I think Strategy is a good, all-around feed. I would think if there was undigested food going through them, they wouldn't be getting much nutrition from it but I don't know.
Well it looks to me the horses I've seen who are fed whole grains ALWAYS have some grain in their poop. I like pellets. Rather they're chewed up or not, they still break down.
The proof is in the pudding tho. Your horses all look great, so alfalfa must be fine, and IMO, my horses lood pretty good:), so complete pellets must be fine. More then one way to skin a cat, or feed a horse:)
