About Me

Dr. Dale ZoBell conducts research on beef cattle with emphasis on growing and finishing beef cattle in the feedlot and on intensively managed irrigated pastures and forages. He collaborates with other agencies and industry partners in an effort to make Utah beef producers more competitive in a world economy. As a subject area specialist programs are developed that focus on beef production.

Dr. ZoBell's extension programs include the Utah Master Beef Management program, Arizona/Utah Range and Livestock Workshop, Utah Beef Field Day, numerous Extension fact sheets, bulletins and popular press articles, Intermountain Beef 3910 Workshop and a resource for Utah Counties.

His research funding comes primarily from the Utah Agricultural Experiment Station as well as industry and the USDA.

In 1977, Dale ZoBell received his B.S. in animal Science at Utah State University then went on and completed a M.S. in Animal Science at Oregon State University. In 1997 Dr. ZoBell received his PhD from Utah State University in ruminant nutrition after a number of years as an Extension Beef Specialist with Alberta Agriculture Food and Rural Development in Canada. In 1998 he returned to Utah State University as Extension Beef Specialist, which is his primary role. Dr. ZoBell also conducts research relative to applied beef cattle production. In addition, Dr. ZoBell serves as Associate Department Head in the Animal, Dairy and Veterinary Sciences Department and became a Full Professor in 2007. Over 35 years in Extension and research in the United States and Canada. Integrated and applied approach, recognizing the importance of the natural resource and economic considerations. Dr. ZoBell is a capable and effective communicator, administrator, facilitator, team-leader, collaborator and researcher. Authored or co-authored 75 research-related papers, over 240 Extension articles, publications, newsletters, and popular press, and he has spoken at over 340 conferences, seminars and field days. Through 2013 he has generated or assisted in raising $2.4 million in grants and funding at Utah State University.
