I'm using transactional replication in SQL Server 2012. Is it possible to replicate user-defined data types by adding a new column in the replicated table?
There are custom data types Datatype_1 (varchar (10)).
After adding a column with:
alter table Table_name
add test_coll Datatype_1 null
As a result, we have:
Option "Convert data types" in article properties is set to "false".

As far as I know, you cannot add a user defined datatype to subscriber by simply add a new column to publication once publication is created. After publication is created, you need to manually recreate user defined datatype on each subscriber in order to use it. Also, changes made to user defined datatype will not be replicated to subscriber.
For more information, please review MSDN Article.
If you have any other questions, please let me know.

Newly added columns on the publisher with a user defined data type are converted to the base data type.
If is only when the snapshot is generated that the user defined data types are not converted to the base data types if the convert data type setting is set to false.
Note that the user defined data type must already exist on the subsriber for the snapshot to be applied.
