Most folks rely on VPN and host security to make sure the zone gets
to the master okay (if "valid" means uncorrupted). After that you
have the option of TSIG covering XFR's or you can use some protected
non-DNS-standard (yet widely popular or some-other-standard) means of
replicating the data on each server.
I.e., most deal with such a threat (corruption between the signer and
the server) via prevention instead of detection. Partly because the
preventative measures are already in place for other institutional
activities (like protecting the web server).
If you mean "valid" as in syntactically correct, folks rely on BIND
to tell them. If you mean complete, then you can do use file
checksums. There are many ways to define "valid" come to think of it.
More or less, the DNS protocol engineers punted that question to the
host security and operations staff people.

Think glocally. Act confused.
