Comparison of Female Reproductive Systems in Himalayan Tahr (Hemitragus jemlahicus) and Corriedale Sheep (Ovis aries)

Yong, Hwan-Yul

Seoul Zoo, Gwacheon 427-080, Korea

Abstract

A necropsy of a primiparous, 4-year-old, Himalayan tahr (Hemitragus jemlahicus) was performed in September 8, 2009. Typical appearances of ovaries, oviducts, uterine horns, cervix and caruncles were well shown. Five cervical folds were present in the cervix. Cervical opening can be reached in the length of less than 15 cm from the entrance of vagina. Development of two follicles was found in the left ovary even though breeding season of this species naturally starts in late November. The reproductive organs of a primiparous, 3-year-old, Corriedale sheep showed that differences in the length and morphological appearance of cervix exist between two species. Comparative understanding of reproductive systems in Himalayan tahr and Corriedale sheep could help advancing assisted reproductive technologies in feral goats.

Keywords: Himalayan tahr, Corriedale, ovary, reproductive, uterus
