Like everyone else, I appreciate the fleshing ability, the depth and capacity of the second brood cow.
However, I judge a cow on what she produces; a cow must be able to breed as good as herself or better (hopefully better). The first cow with the heifer calf, have produced an outstanding daughter. The second cow with the bull calf has, IMO produced an average bull calf.
So to me, the first cow is the better one.
