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: What Really Drives Meat Quality in Pork? - Dr. Yan Huang

In this episode of The Swine it Podcast Show Canada, Dr. Yan Huang from University of Arkansas explores how genetics, nutrition, and stress management shape pork quality. He explains how molecular pathways influence fat deposition, muscle growth, and meat flavor while balancing production efficiency. Listen now on all major platforms!

"The most important driver of pork quality. Feed plays a very important role in the meat quality."

Meet the guest: Dr. Yan Huang / yan-huang-77829421 is an Associate Professor in Nutritional Skeletal Muscle Biology at the University of Arkansas. With academic experience across China, South Korea, and the United States, his work focuses on the genetic and molecular regulation of muscle growth and fat deposition in swine. His research connects genetics, nutrition, and pork quality to improve production efficiency and consumer satisfaction.
