Best I've done adj. 205 746 lbs. and yearling adj.weight 1300 lbs. now at 14 months 1691 lbs. Has been fed since weaning. Nothing but mom up to weaning and grass.
Even with EPD's the numbers are only as good as the man who turns them in. I have always tried to be as acurate as I could be. I do know some who guess at birth weights and also lie about those 120 lb bull calves.
