I was able to get a look at the NSCs reported by Blue Seal for their various feeds when I was trying to figure out how to feed my IR mare. I cannot remember the exact numbers, but the Sentinel LS isn't low enough to be safe for and IR horse. This was the feed my IR mare was getting when she became extremely obese.

If you get in touch with Blue Seal, they should be able to tell you what the NSC of the feed is. And a feed store that carries Blue Seal feeds should have a fact sheet that will list the NSCs of all their feeds.

Hello Erin,

Since both feeds contain cereal grains, the NSC is going to be too high in both feeds. The Blue Seal is mostly corn, so I expect its NSC level is around 50% or higher. The Sentinel LS is much lower, probably around 25% (in my experience with these formulations) but that, too, is too high for an IR horse.

You're looking for a feed that has less than 12% NSC, which is why I recommend TC Low Starch. Purina Wellsolve LS is also worthwhile. And I believe LMF makes one that is low enough, as well.

All the best,
