• Report on the scientific study in commercial slaughterhouses of turkeys with waterbath.

The technical study aimed at evaluating the prevalence and the inter-observer repeatability of the most valid and feasible animal-based indicators of the state of consciousness after waterbath stunning in turkeys before bleeding (tonic seizure, breathing, spontaneous blinking, and vocalisation) and during bleeding (wing flapping, breathing, spontaneous swallowing, and head shaking). In addition, correlations among them were computed to better understand their relationship and offer better insight on reliability of indicators. This was aimed at proposing a refined list of indicators that can be used in commercial slaughterhouses ensuring consistency of assessments. Moreover, the effectiveness of stunning according to different combinations of waterbath electrical key parameters (frequency and current) used in different commercial slaughterhouses was assessed in order to provide general recommendations.
