Cooperative livestock shipping associations have maintained their importance in the marketing of Iowa livestock since 1920. There were 697 associations in Iowa in 1925. They shipped 67,523 single-deck cars of livestock in 1924, which was 25 percent of all the livestock marketed.
Altho the number of livestock shipped cooperatively has increased since 1920, the proportion handled cooperatively has remained constant. About one-half of the farmers in the state used local shipping associations in 1924 to market at least part of their stock. The volume of business per association varied from 2 to 500 cars of hogs in 1924. Hogs were the most important kind of livestock handled, making up 84 percent of all cooperative shipments. Cattle formed 15 percent and sheep less than 1 percent.
