Other aspects of the invention and various advantages and characteristics of the Rabbit slaughtering apparatus will be apparent from the consideration of the following detailed description. A small bird can be slaughtered by manual neck dislocation. The novel mechanical cervical dislocation device resulted in consistent anatomical damage to the birds (eg high dislocation of the neck and severing of the spinal cord) compared to the manual method, despite both having 100% success rate, while the modified Rabbit Zinger™ was difficult to operate and resulted in varied anatomical damage. 1.Four mechanical poultry killing devices; modified Armadillo® (MARM), modified Rabbit ZingerTM (MZIN), modified pliers (MPLI) and a novel mechanical cervical dislocation gloved device (NMCD), were assessed for their killing potential in chicken the cadavers of euthanised, of four bird type and age combinations: layer/adult, layer/pullet, broiler/slaughter-age, broiler/chick. Privacy Policy We evaluated blunt force trauma (BFT), a mechanical cervical dislocation device (MCD), and a non-penetrating captive bolt device (NPCB) for euthanasia of pre-weaned kits, growers, and adult rabbits. Basically, you lay the rabbit down on the ground, and put a bar across the back of the neck stepping down on either end of the bar, with a swift motion, you pull up on the hind legs, dislocating (breaking) the neck of the rabbit. 1 is a perspective view of the rabbit slaughtering device constructed in accordance with the present invention. We use it as a towel holder. We evaluated blunt force trauma (BFT), a mechanical cervical dislocation device (MCD), and a non-penetrating captive bolt device (NPCB) for euthanasia of pre-weaned kits, growers, and adult rabbits. A rabbit and poultry cervical vertebral dislocation device more simply put “neck breaker” comprises a cylindrical rod attached to an L-shaped base frame and mounting flange. A still further object of the invention is to provide a rigid angled stop at the rear of the inverted wedge with the opposing rigid structure being at a sharp angle, this with two opposing rigid structures comprising the inverted wedge. This invention can be made by joining individual parts or components or using a mold and pouring a suitable material like aluminum, plastic or any similar materials to form a one piece device. 1. The receiving end 6 of the supporting base 2 is chamfered allowing for smooth insertion of the animal without becoming snagged. FIG.

The only humane tool for fast humane slaughtering of domestic meat rabbits, chickens, Young Turkeys and fowl employing the mechanical cervical dislocation method. The commercial meat rabbit industry is without validated on-farm euthanasia methods, potentially resulting in inadequate euthanasia protocols. Worldwide, an estimated 9.1 billion birds may need to be killed on farm each year. In the EU, manual neck dislocation may only be used to slaughter birds less than 3kg liveweight. At times it may be desired to slaughter the rabbit or any other small animal by utilizing the “Sharp Pull” method (2) whereby the operator inserts the animals head into the device then slides the animal toward the closed end just until the animal's neck fits snuggly in to the device, then positioning the body of the animal perpendicular to the device, grabbing the rear legs or any suitable part of the animal then swiftly and sharply pulling the animal upward, using your free hand to hold the animal in place thus breaking the neck, instantly and humanely incapacitating, and killing the animal. Manual Neck Dislocation. If the operator should require a wider or narrower opening of the device, the rod 3 may be adjusted using force either by hand or by inserting the rod 3 into a larger diameter and length pipe of sufficient rigidity and strength then with the added leverage afforded by the pipe, the opening 1 of the device is adjusted. Four mechanical poultry killing devices; modified Armadillo (MARM), modified Rabbit Zinger (MZIN), modified pliers (MPLI) and a novel mechanical cervical dislocation (NMCD) gloved device, were assessed for their killing potential in the cadavers of euthanised birds. The supporting base 2 of the device made from a piece of angled material in the shape of an “L” is the support for which the rod 3 is attached, by means mechanical fasteners, welding, epoxy and similar means.

Materials and Methods Three mechanical devices: Modified Armadillo (MARM), Modified Rabbit Zinger (MZIN), a novel mechanical cervical dislocation device (NMCD) and a control (MCD) … The present invention provides a portable device preferably made of steel or any rigid materials. An alternative emergency method for killing poultry on-farm is required following European legislation changes (EU 1099/2009), which heavily restricts the use of manual cervical dislocation. The animal is stunned by the trauma and dies as a result of the brain being separated from the rest of the body and massive internal bleeding. By making the device entirely of metal or similar material, it is both light and inexpensive as well as very sturdy. This invention relates in general to a rabbit euthanasia and slaughtering apparatus and is more particularly described as an apparatus for slaughtering rabbits and the like, by means of cervical dislocation, whereby in the “hyper extension” method (1) the operator places the animal into the device opening, slides the animal toward the closed end of the apparatus and subsequently pulls the animal forcefully while hyper extending the neck until a separation occurs at a critical point of the cervical spine causing irreparable damage to the cervical vertebrae, causing instant incapacitation and a quick humane death without causing undue stress, anxiety, or pain to the animal. The flat surface 9 of the back of the supporting base 2 allows for a secure installation to any surface. This device may be used for, but is not limited to slaughtering rabbits, hares, guinea pigs, ducks, geese, etc. cervical dislocation device resulted in consistent anatomical damage to the birds (eg high dislocation of the neck and severing of the spinal cord) compared to the manual method, despite both having 100% success rate, while the modified Rabbit Zinger TM was difficult Trials were conducted on three commercial meat rabbit farms using 170 cull rabbits. You can only use non-penetrative captive bolt devices for simple stunning on cattle, sheep, goats and deer under 10kg. Four mechanical poultry killing devices; modified Armadillo (MARM), modified Rabbit Zinger (MZIN), modified pliers (MPLI) and a novel mechanical cervical dislocation gloved device (NMCD), were assessed for their killing potential in the cadavers of euthanised birds of 4 type/age combinations: layer/adult, layer/pullet, broiler/slaughter-age and broiler/chick. Referring now more particularly to the drawings, an inverted wedge shaped structure 1 for receiving the animals head is formed of steel or similar rigid material and comprised of two readily available or produced materials shaped and secured together by any available means to provide a supporting base and an outwardly curved rod projection which can be round or square shaped.
