My question is what is this article touting as the best thing to feed? 'Cause you know there has to be an angle, and whoever wrote it is out to make money off the people who would believe this pseudo-science garble.
I feed beet pulp in the winter. My horses don't need it in the summer, as they're not burning extra calories trying to stay warm. I feed soaked shreds, added in with their regular rations. I also don't soak it for hours upon hours. Ten minutes tops, and it's ready for the horses to eat.
ALL senior feeds have beet pulp in them. If it was so horrible and made horses lose weight, I doubt it would be in there. Besides, it's not like the sugar beet industry has
to sell the pulp specifically to the horse feed manufacturers or it'll go to waste. It can be fed to a variety of livestock.
