Be a Buyer: Support the Junior Livestock Auction Friday, July 22

Buyers can support a young person in their community by purchasing an animal at The Junior Livestock Auction. It’s the culmination of a year’s project for 4-H, FFA, and other youth organization members. As a learning and business venture, these young men and women have selected, fed, and groomed a steer, lamb, poultry, rabbit, goat, or pig. They have brought their project to the Fair to be judged, graded, and sold. Support of the auction translates into recognition and incentive for young adults to buy more animals and earn college funds—all while receiving practical training in business.
