3 out of my 4 horses do well on it, but my big lad just came out in weird itchy spots, loads of them, all over his back/quarters. They cleared up when I put him on hi fi nuts instead. A friend said it made her boy footy, but my laminitic does well on it.
Thanks all, it's def worth knowing all of this. I also found a lot out about soya by asking hho'ers to share experiences, shaln't be using that stuff anymore!
