Now most cattle auctions are their own commission company. The Springfield yards had several commission companies, so you basically had 5 different cattle auctions in the same facility and you could sell through whichever one you wanted to. They sold on a rotation basis. Anguscowman has it right on how it worked. I am thinking it is the same at Oklahoma City. Some people did not feel they were treated properly at Springfield, so it opened the opportunity for many cattle auctions to be built in the area. There were approximately 20 new barns built and this led to the Springfield yards going to almost nothing and then being sold. The owner of Joplin Stockyards bought Springfield, Tri-State, at Diamond and others. There was a large national group that was going to monopolize the cattle auction business at the time and this was an effort to put together the sw Missouri auctions to sell to them. The group sold stock and their stock was worth 80 dollars per share and then it went to nothing and went bankrupt. Joplin's owner, then closed Tri State and Springfield and now runs all of his auction out of Joplin's facility. A group of the Springfield commission company owners got together and built a fantastic, modern barn at Brookline, Mo on I-44. They do not use the multiple commission company approach and are very successful.
