Dr. Jason Bruemmer portrait

Dr. Bruemmer has been a part of the Equine Sciences program for over two decades. His work in Mustang herd management has recently led him to a new position with the USDA-APHIS National Wildlife Research Center as their project leader in fertility control. Fortunately for us, Dr. Bruemmer will continue to teach Equine Reproduction and will also serve on our Equine Sciences Advisory Committee.

Dr. Jason Bruemmer grew up in the horse industry in Texas and has continued to serve the industry as a scientist, researcher, lecturer and horseman. As a horseman, Dr. Bruemmer has been a cornerstone of the outreach program at CSU, working with breeders, owners and clients to increase their knowledge of equine reproduction and management. His ability to interact and relate to horse owners and breeders has informed his research. Dr. Bruemmer was instrumental in developing a protocol to harvest epididymal sperm from stallions who had died, allowing the owner to preserve the valuable genetics for future production. Stallion behavior, physiology and management are major fields of interest to Dr. Bruemmer. His research in the cryopreservation of stallion semen and membrane integrity continues to work for improvement in stallion semen extenders. Stallion behavior is an often overlooked component of reproductive management and fertility assessment. Dr. Bruemmer’s ongoing work in this field continues to have very productive results with stallions referred for breeding problems. An avid horseman and polo player, Dr. Bruemmer still finds time to work with the CSU Polo Team and finds time for the occasional chukker himself.
