AB The voltages required to kill at least 90% of the birds by a 6-second passage through a water bath stunner were evaluated by the up and down method and the electrocardiogram to be as follows: layers 220 V/4-6 s, guinea fowl 250V/4-6 s, ducks 208V/3-4s, geese 376V/2-3s, adult turkeys (toms) 210V/2-4s, (hens) 360V/2-6s. Voltage differences between turkey males and females are related to impedance variations. High voltage required for geese might have resulted from reduced time of exposure. Thus 100 spent layers were culled in a waterbath stunner at 220V with "standard" (6-7s) or "prolonged" (10-12s) exposure time. In all "standard" and half the other hens the legs were wetted. Prolonged stunning time increased death rate by ca. 20% if the legs had been wetted. Prolongation of stunning exposure might thus help to raise killing efficiency but other stunning conditions must likewise be optimised.
