Abstract: The distribution of vessels in the oviducts were studied in 20 Beijing ducks. The results are as follows: The arteries suppling oviduct of the Beijing ducks contained oviductalis cranialis,media, caudalis and vaginalis. The veins drainaging oviduct were stretched along the above ateries and the vessels were situated on the left side of the body, but there was no caudal oviductal vein. The anterior oviductal artery arose from the pubic artery of the left external iliac artery and distributed to the infundibulum and the magnum of the oviduct. The middle oviductal artery arose from the left caudal renal artery and distributed to the isthmus and shell gland of the oviduct. The caudal oviductal artery arose from the left external pudendal artery or left internal iliac artery and distributed to the caudal part of uterus and the cranial part of vagina. The vaginal artery arose from the left internal pudendal artery of median sacral artery and distributed to the caudal part of vagina.
