The Gelbvieh grand champion male at this year's Royal Queensland Show was described by its owner, Julie Nixon, as "a very complete bull from the head right through to the tail".

Mrs Nixon, Weetalabah Cattle, Dulacca, said Weetalabah Vector had stood out ever since he was a calf.

"He's one of my favourite bulls," she said.

The 10-month-old bull weighing 434 kilograms was sired by Wbht207 and was out of Wbhq211.

His P8 and rib fat was 5 millimetres and 4mm respectively, and he had an eye muscle area of 87 square centimetres.

Mrs Nixon said his father was a champion, but unfortunately passed away recently.

"So this little fellow means the world to me...and will replace his dad (in the stud)," she said.

Mrs Nixon and her husband, Aderian, who also have a Hereford stud, started showing at the Royal Queensland Show 32 years ago.

"I saw the Gelbvieh when I was over in the (United) states and my parents had a commercial operation and they put Gelbviehs over their black baldy Hereford Angus cross," she said.

Mrs Nixon's favourites are the Gelbviehs while the Herefords are preferred by Mr Nixon and their daughter Aleacea.
