The equine faeces collection system includes an excrement collection device (2) in tube form with a faeces outlet (70) connected to the collection deposit intake (7) and an intake mouth (13) adapted to face the animals anal area to lead the excrement through to the deposit. The collection device (2) has a first collection area (8) with an outlet mouth connected (70) to the collection deposit intake (7), and a second collection area (11) with an intake mouth (13) which is coupled to the first area (8) to move from a rest position to a collection position in which the intake mouth (13) is facing the animals anal area, in which collection position this intake mouth is located over the outlet mouth so that the excrement runs through to the faeces deposit by gravity. In addition, a turbine (9) moved by an electrical motor (10) could be mounted inside the first collection area (8) to help drag the faeces through to the deposit (7).
