Agriculture Secretary Russell Redding says the sculpture unveiled Thursday highlights the careers and roles the dairy industry plays in the state.

The sculpture features renderings of a cow and a farmer, an agronomist, a milk processor and a shopper with a basket full of products.

The butter came from waste scrap butter unsuitable for human consumption. After the show, the sculpture will be taken to a farm and turned into energy in a methane digester.

The Pennsylvania Farm Show is the nation’s largest indoor agricultural event, featuring 12,000 competitive exhibits, more than 5,200 of which are animal competitions. It runs through Saturday.
