Arterial supply to the cloacal bursa of Hybro PG lineage hens (Gallus gallus)

Abstract

A study was carried out on the origin, number and disposition of the arterial vessels and their branches which irrigated the cloacal bursas of 30 hens (Gallus gallus) of the Hybro PG lineage. First of all, the left isquiadic artery from the samples was cannulated and injected with a 50% colored solution of Neoprene latex “450”; then, we continued the experiment with dissection whose results confi rmed that the cloacal bursa was supplied by direct branches from the left and right internal pudendal arteries and bursocloacal arteries in 100% of the cases, varying only in terms of the numbers and disposition of their branches. There were also some branches from the median caudal artery (23%) and left external pudendal (3.33%). The total number of branches varied from 1 to 4 and their distribution was unique in each sample.
