Diseases of domesticated birds (1920) Diseases of domesticated birds diseasesofdomest00ward Year: 1920 KILLING POULTRY 315 inside of the mouth is adopted, the blood vessels in the brain which are cut find an outlet for their contents through the knife hole. Bleeding from these vessels is, under any circumstances, of assistance in obtaining the best results, and where the neck vessels are missed the condition of the chicken is often greatly improved by the bleed- ing from the brain. DISCUSSION OF THE ILLUSTKATIONS LOCATION OF VEINS The location of the principal veins in the neck of the chicken, their relation to the skull, and the point at which it is desirable to make the cut for bleeding, are shovn in the accompanying illus- trations. Figure 65 shows the head and neck of a young cock about a year old. Two large veins (heavily lined with black in the figure) run the whole length of the neck, one on each side, and unite by a ' bridge-vein' which is just below and behind the ear. This vein, which connects the two others, does not run straight across but at an angle, so that it is farther front on the left than on the right side. If the feathers on the neck of a chicken are pushed aside, or, better still, if a molting chicken with but a few feathers is observed, these veins can be, seen at each side of the neck while the bird is alive, especially if a little pressure is used at the lower part of the neck so that the blood collects and distends them. It is important that the position of these veins be exactly located on the neck of the live bird, since upon this information will depend very largely the proper guiding of the knife to the blood vessel.
