My barrel horse mare is currently on hay and sweet mix. I got this hay from the pasture next door only because it was convenient, but she doesn't seem to like it all that much. I am looking to buy more, but this time go with Bermuda or Fescue which are both readily available in my area. Which has more nutritional value? Also should I start feeding her one flake of alfalfa in the spring for more energy when we race again?
