List of union stockyards in the United States

Union stockyards in the United States were centralized urban livestock yards where multiple rail lines delivered animals from ranches and farms for slaughter and meat packing.

A stockyard company managed the work of unloading the livestock, which was faster and more efficient than using railway staff.

[1] Terminal stockyards received, handled, fed, watered, weighed, held, and forward-shipped commercial livestock.

[5] Stockyards mostly handled cattle and pigs for beef and pork production, but occasionally served as waystations for other animals.

For example, around 1934 a dozen American bison from Colorado headed for Santa Catalina Island were held at the Los Angeles Union Stock Yards before boarding the ferry for their final leg of the trip.
