Résumé
The aim was to study the influence of the emotional reactivity on behavioural and cardiac responses in birds during emotional situations. Behavioural and heart rate variability measurements were studied in quail selected on either a long (LTI) or a short (STI) tonic immobility duration. STI and LTI quail exhibit low and high emotional reactivity. In 2 emotional situations, sympathetic activity increased in all lines, however, parasympathetic activity decreased in STI and LTI during an object presentation while it increased in STI after an acoustic stimulation. Emotional reactivity and the test situation then influence autonomic and behavioural responses during emotional situation. Finally, the study of the emotional responses could help the evaluation of animal welfare in rearing conditions.
