Three livestock exhibitors at last year's Ohio State Fair have been disqualified for allegedly outfitting their Holstein cows with hairpieces.

State Fair inspectors said the three glued or painted hair from another part of the animal or from another animal to create straighter backs on the cows and enhance their appearance in the show ring.

Kreg Krebs and his brother Kenneth of Fredericksburg, and Scott Long of Clayton, Mich., could be required to forfeit all winnings, said Department of Agriculture spokeswoman Melanie Wilt. The winnings had been withheld by fair officials.

Wilt said state inspectors at the fair discovered the fake hair when the cows were leaving the show ring.
