In the "old days", it was always said not to keep replacement heifers out of first calf heifers. This is NO LONGER true. Used to be, heifers were bred to small, dink bulls, so that they didn't have calving problems. Now, with EPD's and better genetics, there is absolutely no need to breed heifers to dink bulls. By all rights, your heifers SHOULD be producing you the best genetics in your herd, if you are breeding cattle not multiplying cattle. Yes, a calf out of a heifer may be a little lighter weight than out of a mture cow, but the genetics should be better if you improve bulls each time.
As far as over conditioning heifers, the biggest problem is that every mammary cell that is filled with fat PRIOR to breeding, will NEVER produce milk. If an open heifer develops fat in her udder, she will NEVER be a good milk producer (at least never be as good as she should have been).
I would NEVER consider culling our heifers out of heifers. They have an equal shot at becoming a replacement as one out of a cow.
