Morphometric and Histological Study of Reproductive Organs of Indigenous Ewes

Morphometric and histochemical studies provide valuable insights into the structural and functional characteristics of reproductive organs of animals. The experiment was conducted with the aim to evaluate the morphometry of ewe reproductive organs in relation to age and to investigate the effect of age on the histological structure of the ovary, oviduct and uterus. From 9 (nine) reproductive organs of ewe 18 ovaries, 18 oviducts, 18 horns of uterus and 9 uterine bodies were obtained from the local abattoir of Mymensingh municipality, Bangladesh and then categorized based on age (confirmed through dentition pattern and butcher’s report) into two categories: 1-2 years and 2.5-4 years. In the morphometric study, the weight, length and width of ovary, oviduct, body of the uterus, and uterine horns were significantly higher (p0.05). In the histological study of ovary, the number of normal primordial, primary, secondary, and antral follicles were non-significantly (p>0.05) higher in ewes at the age of 2.5-4 years than 1-2 years. In case of thickness of layer in oviduct, the serosa and mucosal folds were non-significantly (p>0.05) thicker in the older age compared to the younger group. However, the muscularis layer was significantly (p
