Description

Title: Housing arrangement for pigs

The invention relates to a housing arrangement for group housing of pigs, comprising a living area for pigs provided with identification means and at least one feeding installation for feed provided with an identification system for pigs. Such a housing arrangement is known from practice. The known housing arrangement comprises at least one feeding installation which can be approached freely by the pigs. The feeding installation comprises a feeding trough, which is provided with a transceiver of an RFID system (Radio Frequency Identification system). The transceiver is arranged for recognizing responders carried by the pigs, in which, for each pig, a unique identification code is stored. The transceiver is further connected with a central processor, in which data with respect to the individual pigs are stored. In addition to the identification code of a pig, these data also comprise inter alia data about the feed supply to the pig, the health condition of the pig and the like.

When a pig arrives at the feeding trough, the identification code of the pig is recognized by the identification system. The central processor then determines on the basis of the data associated with the detected identification code whether the respective pig has a right to feed and, if so, to what amount. If the pig has a right to feed, the central processor controls a feed metering device of the feeding installation, which drops the desired amount of feed into the feeding trough.

When the pig has finished the feed and notices that the feeding trough is no longer filled, it leaves the feeding trough, so that then the feeding trough is free for another pig.

A problem that occurs with the known pig housing is that, for instance, a dominant pig, which has no right to feed, tries to chase away a pig which is eating. This can lead to fights and injury of pigs, while then, in addition, it is no longer guaranteed that all pigs get the right amount of (concentrate) feed. Further, it is difficult in the known housing to locate individual pigs and separate them, if desired, for an individual treatment, such as for instance the administration of medicines.

The invention contemplates providing an improved housing arrangement for group housing of pigs, where the above-mentioned problems do not occur or occur to a lesser degree. More generally, the invention contemplates providing a housing arrangement with which pigs can be kept in an efficient, βafe and well controllable manner, and can also be individually located and fed.

A housing arrangement for group housing of pigs of the above-mentioned type is, according to the invention, characterized by a number of individually identifiable feeding cubicles for pigs located in the living area, which cubicles are each provided with an individual transceiver for an RFID system for identifying a pig present in a feeding cubicle, while the at least one feeding installation comprises a feeding trough for each feeding cubicle and a number of feed metering devices cooperating with the cubicles, which are individually controllable per cubicle. It is noted that DE 201 03954 Ul describes a housing arrangement for group housing of pigs, which comprises a number of feeding cubicles. The feeding cubicles are of the walk-through type and are located in a waiting area separated from a living area. The waiting area has one or more access doors, which are operated by an optical recognition device for pigs. When a pig arrives at the access door to the waiting area and is found, after recognition, to have a right to feed, the access door is opened, provided that at least one of the feeding cubicles in the waiting area is free. The pig can then enter the waiting area. The feeding cubicles themselves also have lockable access doors and one of those access doors of the feeding cubicles is also automatically opened after opening of the access doors of the waiting area. The pig can then enter that feeding cubicle and can eat there. When the supplied feed is finished, the pig can leave the feeding cubicle at the end opposite the access door and reach the living area again through a bypass corridor. A housing arrangement with feeding cubicles provided with an RFID system is not described in DE 201 03954.

Further, from EP 0610 171 A2, a feeder cage for pigs is known. This known feeder cage has a feeding trough, which can be released or made inaccessible depending on the identity of a pig detected by an identification device. However, this known feeder cage is of the walk-through type with an entrance door and an exit door positioned opposite the entrance door. A housing arrangement with feeding cubicles is not described in EP 0 610 171 A2.

In the following, the invention will be described in more detail with reference to the appended drawing, in which: Fig. 1 schematically shows, in cross section, an example of a pig housing with a housing arrangement according to the invention; and

Fig. 2 shows an example of a block diagram of the electronic part of a housing arrangement according to the invention; and

Fig. 3 shows an example of a slightly more detailed block diagram of a housing arrangement according to the invention.

Fig. 1 schematically shows, in cross section, an example of a pig housing for group housing. A barn building 1 has an interior space 2 arranged for group housing of pigs, such as for instance sows. In the example shown, there are two rows 3, 4 of feeding cubicles 5 in the interior space. The number of feeding cubicles is preferably at least equal to the number of pigs. The feeding cubicles have an entrance on the side facing away from the interspace 7, which also forms the exit. The rows of feeding cubicles are arranged opposite one another with some interspace 7. In this example, the feeding installation comprises a feeding trough 8 located in the interspace in front of each cubicle and a number of feed metering devices 14 individually controllable per cubicle, which are schematically shown. On the sides of the cubicle rows facing away from the interspace 7 and the feeding troughs 8, there is a roaming area 9, 10, where the pigs can walk around freely on a grid floor or on straw. In this example, the roaming areas are limited by end gates 11, 12.

The cubicles in the example described below are of the self-catching type known per se. Such cubicles close automatically when a pig enters the cubicle, if at least the locking device of the cubicle has been cocked first. However, the invention is also usable with feeding cubicles which are not of the self-catching type. However, the cubicles are preferably provided with an optionally remotely lockable entrance gate in order to separate a pig if desired and/or to be able to prevent pushing away by another pig.

