Dr. David Patterson

Extension educator, reproductive management, University of Missouri. Dr. Patterson is a member of the faculty in the Division of Animal Sciences at the University of Missouri-Columbia. Patterson, a native of Montana, completed his bachelor's and master's degrees at Montana State University. Research for his master's was conducted at the Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont. He received his doctorate in reproductive physiology from Kansas State University. Dr. Patterson’s research efforts have gained wide industry acceptance and resulted in new strategies to synchronize estrous cycles of postpartum beef cows and replacement beef heifers. His research program has received funding for the past 10 years from USDA’s National Research Initiative Competitive Grants Program in Animal Reproduction and led to the development of four progestin-based protocols to facilitate fixed-time artificial insemination in beef heifers and cows. Dr. Patterson led the development of Missouri’s Show-Me-Select Replacement Heifer Program, which is the first comprehensive, state-wide, on-farm beef heifer development and marketing program in the U.S. Participation in this program from 1997-2010 involved roughly 700 farms, 200 veterinarians, 30 regional Extension livestock specialists, and more than 90,000 heifers. The marketing component of the program facilitated the sale of more than 21,000 heifers in sales across Missouri from 1997 through the spring sales in 2010. Impact on Missouri’s economy from the past 12 years of this program exceeds $40M.

Peter Sutovsky

Associate Professor, Division of Animal Sciences, University of Missouri-Columbia.

Dr. George E. Seidel Jr.

Distinguished professor, Colorado State University. Dr. Seidel was raised on a dairy farm in Pennsylvania. He received a bachelor's degree in dairy science from Pennsylvania State University in 1965, and a master's degree (1968) and doctorate (1970) from Cornell University, Ithaca, N.Y. His master's thesis concerned methodology of semen collection from bulls and biochemistry of semen. His doctoral thesis concerned the endocrinology of superovulation of prepuberal calves and culture and transfer of the resulting embryos. He went on to Harvard Medical School to study rabbit oocytes with electron microscopy. For the past 39 years, he has been at the Animal Reproduction and Biotechnology Laboratory, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins. Initially, work in Colorado was primarily on reproductive physiology of bulls and stallions. In 1973, the Embryo Transfer Laboratory was established. Farmers brought their valuable donor cows to this laboratory for superovulation and recovery of embryos, which then were placed into the uteri of less valuable cows for gestation. Over the next decade, more than 6,000 bovine embryos were collected and transferred in this manner. Fees for these services funded the bulk of the teaching and research of the Laboratory. Techniques such as nonsurgical recovery and transfer of bovine and equine embryos and cryopreservation of embryos were developed, refined and taught to others. The Laboratory became known for developing a simple, reliable procedure for bisecting embryos to produce identical twins in a variety of species. In 1978, Dr. Seidel spent a sabbatical leave at Yale. In 1986 he spent a sabbatical leave at the Whitehead Institute at MIT. Dr. Seidel was elected to the U.S. National Academy of Science in 1992. In the late 1990s, his laboratory made a huge, largely successful effort to make sexing sperm by flow cytometry/cell sorting practical for artificial insemination. Current research projects include in vitro oocyte maturation and fertilization, regulation of carbohydrate metabolism of preimplantation embryos, gene expression in early embryos, and cryopresevation of oocytes and embryos by vitrification. Dr. Seidel and his wife, Sarah, also own a cattle ranch including a registered Angus herd.

Cliff LambDr. Cliff Lamb

Assistant director and professor, University of Florida North Florida Research and Education Center. Dr. Lamb graduated with a bachelor's in animal science from Middle Tennessee State University. He received his master's degree in 1996 and doctorate in 1998 at Kansas State University. In 1998, after completing graduate school, Dr. Lamb became a beef specialist/assistant professor at the University of Minnesota. He was promoted to associate professor in 2003. In 2008, Dr. Lamb moved to the University of Florida where he was promoted to professor in 2009. His primary research efforts focus on applied reproductive physiology in beef cattle, emphasizing efficient management systems for replacement heifers and postpartum cows. In addition to research and Extension, Dr. Lamb is the assistant director at the University of Florida North Florida Research and Education Center in Marianna.
