My horse doesn't really like anything soaked, and he will NOT touch beet pulp, no matter what else is in it. He's also very suspicious of any type of powdered supplement. He was on Ultium for a long time, which he thought was OK, but he would only eat a certain amount of it and then walk away. He was working really hard last summer, and I couldn't keep the weight on him. I switched him to Fibregized Omega, and he hoovers up at every feeding. He likes it so much, I was even able to add a powdered weight gain supplement (KPP EndurExtra), and he's looking great now.
Fibregized has a tendency to clump, especially the Omega version, and especially in the winter. I add a half a cup of water to break up the clumps so he doesn't choke.
