have the same problem as well, steer around 1225 but not eating well
In my case I think he's just burned out /done
Have tried everything .... Some are just not big eaters I believe
Have used steam flaked corn as part of ration in the past over the last 60 days or so.
May do so again this year.
Steer seems to be getting some decent cover on him now with the stabilized rice bran.
