The cats have not been found responsible for a livestock death since the predator re-emerged in the state in 1991.
Nebraska Game and Parks Commission officials confirmed that a mountain lion was responsible for the death of a calf last month near Brewster. The rancher reported the kill on April 2 after finding the carcass had been dragged about 60 yards and fed upon.
Game and Parks officials were able to use animal droppings found nearby to confirm that a mountain lion was responsible for the death. The rancher was granted a 30-day hunting license to kill the mountain lion if it returns to his property.
According to Game and Parks officials, livestock losses are more common in western states with larger lion populations.
