Movement data

Across the U.S. swine industry, animals and other products (such as semen and germplasm) are transported between farms and states. RABapp™utilize such data to build detailed, transportation networks Figure 1 for contact tracing, risk calculations, and outbreak simulations.

Diagram showing the direct and indirect contact chains between farms. Direct contact chains are direct connections between two farms (e.g. Farm A and Farm B have a direct contact chain); indirect contact chains involve multiple farms (e.g. Farm A and Farm B also have an indirect contact chain via Farm C).

Farm type classification

The RABapp™ follow the US SHIP farm type classification. See table below.

Farm type Description

Breeding Herd Production site with breeding females and house >= 1,000 breeder or feeder swine. (e.g. breed-to-wean, breeding/gestation or farrowing only, with or without on-site gilt isolation/grow-out).
Growing Pig Production site with >= 1,000 feeder swine (nursery, grower, or finisher).
Farrow to Feeder or Farrow to Finish Production site with breeding females, grow feeder swine for purposes other than breeding stock replacement for this particular farm site, and house >=1,000 breeder or feeder swine.
Small Holding Production sites with >= 100 and < 1,000 breeder or feeder swine.
Non-commercial Production sites with < 100 breeder or feeder swine.
