Do cows give birth the same place they potty?

If given a choice of where to go, most cows are really good about not doing this. They will find a secluded and clean spot to give birth on, away from the usual feeding and defecating areas other cows would be found. However, if they are confined to a feedlot or in an area where a producer has failed to clean out the area the cow is to calve (which doesn't happen all that often) a cow may have no choice but to do so.
