Horses, cows, pigs, chickens, rabbits, turtles, birds, and many others.

However, horses, cows, pigs and rabbits only eat grain when they are fed to them by humans... usually to fatten them up. Normally they would eat leaves from pastures and other vegetables. There are no mammals who eat a significant amount of grain as part of their natural diet. That includes humans up until the last 10k years (advent of agriculture) and that quantity was still much, much lower than it was after the industrial revolution. It then grew progressively worse as low fat diets that suggested more grain were promoted by US and other governments... right in line with "the obesity crisis" and type II Diabetes.

In other words... "it's for the birds"
