Swine 2006 Participating States

 The U.S. Department of Agriculture’s NAHMS 

conducts national studies on the health and 

management of America’s domestic livestock 

populations. These studies are designed to meet 

the information needs of the industries, as identified 

by people working within these industries. 

The upcoming Swine 2006 study will be NAHMS’ 

fourth national study of the U.S. swine industry. The 

first study, the 1990 National Swine Survey, 

focused on health and health management of 

farrowing sows and preweaned piglets. Swine ’95 

was NAHMS’ second swine study and provided an 

in-depth look at over 90 percent of the U.S. swine 

herd, focusing on the grower/finisher phase of 

production. NAHMS’ third national swine study, 

Swine 2000, provided valuable data on nearly 94 

percent of the U.S. swine herd on operations with 

100 or more pigs. 

_____________________________________ 

By gathering reliable and valuable information on 

the U.S. swine industry, Swine 2006 will help to 

• Define and evaluate current 

management practices and trends in the 

U.S. swine industry, 

• Help legislators and industry make Swine 2006 Study informed decisions, 

• Assist university researchers and private 

enterprise to identify and focus on vital 

issues related to swine health and 

production, and 

Seventeen States will participate in the Swine 2006 

study (see map). These States account for 94 

percent of both swine operations with 100 or more 

pigs and inventory on those operations. The 

objectives of Swine 2006 include • Conduct economic analyses of the 

health and production of the U.S. • swine industry. Describing swine management practices 

used during the gestation, farrowing, 

nursery, and grower/finisher phases of 

production, 

Participation in all NAHMS studies is absolutely 

voluntary. Selected producers that choose to 

participate in the Swine 2006 study will be visited 

by representatives from the National Agricultural 

Statistics Service between July 17, 2006, and 

September 15, 2006. An on-site questionnaire will 

be administered during this visit. Producers that 

choose to continue in the study will be visited twice 

by veterinary medical officers (VMOs), who will 

administer questionnaires and take 

• Determining the prevalence and risk factors 

for a variety of pathogens found in nursery 

and grower/finisher pigs, 

• Examining vaccination and antimicrobial –

use practices, and 

• Providing an overview of changes in U.S. 

swine management and health from 1990 

through 2006.

biological/environmental samples. VMOs will make Confidentiality 

their first visit between September 5, 2006, and 

November 17, 2006, and their second visit between 

December 4, 2006, and February 28, 2007. 

Because NAHMS’ studies rely on voluntary 

participation, we protect the privacy of every 

participant in the following manner: Only the data 

collector knows the identity of the respondent. No 

name or address is ever recorded in any database. 

No data will be reported on any individual or in a 

manner that would allow the identification of an 

individual. 

Testing Options 

Individual results will be returned to participants, 

although results may not be available until the 

study is completed. 

• Porcine Reproductive and Respiratory 

Syndrome (PRRS)

the national swine herd and collect blood 

from up to 35 finishers from each operation.

• Swine Influenza (SIV) 2150 Centre Avenue

(new and traditional strains). Blood samples 

from animals not vaccinated for SIV can be 

tested for flu.
