Abstract
An apparatus and method of installing livestock ear tags are provided. The apparatus includes handle members that control the insertion of a piercing needle that cuts an opening through an animal's ear. A slidable head assembly enables efficient manipulation of the piercing needle and reload of a new piercing needle for installing another tag. The piercing needle has attached to it a securing tab of the ear tag. The tab is stripped from the piercing needle after the needle clears the far side of the ear thereby securing the tag to the ear by placing the tab on the opposite side of the ear. The piercing needle is preferably disposable. The piercing needle has an integral tissue capturing cavity for capturing a slug of tissue from the animal's ear as the needle passes through the ear. The tissue sample can be used for subsequent animal health testing. The piercing needle is automatically captured by the tool after installation to prevent contamination of the tissue sample by release of the needle onto the ground. Another embodiment uses a tag with an integral needle, and the tag is installed in the same manner by the tool.
