عنوان مقاله [English]
Guinea fowls are considered of pheasant birds. Reproductive system of birds includes ovary and oviduct. The ovary is connected to the cloaca by oviduct and consists of infundibulum, magnum, isthmus, uterus and vagina. Due to anatomical differences in these organs of birds, and because there is scarce knowledge about the oviduct of guinea fowl, this research was performed. For this research 10 female guinea fowl were selected and oviducts were anatomically studied. Then tissue samples were taken, and stained by Hematoxylin and Eosin. Anatomical and histological results were generally similar with other birds. The most prominent anatomical feature of oviduct was the same length of oviduct and body and all oviduct regions except uterus had in the same color. The statistical analyses using Tukey test showed the average size of different parts of active oviduct is greater than inactive oviduct, also this result is significant in magnum, isthmus and uterus and is not significant in the infundibulum and vagina. Histological result showed that the epithelium in oviduct has been seen ciliated pseudostratified columnar. Also Except infundibulum in oviduct, s lumen, there were secondary chains on the primary chains. In lamina propria there were tubular glands that started from the tubular part of infundibulum and disappeared in vagina.
