Abstract

The objective of the current study was to present baseline data on the morphology and surface architecture of the oviduct in adult female Balady duck grossly and by using scanning electron microscope (SEM). Fifteen apparently healthy adult female Balady ducks were used which weighted (2-4 kg). Two birds were formalized while the other birds were used in the fresh state for dissection then careful evisceration of the oviduct. For SEM five of the latter were used immediately after immersion in saline. Our data anatomically revealed that infundibulum had funnel and tubular parts, magnum was highly convoluted pale white or creamy color, less convoluted isthmus, dilated uterus and S-shape spiral vagina. The inner wall of the duct contains longitudinal folds in the first four parts while the vagina showed transverse thick folds. color of the mucosa was reddish in infundibulum, magnum and isthmus while greenish brown in color in the uterus and whitish yellow in the vagina. SEM showed primary and secondary folds allover the oviduct which became more thicker in the uterus and carrying tertiary folds in the vagina.
