Which location is typically used for obtaining blood samples from larger animals like horses and cattle?

The jugular vein is the preferred site for obtaining blood samples from larger animals such as horses and cattle due to its size and accessibility. The jugular vein is a large, superficial vein located on each side of the neck, making it easy to locate and puncture for blood collection. This vein can accommodate a good volume of blood, which is important when larger specimens are needed for diagnostic testing.

In addition to its diameter, the jugular vein typically has a lower risk of complications compared to some of the other veins that can be used. The anatomical location allows veterinarians to safely access the vein while avoiding injury to nearby structures. Obtaining blood from the jugular vein also enables the collection of samples with minimal stress to the animal, which is crucial in veterinary practice.

Other veins are used for specific situations or smaller species. For instance, the ear vein may be utilized in smaller animals or specific circumstances, while the femoral vein is generally reserved for blood collection in certain quadrupeds and is less commonly used due to its deeper location. The coccygeal vein, found in the tail, is infrequently selected for larger animals unless necessary. Therefore, the jugular vein is the standard and most feasible choice for blood sampling in larger livestock.
