If the steer is 1,500 pounds, it’s time he went to that great cattle pasture in the sky. He’ll dress about 750 - 800 pounds, which makes nearly 400 pounds to the side and that’s a lot of beef. Is he fat? He might need to put on a little fat, so your friend should give him more grain than usual for a couple of weeks. Sometimes cattle do better in pairs, anyway, so if your friend does raise beef again he should get two.
Oops, real life has just intruded, gotta go. Be back.
