Obviously that person that wrote the answer before me never owned a horse.A horse's diet should consist mainly of hay/grass and grain or feed of some sort. Sugar cubes should NOT be fed to horses. People think it's okay, but it's really not. Horses shouldn't have any people food like gingersnaps or whatever. My friends give their horses people food all the time, but it's really not good for the horse.Some tree leaves are poisonous to horses like oak, maple and yew tree leaves. There are plants poisonous to horses, but usually horses don't eat these plants anyway. For example, buttercups are poisonous to horses, and though they exist in almost every horse's field, horses don't eat them.There's a lot of things horses shouldn't eat. I think the question should've been what can horses eat. haha.
they had no horses and needed it for food ect.
Normal food... But with poisonous chemicals in it.
Horses should be left to eat horse food, not people food, just to be safe.
Short answer: yes. Many people survive food poisoning.
Leylandii is not poisonous to goats if they eat it. Goats are not known to eat this kind of tree but will if it is the only source of food available.
the horses food is brought to them. . .
Pine trees are not good for horses to eat. They may try to eat any tree if food is not present and they have not eaten in awhile. Some horses chew on trees because they are bored.
If a horse is owned by people they get there food from people, at least if you have a horse I hope that's what you do. Anyway, if a horse is wild thy have to find food for themselves.
Disease, poisonous animals, unclean water, lack of food. It depends on what part of Africa though.
