Lymph Nodes of Cattle, Hogs, Sheep, and Horses
Lymp Nodes of Cattle, Hogs, Sheep, and Horses – The lymphatic system is widely used as an evaluation tool in meat inspection. In many cases the decision whether a carcass is wholesome or not is determined by what is found upon examination of the lymph nodes and associated structures.
It is important, therefore, that meat inspection personnel know the anatomical location of lymph nodes in the various species of animals presented for slaughter.
Also, when making carcass dispositions, the veterinarian must frequently rely on his or her knowledge of the afferent and efferent drainage of lymph nodes so that he or she can determine the pathogenesis of a disease process.
The purpose of this revised guideline is to update the original version and to expand it somewhat to include the equine. Since the original Guideline 5 was written, many of the names of the lymph nodes have been changed.
