| Abstract | ||
| Ostrich considered as a high value bird in comparison with other birds and domestic animals because of having low cholesterol and fat and more Fe level meat. Utero-vaginal junction Has sperm storage tubules which store spermatozoa. As There are not any simultaneusly research done on this part in breeding season and Non-breeding seasons, these organs were studied anatomically and histologically. For this, every month four oviducts of adult ostrich were provided (overall 48 oviducts) and Utero-vaginal junction was anatomically studied. Then tissue samples were taken. Samples were obtained, using Haematoxylin and Eosin Stain Kit. The anatomical results suggest there is a sigmoid curve in the start of the vagina. Histological results showed the epithelium of this part is pseudostratified ciliated columnar and in some Month,s epithelium was simple ciliated columnar. Epithelium of tubules were simple non- ciliated columnar. Statistical analysis result suggest The length and width of this part and The number and diameter of sperm storage tubules in first half of year is larger from second half year. Maximum average size belongs to 23 July-25August and minimum to 22 December-20 January. | ||
