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.
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?
