I read from one article that boiled grains are good foods for horses. Horses would regain their weight faster when eating boiled grains. But there are only a handful of grains that can be eaten by horses and examples are barley and oats.

Would anyone support this idea or actually feed their horses with boiled grains? We haven't tried this one but might actually give this kind of diet to our horses if someone could support this idea.

I've never fed boiled grains as a primary diet for horses. I've fed bran mash which is a boiled bran mixture, normally with some molasses and boiled beet pulp, but only as a supplementary diet in winter or as a treat. I would imagine the grain when whole and boiled would add weight faster than a pelleted grain which uses parts of different grains. Putting weight on a horse can be a tricky thing and is normally best done with the advice and guidance of a vet. They can better evaluate why the horse is underweight as it can be from underfeeding, overworking, worms or other issues such as age. Alot of older horses get to a point where they always look thin, no matter how well they are fed or what you try.

This might sound odd, but wouldn't that be the same thing as when a person eats oatmeal, since it kind of "sticks" to their stomach, making them stay fuller longer and gain the weight quicker?

This is also the reason why I will not try feeding them unless someone would really tell me what are the results of feeding boiled whole grains. Our horses are healthy at the moment and I would like to try this kind of food if they like it or not.
