All points of eating are good ones. But we all know the horse that is in racing condition is underfed to keep him fit and light on his feet. Horses will overeat if given the opportunity. If you think that race horses are treated like kings, try living the life of a horse for 1 year. Move into a room that is 10x10 and spend 20 hours a day there, be fed when someone tells you to be fed, be whipped when being trained and then come back to me and tell me how you like it. Sure most horses have a better chance in captivity but sometimes nature has to take its course.
