By spring, I could actually see a faint outline of ribs and his hips started to jut out a bit. As the weather warmed up, I was confident he would start packing on some pounds. He didn't. So by the beginning of May, I started to really worry that he might have a metabolic condition that was preventing him from gaining weight.
Through our discussion, she pointed out that Speedy might simply be burning off more calories in his night turn out than we realized. At our last barn, where he lived for five years, Speedy had a large stall/paddock that was about 24 by 36 feet, generous by most standards. He had a small track worn into the ground where he paced and circled, but it wasn't big enough to walk miles. His current turnout is.
A week later, I am already seeing the tiniest bit of padding starting to develop. He's getting a good eight pounds of supplemental feed daily in addition to all the alfalfa he can consume. I am giving him until the end of June to put on a bit more weight. If I don't see it, he's definitely getting some blood work done.
I wish I could simply walk off my excess pounds!
