I'd rather it be muscle, but at the moment I'll settle for fat because he's outdoor kept and it's starting to get cold out and I want to avoid blanketing if I can help it - the other horses will just tear off any blankets anyways :(
He's on about two cups of grain a day at the moment - I used to use Trimax but switched to ruffage cubes for the winter as I can't ride as much now. And he has access to hay 24/7.
This is him in August, he's gotten fluffier since then, but I'd like to see a little more over his ribs.
Any tips or tricks out there?
