The advantage to longhorns is you don't have to feed them much for them to stay healthy, mine only get cubes if I have to get them up. I rotational graze so they're easy to handle without feed, the biggest problem I have with mine is they like to be too close with the big horns. I feed decent quality hay in the winter, last winter they only ate 3 bales each with me keeping hay out in front of them at all times and they stayed fat. I generally make all my animals clean up what's on the ground after the bale is gone with in reason before putting another out, usually one day without a bale in the feeder and they clean up what's still good on the ground.
