The belly is most likely (and I say this with almost up most certainty as I can without seeing the horse myself) the reason for the swelling belly is a grass belly, meaning they're eating too much grass, much like a beer belly men who drink a lot get.
Grazing muzzles work wonderfully, and are the most humane way to get them to cut back on eating. They can be left on the whole time they're on pasture, and whomever feeds the horse can easily remove and put back on the muzzle around feeding times. It's important to exercise them a lot just like people, exercise AND diet are key to losing the weight.
I am still under the impression that there is nothing alive quite so beautiful as a thoroughbred horse.
