Validation of a poll shot captive bolt as a single step method of euthanasia of cattle

Euthanasia should occur with minimal pain and distress for the animal and the person administering the procedure. The AVMA Guidelines for Euthanasia lists a frontal shot as the recommended anatomical location for both penetrating cap­tive bolt and gunshot euthanasia. However, in many situations access to the frontal site is not possible or may cause exces­sive distress to the animal. The objective of this study was to validate the effectiveness of a penetrating captive bolt when positioned behind the poll as a single step method for humane euthanasia of cattle.
