Why Mineral Blocks are So Important For horses

Am I missing any nutrients for my horses? I give them grain and hay - isn't that enough? I am sorry to say this but no, it isn't enough because grain and hay don't have all the minerals that a horse needs. Out in the wild they eat a variety of plants that give them all the minerals they need. But don't fret, there is a fix to this problem. Any guesses? Yes!!! It is a mineral block! I know that it is more money spent on your horse. But your horses will thank you if you do.

below is a picture of the mineral block that I use with my horses.
