Understanding Indiana's Animal Disease Traceability (ADT) Rule

Dec 08, 2014

Effective Jan. 1, 2015, Indiana's animal identification rules will change to comply with USDA's Animal Disease Traceability (ADT) program.

The changes reflect new federal requirements for identification and documentation for all major livestock species to improve national traceability in high-consequence disease incidents, such as bovine tuberculosis. Some of the dairy-specific requirements for ID actually took effect at the federal level in March of last year. Since then, the Indiana State Board of Animal Health (BOAH) staff has been working to rewrite state rules to align with USDA's.

The following guidelines describe what types of identification and documentation are considered official in Indiana, along with when they are required.

Tag Requirements

BOAH recognizes three forms of identification as official for cattle and bison. All are approved by USDA for interstate movements of livestock, and are accepted by all 50 states:

840 tags (15-digit number beginning with 840, may or may not be RFID)
NUES (brite) tags, available in steel or plastic ("steel clips")
Official USDA program tags (brucellosis)

To be considered official, all tags must bear the US shield. Old, out-dated tags are not acceptable, unless they were placed in the animal before March 11, 2015. After that date, all tags must comply with the new standards.

Video: Four Star Pork Industry Conf - Back to Basics: Fundamentals drive vaccine performance

At a time when disease pressure continues to challenge pork production systems across the United States, vaccination remains one of the most valuable and heavily debated tools available to veterinarians and producers.

Speaking at the 2025 Four Star Pork Industry Conference in Muncie, Indiana, Dr. Daniel Gascho, veterinarian at Four Star Veterinary Service, encouraged the industry to return to fundamentals in how vaccines are selected, handled and administered across sow farms, gilt development units and grow-finish operations.

Gascho acknowledged at the outset that vaccination can quickly become a technical and sometimes tedious topic. But he said that real-world execution, not complex immunology, is where most vaccine failures occur.
