U.S. Pat. No. 5,246,396:  Method for the humane slaughter and processing of domesticated ostrich.

 ostrichyum

1. A method for humanely slaughtering and efficiently processing ostrich on a large scale in a facility, comprising the steps of:

          stunning said ostrich via an electrical discharge;
          hanging said ostrich in an inverted position by placing a first shackle around one leg of said ostrich, hoisting said ostrich to an inverted position, affixing said shackle to a rail system to permit mobility, placing a second shackle around the free leg of said ostrich, and affixing said second shackle to said rail system to enhance the stability of said ostrich hanging in said inverted position;
          bleeding said ostrich by cutting the arteries in the neck region and the windpipe of said ostrich and permitting the blood of said ostrich to leave said ostrich;
          decapitating said ostrich;
          de-feathering said ostrich by isolating said ostrich via air curtains, providing a pressurized air dispenser having a needle-like probe, injecting air between the ostrich hide and the ostrich muscle structures by inserting said probe into the base of the neck region of said ostrich, into the base of both wing regions, and into both lower leg regions below the metatarsal joint, such that said probe penetrates said hide and rests at the outside of said muscle structures, and pulling said feathers from said hide;
          tieing the colon, urinary track, and reproductive organs of the ostrich by making a circular cut around the vent opening of said ostrich, grasping the colon, urinary track, and reproductive organs, pulling said colon, urinary track, and reproductive organs approximately two to six inches from said ostrich, and affixing a constricting device around said organs;
          removing the feet and wings from said ostrich;
removing the neck region of said ostrich by making a vertical cut along the length of the neck region of said ostrich, separating the esophagus and windpipe from the muscle tissue in said neck region, tieing said esophagus, while permitting said windpipe to remain functionally attached to said ostrich, and removing said neck region while permitting said esophagus and said windpipe to remain functionally attached to said ostrich;
          skinning said ostrich;
          removing the viscera from said ostrich by cutting vertically along the entire frontal region of the ostrich below the ostrich membrane from the anal region to the breast plate, around said breast plate, and to the neck region, said membrane being the layer below the ostrich hide, pulling said gizzard out from said ostrich, tieing said gizzard at the gizzard base, and cutting said gizzard above the tie off point to thereby separate said gizzard from said ostrich; and
          removing the edible meat products from said ostrich.

2. The method of claim 1, further comprising the steps of:

placing said ostrich in a restraining box for restricting movement of said ostrich, said restraining box having a hole;
extending the head and neck of said ostrich through said hole and outside of said restraining box;
applying an electrical shock to a region of said ostrich which is outside said restraining box to thereby stun said ostrich;
removing said ostrich from said restraining box; and
hoisting said ostrich to said inverted position.

3. The method of claim 1, further comprising the steps of:

cutting the hide from the flank and back regions of said ostrich beginning at the loin region and working downward to the neck region; and
pulling said hide away from said muscle structures.

4. The method of claim 1, further comprising the steps of:

(i) at the front of said ostrich at a first side, cutting vertically downward beginning at the top part of the loin region, through the hip joint, and then horizontally across the rib region;
(ii) at the back of said ostrich, cutting horizontally across said rib region, vertically upward through said hop joint, and to said top part of said loin region, thereby freeing said flank, loin, and leg muscles from a first leg of said ostrich; and
(iii) repeating steps (i) and (ii) at the second side of said ostrich to thereby free said flank, loin, and leg muscles from a second leg.

5. The method of claim 1, further comprising the steps of:

grasping the beak area of said ostrich; and
cutting the neck region of said ostrich with a knife.

6. The method of claim 1, further comprising the steps of:

removing the eye balls from the head of said ostrich after decapitation;
placing said eye balls in an ice bath; and
after sufficiently reducing the temperature, packaging said eye balls.

7. The method of claim 1, further comprising the steps

cutting the hide on a first leg having said first shackle, the cut being from the foot region to the thigh region;
removing the foot from said first leg;
affixing a trolley hook between said first leg and said rail system;
cutting the hide on a second leg having said second shackle, the cut being from the foot region to the thigh region;
removing the foot from said second leg; and
affixing a trolley hook between said second leg and said rail system.

8. The method of claim 1, further comprising the steps of:

associating an identification tag with said neck region after removal, said identification tag identifying the ostrich from which said neck region was obtained;
permitting said neck region to remain dormant until final inspection of said ostrich; and
packaging said neck region for shipment if said final inspection is satisfactory.

9. The method of claim 1, further comprising the step of removing said heart.

10. The method of claim 1, further comprising the step of removing said liver.

11. The method of claim 1, wherein said first and second shackles comprise a chain connecting a small end hook and a rolling mechanism and wherein, when either said first shackle or said second shackle is affixed to said respective leg, said chain is wrapped about said respective leg and said small end hook is hooked to a chain link of said chain.

12. The method of claim 4, further comprising the steps of:

refrigerating said loin, leg, and flank;
removing the leg bone; and
cutting said loin, leg, and flank in accordance with the muscle groups.

13. The method of claim 4, further comprising the steps of:

skinning said first and second legs to the base of the corresponding thigh; and
removing both ostrich wing.

14. The method of claim 11, further comprising the step of lifting said ostrich by exerting upward force on said rolling mechanism of said first shackle.

15. The method of claim 1, comprising the steps of:

using a shackle to hoist and then suspend said ostrich, said shackle having a chain connecting a small end hook and a rolling mechanism;
wrapping said chain about said leg and hooking said small end hook on a link in said chain; and
lifting said ostrich by exerting upward force on said rolling mechanism.

16. A method for humanely slaughtering an ostrich, comprising the steps of:

placing said ostrich in a restraining box for restricting movement of said ostrich, said restraining box having a hole;
extending the head and neck of said ostrich through said hole and outside of said restraining box;
applying an electrical shock to either said head or said neck, or both, of said ostrich to thereby stun said ostrich;
removing said ostrich from said restraining box;
lifting said ostrich to an inverted position on a rail system for transporting said ostrich through processing areas; and
killing said ostrich while in said inverted position by making a cut across arteries in said neck and bleeding said ostrich.

17. The method of claim 16, further comprising the step of beheading said ostrich.

18. The method of claim 16, comprising the steps of:

using a shackle to lift and then suspend said ostrich, said shackle having a chain connecting a small end hook and a rolling mechanism;
wrapping said chain about said leg and hooking said small end hook on a link in said chain; and
lifting said ostrich by exerting upward force on said rolling mechanism.