As soon as a portion of concentrate is dropped into the feeding troughs, the pigs will enter the cubicles. The cubicles are then first cocked, as far as necessary, and close themselves behind the pigs. If the pigs do not get any other food, they will enter the cubicles directly when the feed is dropped into the feeding troughs. Thus, each pig can eat in peace and quiet without being chased away by another pig. After some time, the feeding cubicles can be unlocked centrally.

However, it is also possible to unlock the cubicles individually, or to leave them locked for a longer period. For unlocking, generally various methods are available. This may, for instance, be done electrically wirelessly or through cables and/or by means of manual operation. Each cubicle is automatically individually identifiable by software and/or hardware and is provided with an RFID transceiver of an RFID system for recognizing the identification code of a pig present in the cubicle. To this end, in a manner known per se, the pigs can be provided with identification means in the form of RFID responders in which an identification code unique to each pig is stored. The responders may be one of the known types of responders, for instance ear responders, collar responders, implanted chips or the like.

Fig. 2 schematically shows a series of self-catching cubicles 20-25, one of which is drawn larger than the others. The cubicles are each provided with an RFID transceiver 26. The cubicles are further provided with connections 27 for electrically locking/unlocking the cubicles and with control connections 28 for controlling one or more feed metering devices. Further, all cubicles are connected with a central processor 30 comprising a database 30a in which data of the individual sows, such as for instance the health condition of the sows, the amount of concentrate to be supplied, etc., are stored.

As soon as a pig is present in the cubicle and starts to eat the first portion of feed, the identification code of the pig is recognized by the RFID system. The identification code is, together with a hardware-mediated or software-mediated identification of the cubicle in which the pig is present, transmitted to the processor 30. To this end, a cubicle may, for instance, be provided with a number. By comparison of the identification code of the pig with the identification codes stored in the database, then the feed need of the respective pig can be determined, for instance whether the respective pig needs extra and/or special feed and, if so, how much. Then the processor transmits a control signal through the control connection 28 of the respective cubicle to the feed metering device of the cubicle in which the pig is present. In this manner, each sow can be fed individually.

It is possible that some sows require special attention, for instance on the basis of their health condition. In order to locate such sows, the cubicles may be provided with one or more indicators 31, for instance a lamp or a red LED or the like. The indicator is excited as soon as a pig of which it is indicated in the database that it requires special attention is detected in a particular cubicle. It is possible that certain pigs which need extra attention or care need to be kept longer in the cubicle. In that case, that cubicle can remain locked longer while the other cubicles are centrally unlocked. This may be brought about electronically or software-wise, but also manually. In the latter case, for instance, near the respective cubicle or remotely, a switch can be turned which switches off the central unlocking for that cubicle or, for instance, an extra lock can be used, which either mechanically prevents the electronic unlocking or brings about an extra locking, which is not controlled by the central unlocking device. It is further possible to use a display with input facility per cubicle or series of cubicles, which display displays the individual sow data of the sows present in those cubicles, as a replacement of the sow card. Fig. 2 schematically shows, by way of example, such a display 32 with cubicle 20. It is noted that, after the foregoing, various modifications are readily apparent to a skilled person. Thus, it is, for instance, possible to provide each cubicle or a group of cubicles with an individual processor, which has its own database and/or is coupled with a central database.

An example of such a configuration is schematically shown in Fig. 3. Fig. 3 shows, in a block diagram, a number of feeding cubicles Vl... Vn. The feeding cubicles shown are, in this example, each provided with a local processor PVl...PVn. The local processors are connected with a central processor 30, which has a central database 30a. The local processors can contain a local database DB 1...DBn. Further, the local processors are provided with a control connection 28 for controlling one or more feed metering devices 28a, and with a connection 27 for controlling a locking and/or unlocking device 27a. The local processors are further connected with an RFID transceiver 26. Fig. 3 furthers shows indication devices 31, which are also connected with the local processors, and a display 32, which is connected with local processors P Vl... PVn of the group of feeding cubicles Vl...Vn. It is further noted that, if desired, different types of indicators can be used for different situations. With respect to the feed metering devices, it is noted that it is possible that the use of multiple types of feed is desirable. In that case, for instance, a first feed metering device for a first type of feed, a second metering device for a second type of feed, etc. could be used. In addition, it is possible to use common feed metering devices for adjacent feeding cubicles. This could, for instance, be a feed metering device moving along two or more feeding cubicles, which successively provides the feeding troughs of the respective feeding cubicles with feed by successive control of the associated connections 28. It is also possible to use a combined feed metering device for two adjacent feeding cubicles with, for each feeding trough, a separate nozzle and an associated metering element, such as a metering screw, controlled by the respective control connections 28. Instead of separate nozzles, a single nozzle which is pivotable to and fro could be used.

Further, the invention is also usable with a housing arrangement with feeding cubicles which are open on the entrance side, or which are provided with an access gate, which normally remains open, but which can be closed if desired via a remote control or locally manually. The RFID system may be arranged such that a pig is only recognized at the feeding trough. However, it is also possible to arrange the RFID system such that a pig is already recognized upon entering a feeding cubicle, optionally in combination with a further recognition at the feeding trough. Such modifications are understood to fall within the framework of the invention.
