【 摘 要 】

This report examines geographic changes in U.S. livestock production during 1969-92 from the standpoint of industry concentration and structure. Farm numbers declined 30 percent from 1969 to 1992, but hog and dairy operations were down 70 percent, farms producing eggs dropped 85 percent, and broiler operations declined 35 percent. Operations feeding cattle declined 40 percent from 1978 to 1992. Despite fewer farms, production was generally stable for most commodities with changes that reflected shifts in consumer demand for livestock products. With fewer farms producing more product, structural change in the production of most major livestock commodities was substantial. However, the magnitude and geography of change varied by commodity.
