After a bit of reading on equine nutrition, what some common deficiencies are, etc I started looking to supplements for my horse today online - but many don't show exactly what is in it, at least from what I could see. Then I realized you could make your own supplements from real food, rather than just straight vitamins or extracts.
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.
