Swine 2006: Part 2. Reference of Swine Health and Health Management Practices in the United States, 2006

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, thereby providing periodic snapshots of the 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. The Swine 2006 study is NAHMS fourth national study of the U.S. swine industry. Seventeen States participated in the Swine 2006 study (see map below). These States accounted for 94 percent of swine operations and inventory on operations with 100 or more pigs. A random sample of 5,000 swine producers was selected to be visited by representatives from NASS between July 17 and September 15, 2006. An onsite questionnaire was administered by NASS enumerators during this visit. Results from the first data collection period of this study were presented in Swine 2006 Part I: Baseline reference of Swine Health and Management, 2006. Part II: Reference of Swine Health and Health Management in the United States, 2006 is the second of a series of reports from the NAHMS Swine 2006 study. Data for Part II were collected from 514 swine production sites between September 5, 2006 and March 15, 2007.
