grass-hay -grains-veggies(carrots)-fruit-(apples)--sugar cubes. Go to a feed mill They can advise you on horses diet.

They are herbivores, but not ruminants (they only have one stomach, no rumen).  And they do best with a grazers diet, meaning they are designed to have little bits over a long time of their day.  Think of them in the wild, they eat, walk, eat, walk, run from predator, stop, eat, walk.  They therefore almost never get colic in nature.  We put them in stalls, bulk up grain rations, give some forages that they wolf down, twice per day, hold them in confined paddocks, and they do not eat and walk, like their gut is designed, we get more colics!
