Low atmospheric pressure stunning (LAPS) has been suggested for use in poultry under 4 kg in the abattoir as a more humane alternative to
carbon dioxide
(CO
2
). However, there are currently no studies offering a direct comparison of the aversion between methods. Here, we trained adult female broiler breeders to relinquish a food reward by moving to another area of the gas chamber in response to aversive stimuli. They were then stunned and subsequently killed using single exposure to either CO
2
, N
2
, LAPS or medical air as a control. Birds exposed to CO
2
relinquished the food reward the quickest and exhibited gasping and headshaking more than the other groups. LAPS resulted in the quickest time to loss of posture (LOP) and birds in the N
2
group took the longest. Birds exposed to N
2
displayed the longest duration of
ataxia
of any group; however, they did not show any wing-flapping prior to LOP, unlike the LAPS and CO
2
. Collectively these data demonstrate that both LAPS and N
2
are less aversive to poultry than CO
2
and may offer a significant welfare refinement for poultry killed for meat production.
