Abstract: Described is a water distribution system (1) with a continuous main line (10). Drinking cups (20) are placed on drinking segments (11) of the main line (10). Between the drinking segments (11) the main line (10) has intermediate segments (13), which are situated at a higher level than the drinking segments (11). The drinking cups are situated at a level suitable for drinking, and the intermediate segments are situated at a level suitable for allowing the birds to pass through unhindered underneath them. The complete line system can be cleaned by means of flushing, and has no dead-end branches. Top edges (22) of the drinking cups (20) are advantageously fixed to vertically directed line segments (13). The water distribution system (1) is modular.

Abstract: A feeding installation has at least two feed containers from which feeds of different composition are conveyed by means of a feed conveying device to feeding devices. The feeding devices are connected to the feed conveying device by way of valves. The valves have two or more slide elements which are slidable relative to each other and are provided with an opening, for allowing or blocking the passage of feed.

Abstract: A feeding device for birds, in particular for breeders with a limited, predetermined daily ration of feed. The device has a dish-shaped pan with a bottom and upright peripheral wall, a drop tube with an open upper end which can be coupled to a feed supply system. The drop tube also has a lower end which is situated above the dish-shaped pan. The sum of the volume of the dish-shaped pan and the feed volume of the drop tube is at most equal to the volume of the sum of the daily rations of feed for the birds feeding at the device at the same time. A filling element may be provided in the drop tube, spaced from the inner wall of the drop tube.

Abstract: A feeding device for poultry has a dish-shaped pan, above which a feed drop tube is centrally arranged. The upper end of the feed drop tube can be brought in open connection with a feed supply tube of a feed supply system. Between the feed drop tube and the pan a plurality of support arms is present which are connected to a rim of the pan by means of a snap connection with two transverse arms extending along the rim of the pan and having hook lugs and a supporting lip. The feeding device is connected to the feed supply tube by two yoke parts which, together, enclose the feed supply tube, the first yoke part having two yoke arms with hook parts directed towards each other for enclosing the second yoke part.

Abstract: A poultry feeding device comprises an essentially dish-shaped pan, the bottom of which is provided with an upright part. A drop tube for the supply of feed can be moved over a limited, variable distance relative to the bottom of the pan to form a first feed supply opening of variable size. The drop tube has one or more second feed supply openings. In the bottom position of the drop tube the first feed supply opening is closed and the second feed supply opening(s) are opened, and in the top position of the drop tube this is reversed. The upright part of the bottom of the pan extends in the drop tube, and in the bottom position of the drop tube the top side of the upright part reaches to the second feed supply opening(s) and at that point shuts off the drop tube.
