  • Inlets
  • Heaters
  • Troubleshooting

Workshop material can be tailored for wean-finish, sow, and/or farrow-finish swine operations, or for poultry and cattle systems.

The Four-State Ventilation Trailer is available to practice ventilation management and troubleshooting. The trailer includes a control system, various inlet types, and multiple fans.

The trailer and ventilation workshops bring education to your area, while protecting biosecurity.

Biosecure Entry Education Trailer

The BEET and associated educational programs are adaptable for training on the various formats of biosecure entry to livestock and poultry facilities. The trailer brings education to your area, while protecting biosecurity.

Owners and managers need to decide which practices fit their management needs.

Employees need training to know how to properly carry out Danish entry plans.

Managers responsible for making biosecurity plans can use the trailer to practice their plans for entry into poultry barns based on Danish entry concepts. Employees expected to carry out biosecurity plans can use the trailer to practice company plans and deal with unusual situations that may come up.

The BEET trailer is mobile and available for training purposes on-site, statewide.

For more information, contact Abby Schuft ([email protected]).

Initial funding for the trailer came from the Rapid Agricultural Response program.
