The objective of the current study was to present baseline data on themorphology and surface architecture of the oviduct in adult female Balady duckgrossly and by using scanning electron microscope (SEM). Fifteen apparentlyhealthy adult female Balady ducks were used which weighted (2-4 kg). Twobirds were formalized while the other birds were used in the fresh state fordissection then careful evisceration of the oviduct. For SEM five of the latterwere used immediately after immersion in saline. Our data anatomicallyrevealed that infundibulum had funnel and tubular parts, magnum was highlyconvoluted pale white or creamy color, less convoluted isthmus, dilated uterusand S-shape spiral vagina. The inner wall of the duct contains longitudinalfolds in the first four parts while the vagina showed transverse thick folds. colorof the mucosa was reddish in infundibulum, magnum and isthmus whilegreenish brown in color in the uterus and whitish yellow in the vagina. SEMshowed primary and secondary folds allover the oviduct which became morethicker in the uterus and carrying tertiary folds in the vagina.
