After a turn judging the Ayrshires earlier in the day, Brittany Liebich, Mount McIntyre, competed for the young judges championship where she was announced the state winner.
Ms Liebich has been involved with cattle all her life, being born and raised on Boldview Farms Ayrshires.
"I am a calf rearer so I raise about 50-head a month and then milk every now and then, I also pick out breeding strategies for our own stock and show as much as we can," she said.
"It's weird not being at Adelaide doing the competition but at home I always get told that I have no idea what I am talking about but my sister judged the Holsteins today and she agreed with all my decisions so I guess I must have done something right.
"Its a good thing to get into and you learn things year on year and then you build on that as you go.
"I have taken a lot of my judging back to where I breed my cows and I am trying to breed the next champion at Adelaide (Royal Show)."
Ms Liebich said she is following the footsteps of her mum, sister and uncle as they are "pretty big influences".
"It's in my blood and this experience assists me to take after my influences and also helps to pick-up on what bulls people are using with their good show heifers today," she said.
"I can take that home and thoroughly search that bull and work on picking better bulls to put over our cows to improve traits."
"This is my first year doing actual judging at shows, I have only been in judging competitions at Adelaide for the past couple of years, I have never been to nationals for this.
"I am excited but really nervous, I'm not a person who likes to talk on microphones and I tend to doubt my judgement and then I second guess myself, but today was just gut instincts."
Runner-up Courtney Afford, Woods Point, said the competition is full of opportunities and anyone considering trying it, should definitely give it a go.
"A couple years ago there was no way I could stand up and do this," she said.
"Country shows are where to start, there is less competition but the judges can be more one-on-one with you and go through things.
"A lot of farmers if you go there, they'll teach you what they know and what a good cow is, there's plenty of ways to get into it and build on that."
After explaining his preferred choosing and it's similarities to the young judges picks overjudge, David Peglar, Sleepy Hollow Holsteins, Langhorne Creek, congratulated all competitors on their speaking.
"You have all come up here and had a crack and done a really good job with it," he said.
"The way you made specific comments on the quality of the heifers presented was exceptional for your stage of judging, when there were unusual differences."
