How about flax? It helped my boy get over the top on the weight scale.
Also, I am not one that jumps on the ulcer bandwagon but TB + Cribbing makes me think there might be a digestion problem there. Treating for ulcers with either an ulcerguard type product or even some of the natural solutions couldn't hurt.
Add to that, my TB is content to stay slim. He has a crappy appetite unless he is in actual work. A few minutes lunging might up his appetite for not only his pellets but even for his grazing.
Where could I find it? If I could find it raw say, at Walmart, that would be great, versus having to special order it in a supplement.....
I'm going to get the scoping done because he was on the track for quite awhile; 95 starts under his belt, and they say that something like 80% have ulcers. Plus, when you get the scoping done, if you they do have ulcers, the vet will give you two tubes of Ulcerguard free, a discount on the rest. His poop is solid though, so there's really no indication of digestive upset accept his lack of fat in his ribs. He's never colicked in the three years I've had him, either.
Oh, he is not a picky eater. He's a pig. He will eat anything, all of the time. even though he's on grass all day, if we're walking through tall grass and we stop, his head is immediately down. I am not
worried about him turning food away, haha!
Right now, since he's thin and its so hot, I'm wary of putting him in work. But I am looking for someone to ride him regularly, because I can only make it to the barns on weekends, and that is just not enough saddle time to keep him from behaving like a pill when I do get to ride. In my previous experience with him, he is so much better when being ridden 4 times a week than two but I can't do that with my current job. I know that when I was riding him 4 times a week, his topline
looked better, but his ribs were unaffected, but I don't have during and after pictures to really be able to tell. So while I am looking for a rider, I am hesitant about it and if I see him get thinner once that happens, he won't be ridden.
