Three generations of the one family were involved in two of the champions named in the Guernsey show at International Dairy Week on Wednesday.
Tyson and Mark Shea and Neville Wilkie, Bacchus Marsh, Vic, are behind a Guernsey stud operation that has enjoyed considerable success at IDW for many years.
This year they showed the grand champion Rockmar Miami Graceful and the junior champion Rockmar Pilot Madison.
The six-year-old grand champion claimed her second grand champion title, having won the award in 2018 and being runner up in 2019.
Tyson said the cow was fully home bred on both sides of its pedigree by his parents Mark and Roxanne, who own the cow.
“The Gracefuls are one of dad’s original families – nearly every second cow we own is a Graceful,” he said.
“They have been good cows for a long time.”
