I've bought an OTTB, 5 yo 15.3hh and I'm struggling to get weight on him. I've bought whole lupins to add. Silly question but do I remove the hulls once I've soaked them? His daily feed atm: 1 biscuit high quality Lucerne 1 biscuit oaten hay 2 large scoops Lucerne chaff 2 large scoops oaten chaff 1 large scoop hygain tru gain 24/7 pasture Bran mash once a week. Does this look ok? I tried speedibeet but it made him colicky. So I'm going to add lupins, is half a cup (before being soaked) too much to start with? FYI. He's been wormed twice so far with me. Teeth done. Next step is checking for ulcers- but his appetite is huge and he stopped racing last march (only 5 starts).
