Abstract

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.
美国畜牧生产的变化,1969- 1992
本报告从产业集中度和结构的角度考察了1969- 1992年美国畜牧业生产的地理变化。从1969年到1992年,农场数量下降了30%,但生猪和奶牛养殖场下降了70%,鸡蛋养殖场下降了85%,肉鸡养殖场下降了35%。从1978年到1992年,饲养牛的业务下降了40%。尽管农场减少,但大多数商品的生产总体稳定,其变化反映了消费者对畜产品需求的变化。由于生产更多产品的农场较少,大多数主要牲畜商品的生产结构发生了重大变化。然而,变化的幅度和地理位置因商品而异。
