Re: Cluster of Severe EMS Cases


I have three purebred Arabian mares who are PPID/IR. I will start with the oldest:
1. We are in Duncan on southern Vancouver Island, British Columbia, Canada. We cleared the property and put it in pasture using it as a horse farm since 1972. (I think that is 48 years!)
2. The first mare is now 20 years old she is a purebred Arabian born in Santa Maria, Calif, and coming here as a 4 yr old. She has been here 16 years.
3. Do not have insulin & Glucose numbers until 2018 but she was clinically PPID at age 15 and has been on Prascend for 5 years, moving up from 1mg to 3mg over time, and currently on 3.5 compounded pergolide. In Sept 2018 her insulin was 1787 pmol/L ('normal' range 28 -390) glucose 6.5 mmol/L (range 3.6-5.7) and ACTH was 8.1  pmol/L range 4.62-11.66. She was not worsening at this stage but those are numbers she had at the start of a study for producing a product that would hopefully lower insulin/glucose numbers.
4. We currently feed our own-grown grass mix hay. It is analyzed at under 10% s/s (usually around 8%)and previously we brought grass hay in from B.C. interior and Washington state with low s/s (at great cost here on the Island) with even lower numbers to supplement our crop and in years where we did not grow hay. she is fed at 2% bodyweight, all hay is weighed.
5. None of our horses have ever been fed grain. They get minimal beet pulp, timothy/alfalfa cubes, alfalfa pellets, soy hulls moistened to  hold their salt, flax, mag.ox and vitamins/minerals. She also gets 30 min to a couple of hours daily of pasture depending on time of year. Barefoot all her life.
6. Treatment for this mare has been exercise, diet and pergolide. We did try Quiessence with no noticeable effect. She is 15.2+ and basically a constant weight around 1000 lb. although looking ribby for the last several yeas. She has also had laminitic episodes (May 2016 & Apr 2019) and required bute, boots. We also do winter trace clipping to combat sweating. She has always been a big salt eater, a heavy drinker and consequently heavy urinator (we had thought it was her California upbringing). What has made a dramatic turnaround for this horse and our other two mares is WIRX. This is the product developed here on the Island. It is all natural and it dropped this mare's insulin to within 'normal' limits. One year later (Sept 2019) her insulin was 233 (down from 1787, although her glucose was 5.8 just a squeak above range. These readings were taken always 3 hours after first feed of the day. This mare and the others have lost or reduced the fat pads typical of the IR horse over the year as well and their whole demeanor has improved. The only change in this mare's life was the WIRX product. 
I'll do my next girl on a separate e-mail.
