Sheep 2001. Part 1: Reference of Sheep Management in the United States, 2001.

摘要

As part of the National Animal Health Monitoring System (NAHMS), the USDA:APHIS: Veterinary Services (VS) conducted its first national study of the sheep industry with the 1996 NAHMS National Sheep Survey. NAHMS' second national sheep study, NAHMS sheep 2001, was designed to provide both participants and the industry with information on the U.S. sheep flock on operations with 1 or more sheep. Specific objectives of this study are described in Section II: Methodology. The USDA's National Agricultural Statistics Service (NASS) collaborated with VS to select a sample (of producers) statistically designed to provide inferences to the nation's sheep population in the 22 participating states (see map). These 22 states include the major sheep producing states, accounting for 87.4 percent of the January 1, 2001, U.S. sheep inventory and 72.3 percent of U.S. sheep producer.
