I just called the DWR today, asked them when I should expect the results. The lady told me that the results are posted about June the following year. You can check the results at wildlife.utah.gov. Click where it says "drawing history and harvest reporting" (under "Information" on the home page). After you log in, click on the tab "My harvest survey", then "view". When the results come back, the bull's age will be listed at the bottom.
It kind of sucks that it takes so long for the results to get back, I'm interested in knowing the age of my bull. I've been logging in and checking it almost everyday, then I finally called the DWR today.
