I have read a bit on Diatomaceous earth and the rescue I work at swears by it (but doesn't always do things by the book or how they're supposed to be done). So my questions are, do you or anyone you know use it? Is it effective for your horses? How much do you give your horses and how often?
I would of course run this by my vet before doing anything, but I want to know whether it's worth the consultation phone call honestly :P
