The present investigation was carried out on oviductal duck and laying hen to comparing of histomorphological structures of them. For this purpose, a total of forty adult healthy ducks and hens (each of them twenty), aged 1-1.5 years, were used. After dissecting them, some morphological parameters such as: total weight and length of oviduct were measured and then in each of specimen some morphological parameters such as; length, width and thickness of uterus were measured. For histological studies, after tissue preparation and staining with H and E, histological layers of uterus were recognized and the size of them with micrometry method were determined. By using t-test and analyzing factors between duck and hen we concluded that total weight and length of oviduct in hen was greater than duck and the difference was significant (p< 0.05). By comparing of dimensions and weight of uterus between duck and hen revealed that, in hen the mean of uteral weight (14.98أƒâ€ڑأ‚آ±2.58 g) and uteral width (5.00أƒâ€ڑأ‚آ±0.91 cm) were greater than duck. It was observed in duck (9.27أƒâ€ڑأ‚آ±2.04 g) and (3.19أƒâ€ڑأ‚آ±0.58 cm), respectively. In histometrical studies, the length of tunica mucosa, primary fold and muscularis mucosa width in duck were greater than hen. There was a significant difference in length of secondary fold and in hen (164.47أƒâ€ڑأ‚آ±34.16 أƒإ½أ‚آ¼m) was greater than duck (119.80أƒâ€ڑأ‚آ±27.89 أƒإ½أ‚آ¼m)., |
