Colorado wants more ID for Yellowstone-area cattle
Cheyenne, Wyo. – Concern about brucellosis is prompting Colorado to impose tougher identification requirements for cattle that have spent time in the Yellowstone region in Wyoming, Idaho and Montana.
Nebraska is working on similar requirements. Livestock officials tell The Associated Press they wouldn't be surprised if more states followed suit to keep out brucellosis.
Brucellosis spreads to cattle from wildlife and can cause cows to abort their calves. The disease has been persistent in the Yellowstone region, appearing in cattle in all three states in recent years.
Colorado's new rule goes into effect Sept. 1 and will require all sexually intact female cattle that have spent time near Yellowstone to carry a Colorado-approved ear tag.
Livestock officials in the three states say cattle ranchers are unlikely to have difficulty following the requirement.
