IR means the horse is insulin resistant -- same as a human that is Type II diabetic.
While the stereo-typical IR/EMS (equine metabolic syndrome) and Cushings horses are easy keepers, thin horses can also develop these diseases.
To the OP:
If you can get stabilized, calcium fortified, pelleted rice bran in your area, that is what I feed my I-R horse at the recommendation of an equine nutritionist when the IR exploded on him two years ago.
I have yet to hear of a horse choke on pelleted rice bran.
Plus there's no time wasted having to soak the molasses out if you can't find molasses free beet pulp, not to mention all the time involved in the soaking process.
I put all my horses on rice bran and they are much better for it. It was how I accidentally discovered one horse's snarky disposition was driven by an intolerance to oats & corn. For 12-1/2 years I've called him A.D.D. And here he's had a food intolerance so slight that I chalked his attitude up to
His blood line
I feed a pelleted vit/min supplement and Omega-3 horseshine
With the pelleted rice bran. That way I can increase or decrease the rice bran without interferring in their vitamin/mineral intake.
Everyone's on 12 hour turnout on good pasture. For now they all get 1-1/4 household measuring cup divided into two feedings.
Once winter sets in and the pasture goes down, I will increase that to two measuring cups divided into two feedings.
Rice bran is 20% healthy fat, so it doesn't take much
If you look at the horses in the "featured testimonial", those would be my Boys.
The second one from the left is my 22 yo that is insulin resistant. He is the same horse in my avatar except he was 16 and the I-R hadn't taken control yet He was still his high powered go-go-go self, but not having any knowledge of IR back than, I was oblivious to the early symptoms.
So no, nldiaz66;352108, your question is far from dumb
