J. Keith Bertrand

Department Head and Professor
  • Animal & Dairy Science
Shipping Address:
Athens, CAES Campus

B.S., University of Florida
M.S., Iowa State University
Ph.D., Iowa State University


Description of Research and Teaching Interests

The main thrust of Dr. Bertrand’s research program deals with the development, improvement, and implementation of genetic evaluation models for the analysis of large sets of livestock field data with the ultimate goal of predicting breeding values for economically important traits. Live animal research projects are also conducted to test the efficacy of predicted genetic values under real world conditions. He teaches an undergraduate course titled “Introduction to the Genetics of Livestock Improvement” and is involved in advising and mentoring undergraduate and graduate students. Dr. Bertrand is also the Head of the Animal and Dairy Science Department (ADS) and provides administrative oversight of ADS faculty and staff, oversight of the ADS budget and oversight of ADS extension, instruction and research programs on the Athens and Tifton campuses, and the ADS personnel and programs based at the Northwest Georgia Research and Education Center.
