Comparative histomorphological study of uterus between laying hen and duck.
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 (14.98 +/- 2.58 g) and uteral width (5.00 +/- 0.91 cm) were greater than duck. It was observed in duck (9.27 +/- 2.04 g) and (3.19 +/- 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 (164.47 +/- 34.16 microm) was greater than duck (119.80 +/- 27.89 microm).
