[QUOTE="wbvs58, post: 1530693, member: 16453"] Just to throw another question out there. Does the closed linebred herd suffer because it is not taking advantage of using the bulls that have stood out from their peers in respect to growth as lets face it there is not much measured other than kilos at weaning and yearling, scrotals and scan data before they are sold. Phenotype must go a long way to saying this is an exceptional bull. So the closed herd misses out on introducing this stand out improved genetic package. Is it to their detriment? Or is it a case that this new bull is truly an outlier and it is unlikely that he pass his exceptional growth on to his progeny as it requires all the stars to line up like having the right dam, the right environment and the season to duplicate the one he grew up in. Also, the big one that says a good calf, the weaning weight, is it his ability to grow or is it the cows ability to feed him. Both EPD's are calculated from the same measurement, the calfs weight at weaning? The cows milk output is never measured. Personally I operate similar to Ron, we both enjoy what we do now in our retirement. We both enjoy sampling genetics from well respected herds that have been around a lot longer than our herds and to see the resulting offspring in our herd. We both admire the work that breeders have done in these closed herds to produce an even line of cattle. What we do is never going to change the cattle industry of our countries but to us old farts it is nice to drive out in our paddocks and view the resulting eye candy so carry on with this discussion but don't tear strips off us we will continue doing as we do but it is great to hear this discussion.
