The Lincoln Red breed returned to the Royal Adelaide Show hoecker, one year after their debut.
Four Winds Tess, a half sister to last year's Lincoln Red champion, had its turn in the ring.
Judge Scott McKay, McKays Shorthorns, Newlyn, Vic, said the 16-month-old heifer had plenty of promise.
"She's clean through the shoulder with good spring of rib," he said.
"I admire the depth in the back end.
"She parades very well and is well put together."
Breeders Luke and Kay-Dee Menz, Four Winds, Red Creek, run about 15 breeding cattle, as the only SA Lincoln Red breeder - and one of 13 nationally - have been building their numbers in recent years, and showing them off.
"It would be nice to get another breeder in SA but we can't without people knowing what they are," Mr Menz said.
Ms Menz says the breed is very good to handle.
"We've got some at home that aren't halter trained and you can go up and give them a pat," she said.
"And they're dual-purpose - the mothers produce a lot of milk and the calves grow quickly, but they've got big frames and a lot of meat."
Ms Menz said they had hoped to bring more this year but had some animals ready to calve.
She said had an AI program in the works, with much of the semen available for the "endangered" breed, from as early as the 1970s or 1980s and from England.
