MVS now require all mares grazing at MVS for the duration of their AI programme to be fully vaccinated for tetanus and strangles prior to arrival.


MVS recommend the below protocol for previously unvaccinated mares:

  • 2n1 (tetanus and strangles) vaccine

Mares that have been previously vaccinated using the above procedure require a yearly booster. We are able to administer the annual booster upon arrival of your mare at MVS if required.

Mary Passes Reproductive Board Exams

July 29, 2019

The team at MVS is extremely proud to announce that Dr Mary Ontiveros passed her American Board-Certification exams and is now a Diplomate of the American College of Theriogenologists. The pass rate for this year’s 14 hour exam was only 37%, so this is a fantastic achievement! We are very lucky to have Mary working not only in the NZ Veterinary Industry but right here at MVS.


Congratulations to Jasmin who just passed her American Board Exams!

Welcome Dr Sara Lyle

October 12, 2015

We are very fortunate to have Professor Sara Lyle join the Reproduction team recently from the USA helping us for time during the season while Fiona is on maternity leave.

Dr Lyle completed her veterinary degree and Masters program in Theriogenology at the University of Florida and recently completed her PhD at Louisiana State University (LSU) focused on immunological and endocrinological aspects of pregnancy. Dr Lyle was an Associate Professor at the LSU Veterinary School and has recently joined the team at North Carolina State University with her two dogs, Sammy and Gracie. These two veterinary schools have the strongest reproduction departments in the USA.

Dr Lyle is an expert in all areas of veterinary reproduction and she has published extensively in peer reviewed journals and text books and is a world renowned speaker at many international conferences in Veterinary reproduction.

Sara still has time for herself though, enjoying fishing, riding, and running (well, her dogs enjoy it when she runs). Dr Lyle brings a wealth of experience to the team and we are all very much looking forward to working with her.
