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.

Digestive tract in avian there is from oral cavity until cloaca. Esophagus for foodstuffs transport, Crop for food temporary storage and Proventriculus and Gizzard for chemical and mechanical digestion are considerable importance in avian digestive system. In this respect there is no anatomical research performed on pheasant family as guinea fowl. For this study 20 adult male and female guinea fowl were selected and this organs were anatomically studied. Then we have done morphometrical study from esophagus, crop, proventriculus, isthmus and gizzard. Macroscopic results were basically the same as other poultry. Anatomical Special Features and different were in the crop and proventriculus. Crop was Pear shaped and proventriculus is curvature tube shaped. T student result there is no significance difference in the size of males and females in this organs. The results of this therefore , can be used as the basic anatomical knowledge is this species. Key words: Anatomy, esophagus, stomach, guinea fowl.

Guinea fowls are considered of pheasant birds. Since anatomical and histological differences were reported in the male reproductive system, and there is no anatomical and histological research performed on reproductive system of guinea fowl, this study was performed on the male reproductive system of guinea fowl in Sexual and non-sexual period. For this research 10 male guinea fowl were selected and reproductive system were anatomically studied. Then tissue samples were taken, and stained by Haematoxylin and Eosin. Anatomical and histological results were similar to other birds. Anatomical results showed the left testis was larger than the right testis, and in the sexual period it was almost twice than the non-sexual period. Epididymis was an elliptical disk shape and there was no head, body, and tail. Epididymis there was in the mediodorsal of the testis. Ductus deferens was also seen as a zigzag duct. In the histological study, there was no Mediastinum testis. Straight tubules was after seminiferous tubules and connected to rete testis, and this epithelium was Simple cuboidal epithelium or squamous epithelium. Sertoli cells with a big nucleus and euchoromatin extending to the epithelium depth, and leydig cells was spherical shape and there was in between seminiferous tubules. Epithelium of ductus deferens was similar to epididymis, but there was no epithelial gland in it.
