This depends honestly.Some horses will eat all of the food put in front of them until they become ill and require veterinarian attention, whereas other horses will almost starve themselves. Luckily most horse fall in the middle of these two extremes.Horses (average light horse breeds) require 1.5 to 3% of their bodyweight daily. If you put out 1.5% to start and the horse eats everything but seems thin, then move up to 2% and repeat the process. Some horses may reach the full 3% but still seem thin, you'll need to add fat to the diet in some form or the other.
I guess they would eat their normal every-day food
All horses are different, and that means they eat different amts. of food. Some horses will eat until they get sick, and some may not eat enough. Therefore, there is no specific amt. for horses to eat.
horses can eat up to 20 pounds of food a day so in a year they could eat 7,300 pounds of food. It depends on your horse's diet and the size.
horses can graze (eat) for up to 16 hours a day.
Sea horses eat their food through their snout. Sea horses eat continuously as they do not have completely functional digestive systems.
all horses can eat hay/grass. all horses can eat hay/grass.
A wild horse, just like domestic horses, eat around 3% to 5% of their body weight per day.
Most horses eat almost all day if their in a pasture with grass but if they have foundered, old age, or sick they might not eat as much as usual if any at all.
Horses eat grass, they graze.
they chew on food
