My friend uses this and her horses love it and look fabulous on it, I think it is cherry flavoured. I wish mine weren't fatties as I would love to feed it myself.
I give it to my horse (who is fat ) coz they didn't have his diet chaff in stock the day I went feed shopping and this one, whilst high oil, is low sugar and I figured it was the lesser of two evils. He literally gets a fistful a day to carry a supplement and his coat gleams. Highly recommend it!
