Cattle do in fact perform sex much like humans.
The bull mounts the cow (without injuring her).
A single bull can in fact impregnate numerous 
cows and will often have intercourse with the
same cow more than once (this increases the
chance for impregnaion obviously).  Having lived
on a farm, this knowledge is from experience.

Question:  Isn't the bull able to determine if
he has had intercourse with the cow by smell and
can he also determine if the cow is pregnant in
the same fashion?
