When a horse is underweight it coud be from many reasons, stress, not proper feeding, poor pasture, worms ect. A really easy way to put weight on a horse is to ad karo syrup to their feed you would be amazed how well it puts weight on them. Put enough in their to lightly cover the feed. Also make sure you feed ALOT of hay because that is what horses pretty much get there protien and weight from make sure it is a good quality hay also not just a filler
