Apparatus for controlling the application of stun/kill voltage to an animal comprises means (5, 5') for applying a voltage to the animal; means (12) to sense the impedance of the animal in response to the application of an impedance sensing voltage by the voltage applying means (5, 5'), the impedance sensing voltage being less than the stun/kill voltage; means (1, 93) for predicting, from the sensed impedance, the impedance of the animal when the stun/kill voltage is applied; and means (1, 6) for controlling the application of stun/kill voltage. The stun/kill voltage is only applied if the predicted impedance is less than a predetermined impedance. In addition, apparatus for sensing the position of a pair of electrodes (5, 5') on an animal's body is presented. The apparatus comprises means (13) for sensing an electrical characteristic of the animal by measuring the electrical response of the animal to an electrical signal applied by the electrodes (5, 5'); and means (1, 3) to provide an indication of the position of the electrodes (5, 5') in accordance with the measured response. |
