Anatomical and radiographical studies on the arterial supply of the udder in goat and their surgical importance

The present study aimed to show the arterial blood supply of the udder of the Egyptian native breed of goat (Baladi goat) to be used as a guide during mastectomy and other surgical interferences. The study was carried out on the udder of twelve apparently healthy adult female Egyptian Baladi goats. Four goats were used for mastectomy, one specimen was used for radiography and the other specimens were subjected to gum-milk latex injection to clarify the origin, course and distribution of the main arteries supplying the udder. The results revealed that the udder of goat was supplied by the external pudendal artery and dorsal labial and mammary branch of the ventral perineal artery. The course of the external pudendal artery through the inguinal canal before reaching the base of the udder, as well as that of the dorsal labial and mammary branch of the ventral perineal artery in the perineal region, were briefly described to determine the appropriate site for ligation of these vessels before mastectomy. Moreover, the arterial interconnection between the two halves of the udder was emphasized to be highlighted during unilateral mastectomy. Vascular ligation of the main blood vessels supplying the udder on the basis of the anatomical description provided less traumatic surgery and reduced the severity of the blood loss.
