As part of the National Animal Health Monitoring System (NAHMS), the USDA:APHIS:Veterinary Services (VS) conducted its first national study of the swine industry with the 1990 National Swine Survey. Study results provided an overview of swine health, productivity, and management for 95% of the US swine herd, the population represented by the 1,661 participating producers. The National Swine Survey focused on farrowing sows and preweaning piglets.
NAHMS’ second national swine study, Swine ’95, was designed to provide both participants and the industry with information on over 90% of the US swine herd.
This is the third of a series of reports from the NAHMS’s Swine 2000, study. For this report, data were collected from December 1, 2000, through February 28, 2001, from 799 swine production sites.
