This chapter provides some historical background to the discussion of the current status of the various segments of the U.S. sheep industry in subsequent chapters. As well, the chapter provides an overview of the linkages and interdependencies in the industry inherent in the marketing channels or value chain through which sheep and lamb products flow from producer to end user.
