The cow's back turns out to be quite a bit more robust than
your ability to imagine the event.  It should not be too hard
too find someone who will permit you to watch the next time
a prize bull or stallion is studded out.  (Someone has to
watch to determine whether or not the studding fee is due in
the event that the cow or mare does not become pregnant.)
The cow (or mare) only supports a fraction of the bull's 
(or stallion's) weight, because the male animal moves into a
somewhat hunched over position with a large portion of its 
weight shifting to its rear legs.

Beats the hell out of me.  Maybe you should call a zoo.
