Duane Kraemer
Retired Professor Department of Veterinary Physiology & PharmacologyResearch and Scholarly Interests
Most of my research career has been dedicated to adaptation of embryo transfer and related technologies (such as in-vitro fertilization, gamete and embryo cryopreservation and cloning) for selective breeding and conservation in a variety of animal species including food animals, companion animals, biomedical models and wildlife. For example, my colleagues, staff students and I were the first to successfully perfom embryo transfer in cats, dogs, deer, antelope and primates; and the first to clone cats and deer.
While working on my Ph.D. in the Animal Science department, I taught two undergraduate courses, "Horse Management and Training" and, "Methods of Livestock Selection". After completion of the D.V.M. and Ph.D. degrees in 1966, I moved to the Southwest Foundation of Research and Education for nine years during which I did very little teaching, although I did mentor several technicians. In 1975 I returned to Texas A&M with a 50% appointment the Department of Veterinary Physiology and Pharmacology and 50% in the Department of Animal Science. I taught the Reproductive Physiology portion of the Veterinary Physiology course in the professional curriculum and the graduate course, "Gamete and Embryo Physiology". I served as Chair of 31 M.S., 14 M.Agr. and 26 Ph.D. graduate committees; and Co-chair of 2 M.S. and 9 Ph.D. graduate committees; and a member of 92 graduate committees. During the past 20 years, I have taught approximately 125 contact hours in veterinary professional courses, 113 contact hours in graduate courses and 123 contact hours in undergraduate courses.
Service activities include 7 years as Associate Dean for Research and Graduate programs in the College of Veterinary Medicine and 7 years as Chair of the University Laboratory Animal Care Committee.
I can no longer accept graduate or post doctoral students.

My lab is interested in the development and application of assisted reproductive technologies as a means to help preserve endangered species. Currently, there are more then one thousand species world wide listed as being endangered while in the United States alone, 496 species of animals are listed as threatened or endangered. My research program is dedicated to better understanding the unique reproductive biology of different mammalian species and developing the technological capability to assist with their survival as a species when threatened with extinction. We also use these technologies for the preservation and production of animal models for biomedical research.

Dr. Kraemer, a student of Dr. Berry’s, performed the world’s first embryo transfers in a variety of animal species, including non-human primates. Based upon Dr. Kraemer’s pioneering studies, more than 1 million cattle embryos are transferred each year and his techniques formed the basis for modern practices in human and conservation medicine.
Dr. Kraemer produced the very first commercial embryo transfer in cattle (1971), and primates (late 1970s) and was instrumental in launching the field of commercial embryo transfer.
Dr. Kraemer provides guest lecturers in undergraduate, graduate and professional courses covering facets of reproductive biology.
