Legit answer is they have chambered stomachs like all grazing herbivores, which allows them to digest grains better and get more protein

Pic related is a natty horse.
I took this just this morning.
Horses owned by people usually aren't natty.
These wild horses are still powerful, and these specific ones have an advantage over REAL wild horses because these ones roam on a military base where there's planty of water sources and people throwing food to them

This, plus you go yo remember horses can weigh anywhere from 900 - 2000lbs. That's a lot of weight to carry around.
