UC Davis Veterinary Assisted Reproduction Laboratory

We may be known as an equine reproduction lab… but apparently we also speak goat now 🐐
We successfully completed goat IVF from start to finish. Oocytes were aspirated from live does, embryos were produced in the lab, vitrified, and later transferred by the Herd Health and Reproduction Service at the VMTH. Pregnancy was confirmed, and last Friday we had the chance to be there for kidding.
This was a true team effort. Special thanks to Dr. Kazuki Takahashi for leading embryo production in the lab, and to the Herd Health and Reproduction Service for embryo transfer and clinical care.
From horses to goats, we are expanding our reproductive toolbox across species.

Happy New Year & Thank you for an incredible 2025
From research to clinical service, teaching, and innovation, none of this would be possible without our students, collaborators, clinicians, and clients.
We’re excited for everything 2026 will bring!

2025 Research Milestones
Equine IVP Morphokinetics
We showed that early cleavage patterns and timing during the first mitotic divisions are linked to blastocyst development, pregnancy rates, and early pregnancy loss in equine IVP embryos.
These morphokinetic features provide a practical tool for embryo selection, helping close the gap between in vivo and in vitro embryo outcomes. https://doi.org/10.1111/evj.70004
Equine placentitis
In “Beyond nocardioform,” we showed that other microbes are involved in equine mucoid placentitis, offering new insights into placental disease mechanisms and pregnancy loss. https://doi.org/10.1111/evj.70112
Endometrial organoids
We demonstrated that equine endometrial organoids keep the structure and cycle-stage identity of real endometrium. A powerful new tool for studying the mare’s uterus and improving reproductive science. https://doi.org/10.1093/biolre/ioaf232
Together, these studies reflect our commitment to connecting fundamental biology with clinical impact in equine reproduction.

We showed that early cleavage patterns and timing during the first mitotic divisions are linked to blastocyst development, pregnancy rates, and early pregnancy loss in equine embryos.
These morphokinetic features provide a practical tool for embryo selection, helping close the gap between in vivo and in vitro embryo outcomes. Now we have implemented these factors into our embryo grading, which helps select the best embryos for pregnancy and foaming potential! https://doi.org/10.1111/evj.70004
