Dairy 2007: Part 2. Changes in the U.S. Dairy Cattle Industry, 1991-2007

摘要

In 1983, promoters of the concept that would become the USDAs National Animal Health Monitoring System (NAHMS) envisioned a program that would monitor changes and trends in national animal health and management. They hoped to provide periodic snapshots of U.S. food animal industries. With these industry overviews, members could identify opportunities for improvement, provide changing foundations for research and special studies, and detect emerging problems. Section I of this report shows demographic changes of the U.S. dairy industry from a historical perspective using data provided by the USDAs National Agricultural Statistics Service (NASS) and Agricultural Marketing Service (AMS). Section II shows demographic changes of the world dairy industry using data provided by USDAs Foreign Agricultural Service (FAS). Results of four NAHMS national studies in Section III complete the overview of change in the U.S. dairy industry during the 16-year period of 1991 to 2007.
