MADISON, Wis. -- The aging cattle barns at World Dairy Expo are about to give way to state-of-the-art livestock pavilions.

As World Dairy Expo has grown, so have its needs, Dane County (Wis.) Executive Joe Parisi told reporters Thursday afternoon. One of those needs, he said, is to replace the cattle barns.

Two new pavilions ― one 90,000 square feet and the other 180,000 square feet ― will house a variety of animals during livestock shows on the Alliant Energy Center grounds where the World Dairy Expo is held. The buildings will also have meeting facilities, equipment displays and concessions.

Large-scale cattle shows, like those held at World Dairy Expo, will continue to take place in the Coliseum near the construction site. But smaller-scale livestock shows can be held in the new pavilions.

The new complex will be known as the New Holland Pavilion at the Alliant Energy Center.

New Holland, a leading manufacturer of tractors and hay tools, secured naming rights through a partnership agreement with the Energy Center and Dane County.

New Holland is thrilled to have its name on the buildings that will house some of the world’s elite dairy animals, horses and other livestock, said Abe Hughes, vice president of New Holland North America.

Construction is scheduled to begin next April and completed in time for next year’s World Dairy Expo.
