Brucellosis Testing (Bleeding):

All cattle and domestic bison must be tested for brucellosis within 30 days prior to change of ownership or movement out of the DSA if they are:
  • Sexually intact and 12 months of age or older
  • Any age intended to be used for breeding purposes
  • Exceptions:
    • No test is required to take animals to an approved Montana livestock market that will test on arrival.
    • A test completed July 16 or after is acceptable for movement out of the DSA or change of ownership through February 15 the following year.

Identification and Disease Traceability:

All sexually intact cattle and domestic bison (regardless of age) leaving the DSA must be officially identified.

Official individual identification tags include:

  • Electronic Identification Device (EID) tags (also known as RFID tags);
  • Orange brucellosis (metal or RFID) vaccination tags on officially brucellosis vaccinated females;
  • Silver metal "Brite" tags (available to producers at no charge from the MDOL or USDA-APHIS office);
