NORM Weir aims to breed big framed, fertile sheep with as much quality wool as possible at his Kerrilyn Merino and Poll Merino Stud.
The Dunluce stud, founded in 1994 based on Belbourie and Wonga bloodlines, does this by using top Artificial Insemination sires.
Norm says all rams are tested and ranked for wool and body traits.
“We test the quality of our stud and effectiveness of the flock by entering wether trials,” he said.
“Both our flocks and clients’ flocks have been very successful in this venture.
“We are predominately a medium wool stud with microns ranging between 16.5 to 21.5.”
Norm said Kerrilyn had a history of breeding heavy-cutting productive sheep.
“We have won four most valuable fleece awards at the Australian Sheep and Wool Show Bendigo as well as a champion strong wool fleece and reserve champion medium and fine-medium fleece awards.” 
Benchmarking of Merino and poll Merinos - the poll stud was established with the purchase of 50 ewes and a ram at the Lewisdale dispersal sale rams and ewes in Western Australia in 2011 - has seen Kerrilyn awarded major prizes.
At last years’s Australian Sheep and Wool Show, had three big days being named reserve Champion strong August shorn ewe, most successful stud exhibitor in fleece show, Reserve Champion fine medium fleece, Reserve  Champion strong fleece and most valuable fleece in group four.
This year, there was more success - two broad ribbons, seven first ribbons, seven seconds, six thirds. “Our second placed medium wool rams fleece was the heaviest in the show which is our aim to have quality and quantity and our all purpose ram with a 42 muscle is representing our duel purpose aims,” Norm said.
And there was more success at last month’s Hamilton Sheepvention and Expo - Champion and reserve Champion medium Merino ram. Champion and reserve  Champion strong Merino ram. Reserve Champion  strong poll ram. Champion strong Merino ewe. Champion medium Merino ewe. 
Norm Weir strives for consistency coming out of his stud. The 2024 showing backed up last year’s successes that included Medium Wool Champion Merino Ewe and then went on to win Grand Champion Medium Wool Ewe, Champion Fine Medium Poll Merino Ewe and went on to become Reserve Grand Champion Fine Medium Ewe. The same sheep were also awarded the Fine Medium Wool and Medium Wool Ewe Victorian Champions. The Medium Wool Ewe then won the Victorian Bred Champion Wool Ewe of the Show
Kerrilyn’s fleeces have also received honours over the years including at the Australian Sheep and Wool Show winning the champion Victorian fleece in 2021 that followed from earlier success in taking out the champion medium fleece.
Kerrilyn also won the Stoeleigh Perpetual Challenge Cup (highest aggregate medium wool classes) with champion ribbons, four reserve champion ribbons, 10 firsts, three second ribbons, three thirds and a fourth place in the pairs at the 2023  Victorian Sheep Show in Ballarat.
At the 2025 show, Kerrilyn won won the medium wool aggregate and Reserve Champion medium wool Merino ram also champion March shorn strong Merino ram and 5 reserve Champions
