In 1990, Novakovic, Jack, and Keniston reviewed the milk production characteristics of states and regions of the United States.1 Recent milk production performance nationally was discussed using the USDA revised estimates of milk production, production per cow, and cow numbers by state and for the U.S. over the period 1983 to 1989. The majority of the earlier paper was devoted to a longer term analysis of milk production trends, by state, since 1960. This paper revisits and updates the discussion of national and state trends in milk production.
