Anatomy of Ovary of Pati and Chara-Chemballi Ducks (Anas Platyrhynchos Domesticus) During Laying Periods

The present investigation was undertaken to establish anatomical norms on gross anatomical, histological and histochemical parameter of ovary of Pati and Chara-Chemballi ducks. In present investigation, twelve each Pati and Chara-Chemballi ducks in their laying periods at 42 weeks of age were utilized. After collection of sample, it was processed as per slandered method. The mean value of length, breadth, thickness and weight of ovary of Chara-Chemballi ducks was significantly higher than Pati ducks. Histologically, the ovary was covered by simple squamous epithelium with patches of cuboidal epithelium in both the ducks. The outer cortical and inner medulla divisions of the ovary were obscured. PAS positive reaction were intense at the basement membrane of granulosa cells, strong in stratum granulosum and theca interna, and moderate in ovarian stroma, tunica albugenia and the cytoplasm of the oocytes in Chara-Chemballi duck as compared to Pati duck. Result obtained showed that the Chara-Chemballi duck revealed significant difference in gross and histochemical parameters as compared to Pati ducks but histologically, there are no significant differences of ovaries both the varieties.
