FH:
The processor should be able to tell...if not, to be safe, I'd tank the muscles surrounding the break (if it's front leg, won't be much, back leg, would be the round, dependent upon where broke, if up high for example.)
One thought however, because of the new (as of '04) rules regarding the harvest of non ambulatory cattle (commonly called downers) the slaughter of such livestock is now prohibited. Cases like this are tragedies of these new regulations. So, especially if your processor is inspected (in North Dakota they have custom exempt slaughter) they may not take the bull for processing because it's "illegal."
Sorry you're having a rough day...hang in there kid...it'll get better.
Cheers-
