So I went and looked up, what's high in zinc? Copper? Magnesium? Found some interesting info! So I'm thinking of making some daily-horse-cookies with some combination of oat bran (very high in magnesium), toasted wheat germ or peanut butter (zinc), and sesami seeds (high in copper). Besides that, the usual shredded carrots (vitamins A E,K), salt, possibly other things, orange juice mixed in there?
So I wanted to know, does anyone here do anything similar? I'd love to hear some home made supplement recipes, if there are any floating around. Also, is there anything terrible for horses I might not know about, and foods to keep away from? Thanks horse people.
