Mr Miller was returned unchallenged, with Fife arable farmer Allan Bowie and fellow livestock producer Rob Livesey as his vice chairmen. Mr Bowie has been vice president since February 2009, while this will be Mr Livesey's first year in the post, having taken the space vacated by arable sector firebrand John Picken.
The union has a fresh look to its board of directors for 2013/14, with a number of new regional chairmen and committee leads joining the top table.
Mr Miller, who chaired the first board meeting of the new term, said: "This board takes up office at a hugely important time for the industry, with the CAP reform process and independence debate gathering momentum. In addition, every sector of our farming industry faces a growing list of challenges.
"This is a team with the skills and knowledge to meet those challenges on behalf of our members. However, 2013 will also be a year of celebration as we mark our centenary. This board, with its wealth of experience and enthusiasm, will create a great platform to drive the union into its next 100 years."
