We used to feed our horses three times a day, but then I got a job and coudn't give the lunchtime meal, so we divided their ration into twice a day. Now that I'm home again, I'm going back to three times a day.
So... three times a day a flake of grass hay. Once it cools off for the winter, we'll give half grass and half alfalfa.
(Our young gelding gets a flake and a half since he's a big, growing boy. The baby only gets half a flake. For my mare, I only give her half a flake at lunchtime.)
They get a morning bucket with a scoop of Lakin Lite pellets, a scoop of Equine Senior, and a multi-vitamin supplement. My mare only gets half the pellets and half the Equine Sr. Because she gains weight breathing air, and she also gets a joint supplement.
