His birthweight is a 78 so he's not a cow killer but I wouldn't give her alot of feed if I did it, could possibly work on a pasture heifer that's not being hauled, but then again there is safer bets than running a risk
He makes them way to stout boned and big hipped for me to ever think about putting him on a heifer. Be patient and use a proven Calving ease bull purebred and pray for a female or a clubby with more angus and Maine influence
