Arterial supply to the cloacal bursa of the Lhoman White LSL lineage fowl (Gallus gallus Linnaeus, 1758). A study has been carried out on the origin, number and disposition of the arterial branches supplying the cloacal bur- sas of 30 female fowl (Gallus gallus) of the Lhoman White LSL lineage, aged between eight and ten weeks. The right isquiadic artery was cannu- lated and injected with a 50% colored solution of Neoprene latex “450”. Next, the samples were fi xed with a 10% formalin solution through deep intramu- scular, subcutaneous and intracavitary injections for a period of at least 48 hours. Dissections confi rmed that the cloacal bursa was supplied by direct branches from the right bursocloacal arteries in 29 cases (96. 67 %), the left bursocloacal arteries in 28 cases (93.33%), the right cloacal arteries in 13 cases (43.33%), and the left cloacal arteries in 15 cases (50%). The number of branches from the arteries, independent of their origin, varied from two to six. There were two branches in 5 cases (16.67%), three branches in 14 cases (46.67%), four branches in 3 cases (10%), fi ve branches in 6 cases (20%), and six branches in 1 case (3.33%). The distribution of the vessels was unique in each sample.
