Common vessels for venipuncture in a chicken?

Common vessels for venipuncture in a chicken?

• A. Jugular vein only
• B. Jugular, wing, medial metatarsal veins
• C. Carotid artery
• D. Cephalic vein

Answer: (B)

Chickens have several accessible veins that veterinarians and researchers commonly use for blood draws. The jugular vein is the workhorse site because it’s large, easy to locate on the neck, and provides a steady flow of blood with straightforward technique. When the jugular isn’t ideal—for example, if the bird is large, stressed, or the neck isn’t ideal for restraint—the wing vein offers a convenient alternative along the leading edge of the wing. The medial metatarsal vein runs along the leg and is another reliable option for obtaining blood, especially when head and wing access is difficult. The carotid artery is not used for venipuncture because it’s an artery, not a vein, and drawing from it can cause significant bleeding and erroneous results. The cephalic vein can be present in birds, but in chickens it’s not as consistently used or reliable as the jugular, wing, and medial metatarsal veins. So, the best answer includes these three common venipuncture vessels: jugular, wing, and medial metatarsal veins.
