The present invention discloses a livestock power generation system which generates electricity by using the habit of the livestock to produce rotational power to cut through electric current. The livestock power generation system is provided with equiangular radial levers to generate a moment of force by the marching of the livestock, which drives the livestock power generation system to rotate to generate electricity. In addition, by the assistance and management of an urging device and a stopping device, the operation of power generation by the livestock can be more stable.
