[QUOTE="1848, post: 114588, member: 1303"] I would bet BC runs a tight calving group. If not, then that is how you do it w/o knowing birthdates...with a limited exposure time of the bull! That way you know that all the calves are within say, 45 to 60 days of each other. If the cow don't get bred in your window, cull her. Get a weaning weight average..assuming you wean them all on the same day, and see who excceeds average. The older ones that do poorly would not make the average and therefore be culled anyway, ...despite not knowing the calving date. Just need to record which cow is not cutting the mustard, season after season to know which ones to cull. The cows with higher fertility should stand out in this type management too, as they will always calve earlier and therefore have the best chance at the bigger calves, unless they don't milk, then you know she ain't doing it there. So in the end you will have the cows which milk, raise a big calf and breed back on time. ;-) [/QUOTE]
