Can we start a COTH list of horse feeds that are NOT milled with cattle/livestock feed?

That’s why I wish someone had and would post a picture of the ingredients in the Soothing Pink, so we can narrow down what’s probably a small list of differences between it and the Extra Strength formula, to try to figure out what ingredient it was.

I find it interesting that an Extra Strength product does have at least 1 of the ingredients that’s in the regular formula, but that may be because they replaced it with either something else that does the same thing but better, or with a couple other ingredients that when used together provide more benefit.

Clearly this has some relation to an ingredient used for ulcer prevention. I’d doubt it would be any of the normal herbal ingredients, like aloe, or slippery elm, as I wouldn’t think those things would be sourced from agricultural sources but I guess anything’s possible lol

Thanks! Someone found an archived page for the pelleted version

And they are slightly different ingredient lists.

And now I’m not sure if the problem product was the powder or the pellets. Did I miss where that was clarified?

So, new question:

I’ve been looking but can’t find if there’s any info on what, if any, ingredients feed/supplement companies are required to test for.

Are they even required to test for rumensin if they’re making an equine product? Or do they because they know what happens if they don’t?

Are they required to test for salmonella,or mycotoxins? Or do they simply because of the damage to their company if they don’t.

I can only imagine they are not remotely required to test for any ingredients there are merely banned, ie ractopamine.
