She was talking to a horseman last year who said that he feeds bread to his hard keepers (in addition to regular feed) in the winter. He goes to bakeries/supermarkets and gets the 'old' bread cheap or free. So the horse gets ? Maybe 1 to 5 loaves a day?
Has anyone ever heard of or done this? Results, pros/ cons? Is it ok to do this?
Let's assume that the bread may be stale, but Not mouldy.
