The exhibitors of a Simmental-Angus steer were "euphoric" after it was named grand champion steer on hook in the Royal Adelaide Show led steers competition.
LCS Timmy T055, a crossbred export weight steer, shown by Lancaster Simmentals, Field, was announced the winner at an evening awards ceremony.
Prue Cartledge, Lancaster, said the family, made up of Henry, Tim, Lise, Lizzy, Harry and Duncan, had been entering the competition for the past eight years, including winning an eating quality competition in 2021, but this was their biggest prize.
"Our kids love entering the steers in the competition, and they take them to the (SA Junior) Heifer Competition in July," she said.
"We figured, we'd done all that work so we might as well go on to enter the steer competition."
She said the steers were a passion project for the family.
"It's what they love, it's what gets them out of bed in the morning," she said.
The Black Simmental-Angus steer, which had a liveweight of 614 kilograms, and scanned an eye muscle area of 117 centimetres squared, P8 fat of 13 millimetres and rib fat of 12mm, scored 88.01 points - out of a possible 100 - in the carcase component.
