailed in the hair sample from Hershey’s tail.  She e-mailed me about a week later with the results.  This was also followed by a phone consultation a few days later.

Even though I was expecting some sort of issues to show up from the hair analysis, I was not expecting the list that I received.  According to the analysis, Hershey had a number of imbalances, including in many minerals.  He also had several disorders according to the biofeedback machine–three of which were ligament disorder, hormone disorder, and malabsorption syndrome.

The ligament disorder immediately made sense to me because in Traditional Chinese Medicine, the hooves are viewed an extension of the ligaments.  So an imbalance within the ligaments could easily show up in the hooves.

The malabsorption syndrome was something that I’d heard of before (it’s common with older horses), but hadn’t considered as a possibility with Hershey.   However, I began to see how this could, indeed, be one of Hershey’s major issues.   Despite 24/7 access to pasture or hay, he’s always been a ‘hard keeper’.  At age 22 now, I suppose it shouldn’t be a surprise that the problem has gotten worse.  I also thought about his feet again and why the cracks and poor hoof wall quality had remained after everything I’d done.  If he wasn’t absorbing the custom supplements I was feeding, then of course his feet weren’t going to improve!

(by the way, when Pete Ramey trimmed Hershey at my workshop in January, he even wondered if Hershey weren’t absorbing the minerals I was feeding. . .)

The hair analysis results also showed a ‘perverse energy overload’–in particular from power tools and cell phone radiation.  I found this interesting because my husband’s workshop is right next to the pasture.  There is also a cell phone tower not far from our house.  Of course, there’s not much I can do about these things though. . .

I did, however, want to focus on the things that I could possibly help with– the mineral imbalances and  malabsorption syndrome.  Karen suggested I first put Hershey on a zeolite/ silica supplement (Enviromin) for a gentle detox and then switch to free-choice mineral–specifically a brand called Big Sky–so that he could balance himself out.

I have to say that this was my biggest hang-up with all the results and advice she gave me.  After all, I’d spent years learning about and preaching hay/pasture analyses and customizing minerals according to specific deficiencies in the forage.  I was very leery about trying free choice minerals.

I did the detox supplement right away and reluctantly agreed to try the free-choice minerals. But after doing some research, I decided to go with a different (and fairly pricey) mineral because it had no added iron (ABC’s Rush Creek Mineral).  My horses loved this mineral and I might have had good results with it, but I simply could not afford to keep feeding it.  My four horses went through three 25 pound bags in about three weeks.

So after that, I went back to top-dressing minerals as I had previously done.  But I still wasn’t getting anywhere with Hershey. . .

So finally, about two months ago, I  said this to myself–you know, Casie–you’ve tried everything else under the sun and nothing has really worked.  Why not take Karen’s advice and try the Big Sky Minerals?  Could it really hurt?

So I decided to bite the bullet and order my first bag.

My horses have now been on Big Sky Minerals for about a month and a half and believe it or not, I am actually seeing some positive changes in Hershey’s feet for the first time!    The mild but chronic thrush we’d constantly been battling has seemingly disappeared.  (Lee Lee also suffered from mild thrush and it has cleared up as well.)



If you look closely, you can see the deep crevice in the back of Hershey’s frog here. This is a telltale sign of thrush.  Happens all the time, even with very dry hooves.


Here you can see that even with the extremely wet weather we've been having this spring, the crack is gone--no thrush!

Here you can see that even with the extremely wet weather we’ve been having this spring, the crack is gone–no thrush!


Hershey still has the vertical cracks in his feet, but I am daring to hope that the free choice minerals will help with those too.  Only time will tell, I guess.

Hershey is also finally putting some weight back on and I’m very happy about that.

I promised Karen I would do this review when she did the hair analysis for me.  I just wished I’d taken her advice sooner.  The biofeedback analysis was definitely worth it and I’m also becoming a big fan of free choice minerals and Big Sky.  As always though, I will keep you updated!

My favorite piece of advice from Karen was this though:  Keep it simple.  That’s what I’m now learning to do.  Who knows, maybe my horses don’t need a micro-manager after all. . . 🙂

    Believe it or not, I give my horses 2:1 beef mineral from Southern States free choice. The horses love it (formerly wild mustangs) and so do my donkeys. It is not expensive either.

      Glad that’s working for you, Victoria. I don’t usually endorse or recommend one particular brand or product because what works for one horse may not work for another. With that said, I am quite intrigued by the free choice mineral concept now though!

    Fantastic article!! Thank you so much!!!

    Hello Casie,

    I looked up Big Sky and can’t find the specific ingredients and mineral percentages. Do you have any more information on this?

    I just wanted to comment about the minerals. Hooves need copper and zinc to grow and be healthy. Excess iron cancels the absorption of copper and zinc- even if there is an “adequate” amount of those minerals available. This is from Pete Ramey’s page at http://www.hoofrehab.com/Diet.html

    I would guess that the iron in your favorite supplement was responsible for Hershey’s malabsorbtion and mineral imbalance.

    • Casie says:

      Hi Rosalie–I am well aware of iron and how it affects on the absorption of other minerals. I took Dr. Kellon’s courses and have even written on iron overload before. I went out of my way to avoid iron and only supplement individual minerals (from Horsetech) that were lacking in my forage analyses (copper, zinc, magnesium, usually). I even fed CA Trace which has no added iron. Iron was not the issue with Hershey. Iron was, however, one of the main reasons why I was very hesitant to use Big Sky minerals-as it is included as an ingredient. However, I went with what my gut was telling me–to just give it a try. Now that my horses have been on it for nearly 2 months, they look better than they have in years… I can’t tell you why exactly that is–because free choice mineral feeding (with added iron) goes against everything I learned in my nutrition courses–but it’s the truth.
