Definitions

  • the invention relates to the stunning of an animal for slaughtering, for instance a pig.
  • the invention relates to a method for stunning an animal for slaughter, e.g. a pig, comprising the steps of:
  • the invention relates to a device for stunning an animal for slaughter, for instance a pig, for application of the method specified herein above, said device comprising;
  • At least one second electrode to be pressed against the body of the animal, said electrical supply means being also connected to said at least one second electrode for causing a second current pulse to flow via said at least one second electrode through the body of the animal to cause cardiac arrest.
  • the invention has for its object to provide a method and associated device with which an animal for slaughter can be rapidly stunned using simple means, wherein needless suffering is prevented and the quality of the meat is not adversely affected.
  • achieving effective stunning it is important that the animal remains substantially still after the treatment.
  • This is important in respect of the subsequent treatment which, in accordance with a normal procedure, consists of arranging a chain around one of the hind legs, suspending from the conveyor and subsequently piercing the carotid artery to kill the animal.
  • the invention has for its object to provide a method and associated device with which the stunning of the animal for slaughter can take place during the transporting of the animal by means of conveying means, such as a restrainer, without the necessity of stopping the transport during the stunning operation.
  • conveying means such as a restrainer
  • This method can for instance be performed such that the second current pulse is caused to flow through the neck- and/or head-region and the heart region of the animal.
  • the first and the second current pulse can have a duration of a maximum of 10 secs. and preferably a duration of 1-2 secs.
  • the total duration of the first and the second current pulse together is preferably 2.5-3 secs.
  • the effective voltage of the first current pulse and of the second current pulse is preferably a maximum of 1000 V.
  • the first and second current pulse can each consist of an alternating current with a frequency of a maximum of 1000 Hz.
  • a method in which these frequencies are the same as the mains frequency has the advantage of easy availability.
  • EP-A-0 019 332 an apparatus is known in which electrodes adapted to engage the head of an animal to be stunned are movable along a restrainer in a reciprocating fashion. No electrodes engaging the breast or other part of the body of an animal is used.
  • EP-A-0 021 548 also relates to such a device in which the head electrode said is movable together with the animal carried by the restrainer. No breast electrode is used.
  • FR-A-2 390 903 relates to a device in which, the electrodes are carried by hingible arms, so that they can more or less follow the movement of an animal during the stunning operation.
  • the method according to the invention is implemented in material sense with a device for stunning an animal for slaughter, for instance a pig, with application of the method as described above, said device being characterized in that: the first and second electrodes are movable together with said conveying means.
  • the apparatus known from NZ-A-201 402 for stunning an animal and causing cardiac arrest uses a current flowing through electrodes arranged in the head and the breast region of an animal, respectively. These electrodes are not movable together with a conveyor, but are rather positioned in a fixed stationary position.
  • the device according to the invention is characterized in a variant by means for lowering the transition resistance between the electrodes and the animal. This ensures that at a determined voltage a desired strength of current can be obtained.
  • the device according to the invention can be characterized particularly for this purpose by pressing means for pressing the electrodes against the animal with chosen forces.
  • the device can have the feature that the third electrode is adapted to be pressed against the thorax region of the animal such that the second current pulse is caused to flow to at least a significant degree through the heart region.
  • the device characterized in that the at least one first electrode is carried by a first carriage which can be moved reciprocally along said conveyor such that said at least one first electrode can make contact with an animal for slaughter carried by said conveyor during the first current pulse having a maximum duration of 10 secs.
  • the device may be characterized in that the second electrode is carried by a second carriage which can be moved reciprocally along said conveyour such that said second electrode can make contact with an animal for slaughter carried by said conveyor during the second current pulse having a maximum duration of 10 secs.
  • the device is characterized in that said first and second carriages are coupled for simultaneous reciprocating movement along said conveyor.
  • the device is characterized in that said first carriage is also said second carriage.
  • the device is characterized in that said at least one second electrode forms part of the outer surface of said conveyor. It can be practical to use an external electrical contact connected with the power supply for supplying the second current pulse in a way such that said second electrode is connected with the power supply only during a predetermined time interval. The second current pulse is fed to the second electrode only during that interval.
  • FIG. 1 shows a perspective view of a pig lying on a restrainer, wherein a device according to the invention is shown highly schematically in operating situation;
  • FIG. 2 shows a partly broken away perspective view of a practical embodiment of the device.
  • a pig 2 Lying on a conveyor belt 1 , a so-called restrainer, is a pig 2 which is to be stunned and slaughtered.
  • a number of electrodes in the embodiment drawn two head electrodes 3 , 4 and a breast electrode 5 , which are connected to an electrical mains supply device 6 for successively causing to flow a current pulse through the head of the pig 2 via the electrodes 3 and 4 and then causing a second current pulse to flow through the heart region of the animal via the electrode 5 and at least one of both electrodes 3 , 4 .
  • the reference numeral 7 designates a mains transformer which provides a power supply source 8 with the correct voltage and current.
  • the electrodes 3 and 4 receive current via a first switch 9 , while passage of current via the third electrode 5 is controlled by a second switch 10 . These switches are controlled by a control unit 11 which ensures that a first current pulse is caused to flow through electrodes 3 , 4 followed by a second current pulse via respectively the head electrodes 3 and/or 4 and the breast electrode 5 .
  • the conveyor 1 comprises a chain 12 which is driven by non-drawn means and bears blocks 14 each provided with a central longitudinal recess 13 .
  • the longitudinal recess 13 has a form such that the breast bone of pig 2 can be accommodated therein.
  • This conveyor has a construction such that the pig remains lying docilely thereon in a fixed position.
  • a carriage 19 is displacable by means of wheels 18 in lengthwise direction with conveyor 1 .
  • This carriage 19 can be driven by a cylinder 20 which is energized by non-drawn means for reciprocating displacement of carriage 19 . Because the carriage 19 is driven in the transporting direction 21 at the same speed as conveyor 1 the electrodes 3 , 4 , 5 , after having been placed in the desired position, can move along with the pig 2 for a period of time.
  • the electrodes 3 , 4 are carried by a pivot arm 22 which is pivotable by means of cylinders 23 , the driving whereof is likewise not drawn.
  • the electrodes 3 , 4 can be arranged with some force against the head of pig 2 .
  • Electrode 5 is carried by a plate 24 which is movable toward and away from pig 2 by means of a cylinder 25 . This latter engages onto an arm 26 which, together with an arm 27 parallel thereto, supports the plate 24 .
  • the electrode 5 is through plate 24 and arms 26 , 27 supported by a second carriage 30 provided with a pin 31 cooperating with a driving arm 32 connected with carriage 19 for reasons of mechanical stiffness, the arm 32 is supported by a stiffening arm 33 extending between the frame 39 and the lower end of arm 32 , which has a fork-shaped end 34 cooperating with pin 31 .
  • carriages 19 and 30 are driven simultaneously by cylinder 20 with the same speed as the conveyor 1 speed.
  • the electrodes 3 , 4 , 5 can be pressed with a sufficiently great pressure against the pig 2 , whereby the transition resistance between the electrodes and the pig remains limited and a relatively high current can be realized at a relatively low voltage.
