The Union Stockyards of Omaha, Nebraska, were founded in 1883 in South Omaha by the Union Stock Yards Company of Omaha. A fierce rival of Chicago's Union Stock Yards, the Omaha Union Stockyards were third in the United States for production by 1890. In 1947 they were second to Chicago in the world. Omaha overtook Chicago as the nation's largest livestock market and meat packing industry center in 1955, a title which it held onto until 1971. The 116-year-old institution closed in 1999. The Livestock Exchange Building was listed on the National Register of Historic Places in 1999.
