Excerpts from the report: Government participation in the pricing of fluid milk in the United States was inaugurated on a rather broad scale in the early 1930's. A number of States enacted legislation to stabilize milk markets in an attempt to raise prices for milk. The Federal Government entered the fluid milk pricing field following passage of the Agricultural Adjustment Act in 1933. Expansion of Government participation in milk pricing was slow in the late 1930's and little growth occurred during the 1940's. However, during the last ten years, the role of Governments in pricing milk has increased rapidly. As of July 1, 1962, a total of 83 Federal milk marketing orders were in effect in the United States. Dynamic changes in the production and marketing of milk are responsible for the increased demand by producers and other elements in the dairy industry for Government participation in milk pricing.
