TIMING is everything when buying top Jerseys - just ask David Weel.

"I was driving up here, my mate took a photograph - he didn't think I would make it - (but) I walked into the shed just as she went up," the 22-year-old said.

David, who works on a 500-head dairy farm at Port Campbell, paid $13,000 for 10-month-old Jersey heifer Adadale Action Passion at International Dairy Week last week.

He also bought 11-month-old Holstein Southern Star Tonio 2 for $6500 the following night at the Semex Spectacular sale.

They are welcome additions to his Blueprint stud of 30 head - mostly Holsteins. David liked the look of the Jersey heifer's mother at the Brisbane Royal Show last year, where she won reserve champion.

David described the dam, Brunchilli BRC Passion EX90, as a "big square cow". He particularly liked that she would improve with time.

"(There are some) two year olds that look mature as two year olds," he said. "(But) she's a cow that would develop into the future."

Last year David paid $12,000 for Holstein Warwick Farm Goldwyn Lustrious at IDW.

Living up to his stud name, Blueprint, David is laying plans for the future, trying to build a herd with different cow families in the hope of moving into share farming or managing a farm.

This year he wants to increase numbers from Canadian Jersey embryos he purchased from Rapid Bay.

The attraction to stud cows is based on David's interest in showing.

"I don't mind milking cows but showing is an added bonus, something to look forward to," he said.
