Definitions

  • This invention relates to a system and a related method for processing poultry in a poultry slaughterhouse, which method includes a procedure of checking for dead individuals among the incoming live, but anaesthetized animals, or among incoming anaesthetized and killed animals, i.e., for screening for animals that are considered dead on arrival (DOA).
  • DOA dead on arrival
  • the system of the invention may additionally be combined with a system for visualisation of the results to a process operator, and the method of the invention may be combined with a process for performing a bleeding control of the killed animal.
  • the birds are usually transported to the slaughterhouse in cages containing a number of live animals. Upon arrival, the cages are typically unloaded and brought into the slaughterhouse, where the animals may be subjected to gas stunning while still in the cages, or they are removed from the cages and hung on the slaughter line for subsequent electrical stunning. After stunning, the birds are sent on for killing, which process is typically carried out on the bird, hanging on a conveyor, by vein section using rotating knifes.
  • Physiologic parameters as hock flexion stiffness and wing position are considered possible early DOA indicators when slaughtering laying hens or broilers. However, these characteristics can be difficult to detect when the birds are hanging very close together and partially overlapping each other, and moreover being conveyed at high speed.
  • EP819381 describes a method for processing a slaughtered animal in which method may include the step of determining, at the start of the slaughter line, the temperature and/or the stiffness of the animal for slaughtering and/or corneal reflex and/or a scan of the brain activity, so that it can be established whether the animal for slaughtering was still alive or was already dead on arrival at the slaughterhouse, followed by removal of the relevant animal from the slaughter-line and discharged from a discharging station.
  • W02004057969 describes a method for converting a fluctuating stream of poultry into a uniform stream of poultry, and mentions, that a check for dead on arrival (DOA) may be carried out by means of an infrared sensor which measures the temperature or presence of the bird. Removal of the dead bird may be carried out manually by the unloader, or it may be carried out mechanically.
  • DOA dead on arrival
  • EP2534953 describes a method for processing a slaughtered poultry, which method includes the step of establishing whether the poultry was alive or "dead on arrival" at the slaughterhouse and is based on detection of the temperature at the slaughtered poultry's breast, when said poultry is suspended by the legs on the slaughter line after stunning said poultry.
  • US2018360054 describes a system and method for detecting woody breast condition in broilers using image analysis of carcass features.
  • US9786060 discloses device for controlling the anesthetization of an animal to be slaughtered using image capturing and determination of movement of the animal
  • W02006029628 discloses an apparatus for checking bleeding from slaughter animals after they have been stuck by photographic colour analysis of pictures taken covering a region below the slaughter animal.
  • WO2017174768 discloses a system for recording and presenting performance data to an operator.
  • the system and related method of the present invention assist in implementing good product quality and compliance with food processing regulations, as well as for ensuring animal welfare.
  • thermographic (IR) camera that provides a thermographic image of the bird in question
  • RGB/colour standard camera
  • the colour camera additionally offers the advantage of correcting and interpreting the IR heat image more correctly, as it will be possible to differentiate other image features like feathering covering wings over the throat and appearing lumps of faecal and bedding material stuck to the breast which will impair correct understanding of the IR heat image if used alone.
  • thermal imaging together with standard RGB photographic imaging supplemented with the use of artificial intelligence and/or machine learning techniques on the resulting images, it is possible not only to identify the - often low - frequency of newly DOA outliers, but will also allow to train the system to better handle variations in appearance. Appearance of the bird may be affected, e.g., by seasonal and processing fluctuations, as well as variations in temperature, incl. the ambient temperature at the processing line and at the measuring area.
