Jack Whittier

Dr. Jack C. Whittier is an Extension Beef Specialist and Associate Professor at Colorado State University. He received a Bachelor’s Degree in 1979 and a Master’s Degree in 1981 from Utah State University, and a PhD from the University of Nebraska in 1985. He then joined the faculty at the University of Missouri as Extension Cow-Calf Specialist where he worked for 9 years. In February 1995 Dr. Whittier joined the faculty in Animal Science at Colorado State University.

During his tenure at both the University of Missouri and Colorado State University, he has held joint appointments with extension and research. This joint assignment has allowed him to focus both research and educational efforts to meet the needs of cattle producers. Working directly with producers through extension programs has enabled him to identify research needs that were then the focus of his research program. Conversely, by being active in applied research areas related to beef cattle nutrition and reproductive management he has been able to present current, local research information to producers. Being directly involved with graduate students has also enabled his students to get first hand experience in extension education. Much of his work has dealt with reducing the costs associated with producing beef by improved use of forage management. He has also focused on improving reproductive output through proper heifer development, estrous synchronization and management of the cow herd.
