The importance of overgrazing is that you shouldn't do it! Horses and other farm animals are supposed to eat constantly, but if a horse is left in a field of lush green grass for too long then, you may kill it. Horses can get collic from eating too much, and they can get founder from gaining too much weight. So whatever you do, make sure you don't overgraze you livestock or pets!
