Young sheep have dominated the ultrafine wool section in the Sydney Royal Show Merino judging, with both the grand champion ram and ewe showing less than two teeth.
Ultrafine judge James Rayner, Pomanara, Sally's Flat, said the two young sheep got up because of how they compared to the older ewes.
"They've got their whole life in front of them, where with the older ewes what you're seeing is what you're getting but for the younger ones coming through, they're only going to get better," Mr Rayner said.
"With my judging first impression is what I go for and when I saw both the winning ram and ewe in their class I knew they were going to go right through."
Grand champion ultrafine ram went to Conrayn Park, Berridale from the March shorn, not more than two-tooth class.
Mr Rayner said at only 14 to 15-months-old the ram had a promising future.
"For his age his stretch of body, his structure and sire outlook is very impressive and he's going to go on to be an impressive sire," Mr Rayner said.
"But on the day his wool was exceptional, his undercarriage, belly, down his legs is as pure as it is on his topknot and he's a true indication of where the ultrafine ram sires should be."
Peter Lette, Conrayn Park said the ram was sired by Conrayn Ford, the 2016 Grand Champion at the Australian Sheep and Wool show in Bendigo, Victoria.
It had a fibre diameter of 16 microns, standard deviation of 2.7, co-efficient variation of 16.9 and comfort factor of 99.9 per cent.
The Grand Champion Ewe was from Grathlyn, Hargraves out of the March shorn, not more than two teeth class.
"Her bonnet is exceptional, the carriage of wool down her legs and onto her belly is just exactly what I was looking for today," Mr Rayner said.
The ewe was one of their few sired by New Zealand ram Blairich 316 and had a micron of 15.8, SD of 2, CV of 12.7 and CF of 99.9 per cent.
Grathlyn took out first place ribbons in five ultrafine classes.
Bocoble Stud, Mudgee were also represented well in ultrafine with both the reserve grand champion ram and ewe from Bocoble.
The reserve champion ram came from the March shorn, six teeth and over class and the reserve champion ewe was from the March shorn, not more than four teeth class.
