Bison and Cattle

General Information

The references to "bison and cattle" in the language below include all bovine (genus Bos) animals, bovine-like animals (genus Bison-also commonly referred to as American buffalo or bison), and any cross of these animals.

Coming into Michigan from Another State (Import)

  1. Bison and cattle must have an official interstate certificate of veterinary inspection (CVI) filled out by a United States Department of Agriculture (USDA) accredited veterinarian.
    1. Please note that Michigan does not issue entry permits for bison and cattle to be imported. Therefore, when completing the interstate certificate of veterinary inspection, a permit number does not need to be included. 
    2. When bison or cattle are imported from a herd under an official Herd Health Maintenance Plan, the following statement must appear on the interstate CVI.

"This herd is inspected as part of a regular health maintenance program and all animals listed on this CVI have been examined within the last 30 days."

  1. When bison and cattle without official identification are moved directly to an approved tagging site, the national premises identification number (PIN) of the herd's origin and the following statement must appear on the interstate CVI:

"This herd will be officially identified at the approved tagging site."

Exception:  Bison and cattle going directly to slaughter or through one livestock auction market and then to slaughter may be accompanied by an owner shipper statement (OSS) instead of an interstate CVI. 

  1. Unless moving directly to an approved tagging site, bison and cattle must have an official identification (ID) ear tag regardless of age, breed, or sex. Official ID ear tag numbers must be recorded on the interstate CVI.

Official Identification Options:

  1. Metal NUES ear tag depicting the U.S. Route Shield.*
  2. Animal Identification Number (AIN) ear tag:  may be a visual tag or a Radio Frequency Identification (RFID) tag.*
    1. AIN ear tags applied to animals of U.S. origin must depict the U.S. Route Shield.
    2. AIN ear tags applied to animals of U.S. origin on or after March 11, 2015 must have a 15-digit number that begins with 840.

*All bison and cattle moved directly to a Michigan livestock auction market must have official RFID ear tags to be consigned for sale. Animals can have official RFID applied upon arrival, at the owner's expense, if:

  1. the Michigan livestock auction market is an approved tagging site, and
  2. the person responsible for the animals provides the approved tagging site with the national premises identification number (PIN) of the animals' origin.

Exception:  Bison and cattle moving directly to slaughter may enter Michigan with USDA approved back tags in place of official ID.

  1. There are no bovine tuberculosis or brucellosis testing requirements or brucellosis vaccination requirements for bison and cattle being imported into Michigan from states or areas officially designated as tuberculosis accredited free and brucellosis class free by USDA.  If you are interested in bringing bison or cattle into Michigan from states or areas that do not have these designations, please contact MDARD at 800-292-3939 prior to entry.
