Abstract
The expansion of the dairy industry in Idaho over the past two decades has impacted the supply and demand for feed crops in the State and Western U.S. This article presents a method for quantifying state level feed crop supply and demand on an annual basis. Results show that demand has exceeded supply for corn grain for the entire study period of 2003 to 2021, while supply and demand are largely at parity for alfalfa hay, corn silage, and barley. The extent to which feed demand is met by local or external supply has implications for risk management decisions for feed crop stakeholders in properly accounting for local production and external market risks.
