Stress in poultry can produce many undesirable effects on bird health and production performance. The objective of this study was to develop and evaluate a potential measure to assess stress through analysis of brain activity using electroencephalography (EEG). In two experiments, White Pekin ducks were implanted with EEG transmitters and treated with potential stressors in a chamber or in their pens. Electrocardiograms and blood corticosterone levels were collected as standard measures of stress. EEG analysis showed an increase in the relative delta frequency and a decrease in the relative alpha frequency during the treatment period for shock (P < 0.05). EEG analysis of the second experiment showed no differences between time periods for all frequencies for all treatments. Based on these results, EEG is currently not a viable technique for the measurement of acute stress in commercial poultry.
