Nitrogen Foam Delivery System

A depopulation solution for large scale disease outbreaks

How do you humanely depopulate a large number of animals efficiently, whilst reducing stress for those who work on the farm?

The NFDS minimises pain and stress as it eliminates hypoxia, mitigates the need for excessive handling, and guarantees the absence of tracheal occlusion.

How does the Livetec NFDS work?

The problem

Although hypoxia, which occurs when the blood doesn’t carry enough oxygen to the tissues, is deemed an acceptable depletion and depopulation method for pigs and poultry worldwide, it is not used.

Using inert gases like nitrogen and argon in depopulation can be achieved.

But, why has it not been used for whole-house gassing? The reason is, how do you seal a house or shed and adequately eliminate the oxygen?

The solution

Foam generators:

  • High standards of efficiency
  • Generating up to 50m3 (1765 CU ft) of high expansion nitrogen foam per minute

Process:

  • Animals loaded into relevant holding pen, trailer or building
  • Nitrogen is delivered as a gas-filled foam
  • The foam envelopes the animals eliminating oxygen
  • Animals are stunned within 1 minute, leading to anoxia
  • Foam blown away
  • The animals can be collected where they lay
  • The shed does not have to be sealed.

The NFDS is made using modular units, which hold five key components.
