Physiological and behavioural responses in the hen (Gallus domesticus) to nociceptive stimulation

Abstract

1. Physiological and behavioural parameters were examined in the hen in response to a noxious and non-noxious stimulus. 2. Two distinct patterns emerged depending on the type of stimulus (noxious----crouching, non-noxious----wingflapping). 3. The responses seen in the hen to the two different types of stimuli appear to be similar to those occurring in mammals.
