Some of his regional and state-wide Extension programs have included Integrated Toxic Plant Management, Cattle Artificial Insemination and Pregnancy Determination Schools, Total Resource Management, and Beef Quality Assurance. Much of his applied research has focused on range bull and ram fertility, range nutrition, and animal behavior.


Dr. Derek Bailey is a Professor of Range Science and has been at New Mexico State University since 2005. He teaches courses in livestock behavior and welfare, advanced rangeland management and a graduate course in rangeland research methods. In addition to teaching and research responsibilities at NMSU, he is the Director of the Chihuahuan Desert Rangeland Research Center. Derek has over 35 refereed journal publications and has received over one million dollars in extra-mural funding. Prior to coming to NMSU, Derek worked as an assistant and associate professor at Montana State University for nine years, a range management consultant in Nevada for 5 years, a research scientist in Oklahoma for two years, and an extension agent in Arizona for a year. Derek received his PhD and in Range Science at Colorado State University and his MS and BS degrees in Animal Science at Colorado State. After growing up on a cattle ranch in southern Colorado, Derek has maintained his interest in rangeland livestock production. His research has focused on the mechanisms of grazing distribution and animal behavior. Derek's approach is to meld livestock behavior, animal learning, animal nutrition, animal breeding, low-stress stockmanship, grazing ecology and vegetation restoration into practical approaches to resolve management issues on rangelands.
