 There are several systems that can be used to identify goats and sheep. The most common methods include air tagging, tattooing, and air notching. Each of these systems ensures that a unique number or symbol is given to the animals so that they can be identified. In this video, air tattooing will be demonstrated. The tattoo applicator is open and the numbers and or symbols are selected and placed in the tattoo instrument and tightly secured. The digits selected depend on the numbering system the farmer chooses. The digits in the tattoo instrument are sanitized by spring with alcohol. The air is cleaned with an alcohol swab on the inner side. Tattoo ink is rubbed on the inner side of the air. The side of the tattoo instrument with the digits is then squeezed on the inner side of the air and held there for a few seconds. The tattoo instrument is removed and the ink is rubbed into the applied area. Excess ink can be gently wiped away to ensure the digits are visible. The digits on this animal are T.J. 206.
