The Mizzou Repro mission is to improve the profitability and sustainability of beef cattle farms and ranches in the state of Missouri and across the United States. Reproductive performance is one of the critical drivers of profitability and sustainability, and failure to attain pregnancy early in the breeding season represents some of the largest losses in potential efficiency in the U.S. cow herd. Reproductive technologies provide an opportunity to mitigate this loss as well as facilitate long-term improvements in genetics and management. Currently, these technologies are underutilized in the beef industry, and U.S. beef producers must begin to take advantage of these opportunities in order to remain cost-competitive in a global beef market. We are committed to developing effective extension and education programming that equips producers, veterinarians, and allied industry with the knowledge and tools needed to increase use of reproductive technologies in beef production systems. In addition, we are committed to ongoing applied research efforts to improve success rates with these technologies and characterize the impact on reproductive performance and genetic improvement.

Jordan Thomas

Jordan Thomas is an Assistant Extension Professor and State Beef Reproduction Specialist in the Division of Animal Sciences at the University of Missouri. Dr. Thomas is a Missouri native and University of Missouri alumnus, having earned his Ph.D. in Animal Sciences with an emphasis in Reproductive Physiology in 2017. In addition to extension and education programming associated with the National Center for Applied Reproduction and Genomics, Dr. Thomas maintains an active applied research program in reproductive management of beef cattle. The primary research focus of the Thomas lab is control of the bovine estrous cycle, specifically to facilitate use of reproductive technologies such as timed artificial insemination and embryo transfer.

Graduate Students


Rachael Bonacker

Rachael Bonacker is a native of Cedar Hill, Missouri and an alumna of the University of Missouri’s Division of Animal Sciences. Rachael is a dual DVM and M.S. student, completing her graduate research in Animal Sciences while concurrently enrolled at the University of Missouri College of Veterinary Medicine. Her research is focused around presynchronization strategies for postpartum beef cows prior to timed artificial insemination or embryo transfer. Rachael is co-advised by Dr. Jordan Thomas and Dr. David Patterson in the Division of Animal Sciences.
