Which artery is commonly used for blood collection in rabbits due to its visibility and the ability to obtain large quantities of blood?

The auricular artery is commonly chosen for blood collection in rabbits because it is superficial and easily palpated, making it accessible for sampling. This artery runs along the ear, where it can be seen and located without much difficulty. Additionally, it allows for the collection of sufficient blood volume, which is crucial in many experimental settings where larger quantities may be needed for diagnostic or research purposes.

Using the auricular artery is also advantageous as it minimizes stress and discomfort for the rabbit, since the procedure can be performed quickly and efficiently. This is in contrast to other arteries, which may be deeper or require more invasive techniques to access, potentially leading to more complications or discomfort for the animal. The combination of visibility, accessibility, and the ability to obtain substantial blood volumes make the auricular artery the preferred choice in veterinary practice for blood collection in rabbits.
