Tracey Chenier

Associate Professor   |   DVM, DVSc, Diplomate ACT


Tracey is a 1992 graduate of the Ontario Veterinary College. She spent 2-1/2 years in mixed animal practice before returning to OVC for graduate studies in Theriogenology. She was Board-Certified by the American College of Theriogenologists in 1996. Following completion of her DVSc graduate program, she returned to private practice, operating her own equine practice for the next 5 years. In the fall of 2002 she returned to OVC as a faculty member in the Department of Population Medicine, Theriogenology group.

Research Interests

My research interests are in the filed of equine reproduction. Current research areas include causes of abortion in mares and persistent-breeding induced endometritis.  Previous areas of research include embryo transfer and and embyro and semen cryopreservation in horses.

Current projects include:

Seroprevalence of Neospora caninum in Ontario broodmares and its possible role in equine abortion.

N-acetylcysteine as a treatment for persistent-breeding induced endometritis in the mare.

Development of diagnostic reasoning skills in recent veterinary graduates.

Current Graduate Students

Research Interests

Our Theriogenology service at the Ontario Veterianary College offers a wide range of clinical reproduction services for virtually all species. My primary focus is Equine Theriogenology, including breeding soundness evaluations, frozen semen Al, semen cryopreservation, embryo transfer, fetal sexing, pregnancy monitoring and more.



Theriogenology rotations provide students with hands-on opportunities to learn, practice and master common reproductive techniques, including ultrasonography.
