New rules adopted for this year's fair in West Allis expands the auction to include all champion beef, swine and sheep, regardless of breed. That will boost the number of animals to 27 or 28.
Last year, former Governor Scott McCallum sold 20 animals at the Blue Ribbon Livestock Auction for nearly $245,000.
The fair's auction committee will take a bigger bite of the winning bids so it can increase its scholarship and award fund. It'll take five percent more, now at 20 percent.
DNA analysis will be used for the first time to ensure animals brought to the fair are the same ones weighed and registered for the competition in the spring.
Gov. Doyle makes his debut as auctioneer in the Coliseum show ring at 6:30 Wednesday evening.
