Interesting article by Joanne Meszoly in July 17 mag., stating three components:
Obesity, Insulin Resitance and Laminitis.
To me, much focus was on overweight horses. Perhaps I am misunderstanding IR - thinking I have read that not all IR are overweight. Are all "only" IR horses overweight with cresty necks and fat pads, etc?
No. Dr. Nick Frank, one of the leading researchers of EMS, reported at the Eq Sci Soc meeting May 2009 that the thin horses with hyperinsulinemia are far more difficult to manage. Many horses with very high insulin have all ribs showing, and still have abnormal fat deposits. Mine are in that category. We have to stop obsessing on ribs. I asked Dr. Henneke at the ESS meeting, and he told me that his body condition scoring is based on normal horses and does NOT work on horses with EMS.
Has anyone else read the article to which I refer? Perhaps I misunderstood some things.
Otherwise perhaps a kind rebuttal might be in order to caution folks that they are not "safe" just because their horses are not fat.
"Insulin-resistant horses that are thin or being worked
may require additional calories, but care must be taken
to provide energy without exacerbating insulin resistance.
Affected horses may be leaner but still have a
cresty neck and enlarged fat pads."
