All three Scottish tourists are included plus 11 Welshman, five Irishmen - Paul O'Connell, Cian Healy, Jamie Heaslip, Conor Murray and Jonathan Sexton - and four Englishmen.
The six former Lions in the squad are Adam Jones, Mike Phillips, Jamie Roberts, Alun Wyn Jones, Heaslip and O'Connell who will captain the team.
Tour manager Andy Irvine said: "After all the pre-tour preparation in Cardiff and Dublin the match against the Barbarians on Saturday marks another milestone in the proud history of the Lions and the start of the 2013 tour.
"This is the important first match of a 10-match tour and the players are eager to get the tour off on the right note.
"Training has gone very well and it is exciting to see 11 players making their run-on debuts for the Lions, including the tour's youngest player Stuart Hogg."
Head coach Warren Gatland said: "I am really excited by the first selection of the tour. Naturally it comprises largely those players not involved in last weekend's Aviva Premiership and RaboDirect PRO12 finals and we have a lot of players making their debuts for the Lions.
"At the same time we have a hard core of experience with the six former Lions sharing 430 caps between them and 19 Lions Tests.
"There are also some proven combinations such as the Welsh centre pairing and back row. Some of the boys who played last weekend are on the bench as cover and generally everyone in the camp is raring to go."
The opening match of the 2013 tour will be broadcast live on Sky Sports 1HD, while there will also be live radio commentary on a special edition of RTÉ 2fm's 'Game On' on Saturday afternoon.
Meanwhile, there are two provincial players in the Barbarians' starting line-up for the much-anticipated clash - Jared Payne of Ulster will start at full-back with O'Connell and Murray's Munster team-mate Casey Laulala lining out at inside centre.
