Pelvic measuring is a "hot" stat used on bull tests. But, if you pick cattle for large pelvic measurements, you are slowing increasing the size of your herd, because, naturally, larger cattle have larger measurements. The best use of PM is for the outlying animals - exceptionally big for their size - or too small (causing calving difficulties).
We do not check out cattle. Like Dun, my husband can pretty much tell at breeding time if they are potential problems. But, in all our years of calving, I think we only had one female with a (too) small pelvic area.
