State agricultural officials are allowed to continue regularing deer and elk farms.
A legislative committee voted unanimously Thursday to the action as part of the state's battle against Chronic Wasting Disease.
The Department of Agriculture, Trade and Consumer Protection created emergency rules in April and May regulating the farms.
But the Joint Committee on Administrative Rules was required to approve extending the department's authority to keep those rules in effect through June 1.
The department is working on permanent rules that would need legislative approval to go into effect possibly next year.
The Department of Natural Resources announced in February that three bucks shot in the Mount Horeb area last November had the disease. It was the first time CWD has been found east of the Mississippi River.
Since then, nearly 1,500 deer have been killed to wipe out the deer herd in the infected area.
