When feeding any animal, the most important thing is to feed the correct amount of calories in order to keep the animal at a healthy weight. Animals that are too heavy develop health problems, and so do animals that are too thin. Very few individuals have a scale big enough to walk a horse onto, so most horse owners resort to other methods to estimate the horse's weight. A tape passed around the girth can be used to estimate a horse's weight. Tapes marked with estimated horse's weight are sold at most tack stores.
