Their Holstein, from their 500 head herd at East Logan, came out on top in the hotly-contested category.
The second calver, Eedy Crushabull Acclaim by Oh-River-Syc Crushabull was Super Heifer at Agriscot and reserve supreme at Dairy Expo.
She calved at the end of January and is classified VG89 giving 55 litres and was bought from Robert and Jason Helen in Southern Ireland last July.
Taking the reserve ticket was the Jersey champion, a second calver from the Cowhill Trust, Holywood, Dumfries, Kerricks Dakota Belle by Clydevalley Dakota. She was champion and reserve interbreed at Ayr.
There was further success for the father and son combination of Brian and Michael Yates in the British Red and White section when their second calver, Grayridge Addison Seisme Red by Farnear Aria Addison won the championship.
She calved in February, is classified 87, giving 50 litres and was being shown for the first time.
In the beef section, the British Charlois championship was won by Richard McCornick of Barnbackle Farm, Lochfoot with his 15 month-old bull, Ricnick Thor by Goldstar Gentleman out of Ricnick Precious.
Ricnick Thor was champion at last month’s Cumberland Show at Carlisle.
There was no championship luck for local breeders in the Galloway and Belted Galloway sections as there normally is.
In the Galloways the red ticket went to Catherine MacGregor from Blair Drummond, with the two-year-old bull, Moss Fayjock by Blackcraig Yahoo out of Blackcraig Fay.
The reserve champion was a two-year-old heifer from John and James Graham and former Lockerbie stockman, Dennis Gall from Blair Drummond.
The British Blue championship did come south and it went to Ali Jackson from Annan with the 13-month-old bull, Topgun Splash by Engin D Hontoir out of Solwayview Oesha.
Topgun was also the male champion before going on to win the overall championship and was reserve at Cumberland and Lesmahagow shows as well as taking first at Agri Expo.
Hugh Ramsay’s heavy horse pairs entry from Millisle, Garlieston driven by Elaine Ramsay took second place in one of the biggest entries in this section.
Dumfries sheep farmer Ben Radley enjoyed another successful show when he won the Charollais championships before going on to lift the reserve interbreed title.
Ben from Loaningfoot, Dumfries, just failed to emulate last year’s double success when he won both the breed and the interbreed championships.
But there was further success on Sunday for Ben’s shearling ewe Loaningfoot Abracadabra when she teamed up with her sire and winner of the male championship from the breed classes, Foxhill Va Va Voom, to take the interbeed pairs title.
Foxhole is a three-shear ram from the Ingram family, Logie Durno, Inverurie.
The interbreed pairs competition is made up of the male champion and lead female from each breed and judge Keith Brooke from Carsecreugh, Newton Stewart, had the difficult task of placing them.
Abracadabra is a Foxhill Vavavoom daughter, out of a Foulrice ewe, and she was inter-breed sheep champion at Ayr Show.
Robbie Jackson of Rigghead, Dumfries, won the championship in the Dutch Spotted classes with a gimmer bred by M and R McCornick, Barquhill, by Westbroad Diego, out of Kilroot Cinnamon.
The show saw a record attendance of 217,000 over the four days of the event with a huge entry of just over 2,000 sheep out of the total of 5,000 cattle, sheep, horses and goats.
