Lymphatic parietal nodules of the bones pelvic member in the veterinary inspection of the sheep

Abstract

In Republic of Argentina, ovine meat production is driven by sector politics in order to increase the slaughtered volume and the per capita consumption. Sanitary inspection is essential to certify the meat’s innocuousness. In the post-mortem, the lymph nodes (LN) examination is essential in order to establish sanitary criteria on the cattle that have been inspected by the veterinary inspector in the slaughterhouse. For this purpose, the shape, size, location, afferences and efferences of each lymphocenter were identified and described. For the study, 8 adult specimens of both sexes were used, which were euthanized and injected with chinese ink in order to visualize the lymphatic drainage for further dissection. The external parietal lymphocenters of the pelvic limb were identified and described, such as the pre-femoral and popliteal LN. The internal parietal lymphocenters of the same limb were also identified and described, such as retro mammary LN, superficial inguinal LN, ischial LN, external iliac LN, internal iliac LN and middle iliac LN. The obtained results differ in part from those described by other authors; this is mainly due to the inconstancy and lack of description of lymphocenters by them. Nevertheless, the description will allow adapting the post-mortem veterinary inspection system in slaughter beach and in this way to establish the sanitary criteria of slaughtered and inspected cattle.
