The task of placing around 5000 head of the country's top cattle, sheep and horses will be in the hands of experts from all over the UK and Ireland, including one judge from France - Yves Lacroix of Mirecourt, who will place the Texels.
The overall supreme champion will be selected by Ian Anderson, of Dalcrest, Cumnock, while in the dairy rings Gavin Lawrie, of Brieryside, Sandyford, Monkton, will decide on the overall champions.
Other inter-breed beef judges include Friar Thomson, of Balymyle, Meigle, who will handle the team championship; Robert Adam, of Newhouse of Glamis, Forfar, who will judge the beef breeder and junior inter-breed; and David Murray, of Wolflaw, Forfar, who will judge the beef pairs.
In the sheep lines, Angus Kennedy, of Broughton, Biggar, will have to choose an overall individual champion from some 24 breeds, while the pairs and young handlers will be judged by Allan Wight snr, of Midlock, Crawford.
In light horses, Joyce Coltart, of The Stables, Tour, Kilmarnock, will be judging The Queen's Cup.
Also in the horses, the popularity of the HOYS Mountain and Moorland Under Saddle qualifier has required that the section be split into small and large breeds, requiring four judges as opposed to the usual two.
Supported as ever by the Royal Bank of Scotland, the show will take place at the Royal Highland Centre, Ingliston, Edinburgh, on June 19 to 22.
