Official ID for cattle and bison
With the speed of commerce today, it is more important than ever for livestock to be officially identified. Animals move within Minnesota and out of the state and country every day. In a disease event, we depend on your partnership! Official ID in your livestock and the records you keep help us improve our speed and efficiency while conducting animal traces.
Help us protect your livestock by applying official ID and keeping detailed records. You can use any of the approved official identification devices pictured below. Official ID may not be removed from an animal once it is applied.
