Horses should have access to a mineral block in the pasture, brown like a salt block, or add one tablespoon of loose minerals to its grain meal twice a day.
A salt lick is good.

Sometimes foals will start eating their own or their mother's dung in an attempt to get the nutrients that they are lacking. Eating dung is not dangerous for the horse, but doing so is a sign that the horse may be malnourished. A vet should be consulted on the proper diet and supplements for the horse and what his proper weight should be.

A good grazing area and a salt block! :)
If a horse is lacking minerals in it's diet you can add a mineral supplement either in a block form or in a loose form. If the mineral supplement does not seem to work you can also add a pelleted ration balancer or mineral enhanced feed. It is always recommended to consult with a equine veterinarian regarding any dietary changes.
You add a salt lick to its diet.
it has diomands and minnerals so it could be black white glossy or grey
You buy minerals and add it to the feed, or you get a red(mineral) salt lick that is always accesible to a horse.
Give it a salt block... Let it graze... Or get a vet reccomended supplment. :)
