This is the gory moment Chinese zookeepers push a live donkey into the jaws of three hungry tigers.The terrified animal can be seen clinging on for dear life as workers in raincoats push it down a ramp and off a steep ledge into a tiger compound.After landing hopelessly in the water, the donkey is soon attacked by two nearby tigers. The ferocious predators - believed to be kept at Changzhou zoo in eastern China - work together to deprive their prey of any hope of escape. With the prey obviously killed, the camera cuts to four of the lions relaxing before showing the bloodied donkey being hauled onto land for consumption. According to the video, the tigers killed the donkey in just half an hour.
