The South Dakota Animal Industry Board has voted to repeal a nearly 40-year-old rule requiring quarantine for baby calves entering the state without their mothers.
The ruled was proposed at the board's annual meeting Tuesday by State Veterinarian Dustin Oedekoven.
The state previously required 60 days of separation for young calves who came to South Dakota without their mothers.
The board also repealed a rule from April 2013 that required cows from Idaho that were older than 18 months be tested for brucellosis before coming to South Dakota.
Oedekoven briefed the board on the status of Porcine Epidemic Diarrhea in the state. There are 32 infected herds in the state.
Federal dollars are now available for newly infected herds to manage the virus and research vaccines.
