Not with those three primary directives.  A modern BIND name server ignores 
out-of-zone data, e.g., you can't have a mydomain.net record in the 
mydomain.com zone data file.

Instead, do something like this:

primary mydomain.com db.mydomain
primary mydomain.net db.mydomain
primary mydomain.org db.mydomain

Note that all three zones load from the same file.  For this to work, you 
can't use any fully qualified domain names on the left side of resource 
records.  So you need db.mydomain to look something like this:

@    in soa blah blah blah
         ns ns1
         ns ns2
         mx 10 mail
         a  1.2.3.4
www     cname @
ftp     cname @
mail    a  2.3.4.5

Just keep in mind that the origin of this file will be treated differently 
depending on which zone the name server is interpreting it as the zone 
database file for.
