In addition to its supreme champion title and Stock Journal Publishers grand male and female champion prizes, the stud also won all bar two of the male and female age championships.

The depth and quality of EP Cambridge's animals was evident, with five reserve champion ribbons.

Stud principle Matthew Lloyd was thrilled.

"The most pleasing thing is that our champions come from nine different sire lines," he said.

"It means we have a spread of lines and we're not just relying on one or two successful lines, which gives us greater breeding options."

EP Cambridge Dealbreaker's supreme champion win comes in the senior male's first Adelaide show since junior level.

"He's the densest animal we've ever had, and what makes it so satisfying is that density is the hardest quality to breed for," Mr Lloyd said.

Judge Darryl Bishop faced a difficult decision when selecting between EP Cambridge Dealbreaker and On A Roll for the supreme champion title.

"These are two superb animals, however, I feel that the male is a fraction more outstanding than the females in breed type," Mr Bishop, Osory Angora Stud, Twelve Mile, New South Wales, said.

"He is extremely dense and well covered-in, which is what you are looking for in order to protect the fleece."

Mr Bishop was also particularly impressed by EP Cambridge On A Roll, labelling the adult female the "complete picture"'.

"She really has it all and is definitely densest female in the class," he said.

"With her balance between the fleece and her confirmation, she's the right type of animal I'm looking for."

Since starting their alpaca stud in 1993, EP Cambridge had established itself as "one of the world's largest studs".

"We certainly love what we're doing, and we're lucky that we got in at the right time to buy high-quality animals that really helped set us up," Mr Lloyd said.

In addition to its 3500-head Australian operations, based on the Lloyd family's 324-hectare Oakbank property, EP Cambridge Alpacas has expanded into Britain with a 1500-head flock.

"About five years ago we established our base over there, and it now means we have access to the whole European market," Mr Lloyd said.

But he remained adamant about the quality of local animals.

"Australia is breeding the best alpacas in the world, and there's nowhere else you could go and see such high quality animals."

A total of 20 exhibitors entered 120 animals in Huacaya classes, down from 169 last year.
