Reproduction & Behavior

New Bolton Center, reproduction

New Bolton Center's Section of Reproduction & Behavior provides comprehensive reproductive services for mares and stallions.

Based at the Georgia and Philip Hofmann Research Center for Animal Reproduction, the section’s clinicians have extensive clinical experience enhanced by the latest in research and technology.

The section provides a wide range of reproductive services, from natural breeding to advanced assisted reproductive techniques like embryo transfer. Stallions are a specialty, and the section has extensive experience in dealing with male fertility and behavior problems. The equine behavior service is considered one of the best in the world. The section’s faculty members are board certified by the American College of Theriogenologists.

The Georgia and Philip Hofmann Center for Animal Reproduction at Penn Vet’s New Bolton Center offers a full range of embryo transfer services. Clients can choose to use one of Hofmann Center’s resident recipient mares or provide their own recipient mare. We accept embryos transported from other facilities and recover embryos for domestic transport. Embryo vitrification is available upon request.

At New Bolton Center, reproduction specialists work closely with board certified surgeons and internists to provide comprehensive care for dystocias and other reproductive emergencies. The section’s ongoing basic and applied research contributes to the advancement of the theriogenology specialty.

Providing service to the North American animal industries is the Reference Andrology Laboratory. This laboratory provides complete testing of semen from mammalian and avian species which serves as an aid to practitioners working on reproductive issues.

New Bolton Center’s High-Risk Pregnancy Program manages the mare that may have problems with foaling. The ICU is equipped with a specially modified ECG telemetry unit used to monitor and record up to eight fetal heart rates simultaneously without disturbing the mares. Stalls housing the pregnant mares are equipped with low light cameras to monitor signs of labor in a natural setting.

Our team includes five board certified specialists in reproduction or behavior, working in collaboration with sports medicine and imaging, medicine, and surgery colleagues at New Bolton Center, to offer a comprehensive approach to case management.
