MADISON, Wis. (AP) – The biggest impact Wisconsin farmers could experience from the government shutdown could be delays in federal payments that typically arrive in October.  That’s according to Wisconsin Agriculture Secretary Ben Brancel, who spoke Tuesday at the World Dairy Expo in Madison.  Brancel says the delays could include any checks dairy farmers might be owed by the federal milk income loss program, which pays farmers when milk prices fall below a certain point.  Those checks could be the last ones farmers receive from the program, which ended Sept. 30 with the expiration of a farm bill extension. Congress is still working on a new farm bill.
