As soon as the animal is down, bleed it without delay. Stand behind the animal as in Figure 2 and with the sharp skinning knife make an incision through the hide in the middle of the dewlap immediately in front of the breastbone. Hold the knife so the point is directed toward the rear of the animal, insert the knife under the breastbone toward the rump of the animal and cut toward the backbone. This will cut the arteries that cross just beneath the point of the breastbone. http://www.lynmachinery.com/slaughtering-equipment/pig-slaughtering-equipment/
