Walk, we actually have Evented for the past 3 years, and this year switched to mostly Hunter/Jumper but still like to do some Jumper-type competitions and Hunter Paces here and there. She is ridden probably anywhere from 3-5 times per week, for about an hour each time, jumped probably once once, maybe twice per week. When I only had her on grass pasture/hay and the barley alone, she started losing weight.
I tried a fat supplement (Cool Calories) which didn't do anything, and then SmartPak recommended the Tri Amino and that's what put the weight back on her. She's also on Augment, a multi vitamin, since the barley doesn't give her much of anything besides something to mix her supplements in.
But it would be nice to have her on a grain of some type that's got everything she needs in it, and that way I could drop the 2 supplements I have her on. But if I can't find a grain that would work, I'll probably just continue with the barley and supplements I have her on, since those have seemed to work alright.
