James Lauderdale Dr. Jim Lauderdale

President, Lauderdale Enterprises. Jim Lauderdale earned a bachelor’s degree in animal science from Auburn University (1962) and both a master’s degree (1964) and a doctoral degree (1968) in endocrinology and reproductive physiology from the University of Wisconsin, Madison. Jim was employed in 1967 by The Upjohn Company Animal Health business as a research scientist. His research during his 31-year employment was directed at increasing the efficiency of postpartum cow and postpartum sow reproduction, the role of prostaglandin F2 in the regression of the corpus luteum and as a practical means for controlling the estrous cycle of cattle and mares and time of parturition in swine, the use of steroids for enhancement of productive efficiency of beef cattle, and the development of bovine somatotropin to enhance the efficiency of milk production of dairy cows. The research with prostaglandin F2 led to the worldwide approval for the use of prostaglandin F2, Lutalyse® sterile solution, for use in cattle, mares and swine. Jim has served as president of the American Society of Animal Science and the Federation of Animal Science Societies. He continues to be an active member of ASAS and ADSA. Following retirement in 1998, Jim formed Lauderdale Enterprises Inc., an animal health consulting firm. He continues to work in the animal health industry, primarily in the area of domestic animal reproduction management.

Dr. Lannett Edwards

Associate Professor and Graduate Director, animal science, University of Tennessee. Dr. Edwards is a native Tennessean. She obtained a bachelor's degree in agriculture and minor in chemistry at Austin Peay State University in 1989, a master's degree in dairy science focusing on reproductive physiology from Mississippi State University in 1992, and a doctoral degree in animal and molecular cell biology from the Univeristy of Florida in August 1996. She was awarded a postdoctoral fellowship by the U.S. Department of Agriculture. Her work focused on developing functional procedures to clone adult cattle. With the announcement of Dolly, the first ever clone of an adult animal, USDA provided the opportunity for her to work and study cloning procedures in Dr. Ian Wilmut’s laboratory at the Roslin Institute in Scotland for two months in fall 1997. After returning from Scotland, she accepted a position at the UT Department of Animal Science. As a reproductive physiologist, a long-term goal of her research program has and will continue to focus on generating information for eventual development of management strategies to improve reproduction of farm animals and creating alternative methods to alter sex ratio before the time of conception. To this end, she has spent a considerable amount of time determining effects of environmental stressors to reduce female fertility related to direct effects of hyperthermia on the oocyte and early embryo. In vitro production of embryos and cloning procedures are just two of many tools utilized in her laboratory to address basic problems facing animal agriculture. Her program involves both basic and applied research. Dr. Edwards is graduate director and an active member of the graduate faculty. She was most recently provided the opportunity to serve as responsible instructor for the undergraduate reproduction course at UTK and lectures in numerous others.

His primary responsibility includes statewide Extension education in beef cattle with an emphasis on reproductive management. Dr. Anderson is also chairman of the Beef IRM Coordinating Committee, which has been awarded more than $6 million to develop and conduct educational programs like Master Cattleman, Advanced Master Cattleman, Cow College and Master Grazer.

Dr. Richard G. "Dick" Saacke

Professor emeritus, reproductive physiology, Virginia Tech. Dr. Saacke is professor emeritus of reproductive physiology at Virginia Tech, Blacksburg, Va. He is a graduate of Rutgers University and holds advanced degrees from Pennsylvania State University. His work has centered on the structure and function of spermatozoa and ova. Particular areas of research emphasis have included optimization of semen preservation methods and identification of semen traits important to sperm transport in the female, to fertilization, and embryonic development. The general focus of his work has been toward improvement of reproductive efficiency using artificial insemination. Saacke has been recognized for his research, having received the National Association of Animal Breeders Research Award in 1985, the Upjohn Physiology Award from the American Dairy Science Association in 1988 and the 2006 Casida Award from the American Society of Animal Science for training graduate students.

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.

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.
