Abstract


The study was carried out on the mammary glands taken from two buffalo cows and one bovine (the Bălţată Românească breed), all adults. The distribution of the arterial vascular system of the mammary glands was emphasised by injecting into the arterial system a solution obtained by mixing the commercial product “Palux” with red dye, then keeping the glands in 5% formaldehyde for 24 hours, and finally dissecting them. The arterial vascularisation of the mammary gland in big ruminants is realised by the external pudendal artery which eventually divides into the posterior and anterior mammary arteries. After splitting into branches that ensure the vascularisation of the supramammary lymphnodes, the posterior mammary artery participates in the vascularisation of the caudal quarters. The anterior mammary artery continues with one or two branches ensuring the vascularisation of the medial region of the gland, and finally forks off into the lateral mammary artery and the medial mammary artery. In all three glands under investigation vascular communication between the two glandular halves has been identified, but the branches are of small calibre and cross the median suspensory ligament.
