Arterial vascularization of the cloacal bursa in Gallus gallus domesticus (breeding stoch of the Avian Farms linage)

The cloacal bursa’s arteries of 30 females Gallus gallus domesticus of the Avian Farms linage were injected with 50% Neoprene Latex solution, and submitted to dissection. The age of the birds was from 10 to 12 weeks. The vessel’s origin, number and sequence were studied. The results showed the participation of the left and right bursocloacal arteries in all cases, with the association of the caudal mesenteric artery (13.33%) and median caudal artery (3.33%). The total branches number, without considering its origin, varied in 2 to 5, being 2 to 3 branches the major frequency.
