This document provides an introduction and overview of the complex challenges facing the modern dairy industry. It discusses the various players in the dairy supply chain and then outlines several key areas of complexity, including external pricing systems (such as price supports, import restrictions/quotas, and marketing orders), evolving public policies, and shrinking margins due to high input costs and the milk-feed ratio. The document serves as a primer and baseline for further examining issues like domestic/global competition, processing complexity, and new technologies that could provide competitive advantages.
