In normal female bovine development, the developing Mullerian ducts fuse to form the single cervix and small uterine body. In this Holstein heifer, the fusion at the level of the cervix was incomplete resulting in two cervical lumens and a lack of uterine body (arrows point to anterior cervical openings). Artificial insemination would have to be done via the cervical lumen ipsilateral to the ovulating ovary to have a chance of conception in this animal. The tract has been dissected open. The vagina is to the right and the uterus to the left.
