I definitely don’t disagree that the group is immensely valuable. I was just pointing out that blanket statements of “no bagged feed is good for any IR horse” isn’t valid, and that just because they recommend not using one doesn’t make them invalid either. Ditching them, going back to as basic a diet as you can (low sugar hay + important supplements, for example) and letting things settle, is never a bad idea. That’s where some horses have to stay, but it’s not where all have to stay.
It is definitely possible, maybe often healthier, to feed a-la-carte. But it’s not always economical for the harder keeper, and having to use too many different things in a boarding situation is often not a viable option. Fortunately, there are some really good, very low NSC bagged feeds out there for some luckier folks to choose from.
