Facilities for and method of separating and sorting livestock

An assembly comprising a single passageway for livestock, the passageway being delimited by side delimitations, for passage of the livestock from a first space to a second space, the assembly comprising:

• a gate system mounted in the passageway, the gate system having at least one self-closing gate leaf which is movable between a closed position and one or more open positions including a pass position wherein passage from the first space to the second space is possible for an animal from the livestock, wherein the gate leaf is arranged for movement to one of the open positions by the exertion of pressure by an animal from the livestock passing through the passageway to the second space;
• a stop device disposed on a side of the gate leaf facing the second space, wherein the stop device can be placed in a rest position, or an active position in a swivel path of the gate leaf for preventing the gate leaf from moving into the pass position;
• wherein, in the rest position, the stop is positioned at a distance from the gate leaf so that the gate leaf is moveable from a closed position to an open position, and in the active position, the stop abuts the gate leaf;
• and
• a device for moving the stop device between a number of positions which are positioned within a path of movement of the gate leaf and are positioned at a distance from one another along the path of movement.

An assembly comprising a passageway for livestock, the passageway being delimited by side delimitations, for passage of the livestock from a first space to a second space, the assembly comprising:

• a blocking device;
• a gate system mounted in the passageway, the gate system having at least one self-closing gate leaf which is freely movable, when the blocking device is deactivated, between a closed position and one or more open positions including a pass position wherein passage from the first space to the second space is possible for an animal from the livestock, wherein the gate leaf is arranged for movement to one of the open positions by the exertion of pressure by an animal from the livestock passing through the passageway to the second space, and wherein the gate leaf is blocked from opening when the blocking device is activated;
• a counting device for counting the number of animals which have passed through the passageway to the second space, wherein the counting device is configured for issuing a count signal as a function of a movement, observed by a gate sensor, of the gate leaf;
• wherein the blocking device comprises a stop for blocking abutment against a surface of the gate leaf which faces the second space;
• and
• a device for moving the stop between a number of positions which are positioned within a path of movement of the gate leaf and are positioned at a distance from one another along the path of movement.
