[QUOTE="robert, post: 1001002, member: 9171"] Right, you can have as much 'performance' as you care to support / feed, whether that is lbs of gain to weaning or yearling or if it is lbs of milk yield per cow/lactation. It is human nature to want more, there's no bragging rights for a 500lb weaned calf yet that may well be the optimal level to create the 1200lb mature cow. Most genetic evaluation systems reward the outcross, and conversely punish the within herd, potentially linebred herd where optimal levels of production and sustainability have been achieved within the environmental constraints and the goal is to perpetuate the herd with consistent production matched to resources.
