Authorities say a barn fire in northern New York killed 120 cows and 40 calves.

The fire broke out just before midnight Monday at the Scott Markham farm in Constableville, about 70 miles northeast of Syracuse.

Lewis County Fire Coordinator James Martin says the building and its contents — including the livestock, milking equipment, two tractors and a generator — are a total loss.

The cause of the fire remains under investigation. It apparently started in the front of the 24-year-old barn, possibly in the area of the milkhouse.

There was insurance on the barn.
