On our farm we use eartags to give each animal an unique identifier that allows us to keep important health records for each animal. Here are a few pictures that show the tags up close.
The tags are applied in a similar fashion to earrings through a soft portion of the ear. Each tag is self contained and is clean and sterile.
The information of the tags includes our farm brand (starting at the very top of the biggest tag), next is the unique “840″ number assigned to only this animal in the United States, followed by the unique number for our farm, in this case 2129. The small white tag has the same numbers and also id an EID tag that contains an RFID information. We currently do not utilize the RFID tag outside of visual use however are we will be implementing the electronic reading in the future to help with efficiency and to eliminate human error.
