RFID ear tags represent the modern standard for dairy cattle identification, replacing or supplementing traditional visual tags with electronic technology that enables automated, error-free identification.
Each RFID tag contains a microchip and antenna encased in durable plastic. When a reader emits radio waves, the tag responds with its unique identification number—typically following ISO 11784/11785 standards. This number links to the animal's complete record in herd management software.
For U.S. dairy operations, the USDA's Animal Disease Traceability (ADT) program increasingly requires official RFID tags (840 tags) for interstate movement. The 840 prefix indicates U.S. origin, followed by a unique 12-digit number assigned to one animal for life.
RFID technology has transformed dairy operations by enabling automated milk recording, individual feeding, sort gate decisions, and health monitoring. When a cow enters the parlor or passes a panel reader, her identity is instantly captured without human intervention, reducing labor costs and eliminating transcription errors.
Tag retention and readability are critical considerations. Modern tags feature improved button designs, two-piece construction, and tamper-evident features. Most manufacturers offer lifetime guarantees and replacement programs for lost tags.
