The event is recognized as the world's largest purebred livestock show with more than 23,000 entries and nearly $700,000 in prizes and awards.
The event is scheduled for Nov. 5-18, and will take place at the Kentucky Exposition Center, Louisville, Ky.
Both Ethan Stevenson and Paige Stevenson, Brazil, entered one head of market hog in the swine division of the event.
Both Ethan, 18, and Paige, 16, are the children of Alan and Betsy Stevenson.
Purebred farms from nearly every state and Canada bring livestock to compete in one of 10 expo divisions, including dairy cattle, dairy goats, meat goats, beef cattle, quarter horses, draft horses, mules and donkeys, sheep, swine and llamas and alpacas.
More than 200,000 American and foreign visitors attend the hundreds of individual breed shows, sales and events. In addition to the recognition and prize money that comes with winning at the event, the value of the champion breeding stock is enhanced.
Breed association events are not the only NAILE feature. The expo is also home to numerous youth events that are part of the livestock industry's tradition, including Eastern National 4-H Horse Roundup, Youth Junior College and Senior Collegiate Dairy Judging Contest, Dairy Quiz Bowl, National Collegiate Livestock Judging Contest, National 4-H Livestock Judging Contest, Junior College Livestock Judging Contest and National 4-H Poultry and Egg Conference.
