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. Dr. Bertrand is the leader of the beef cattle genetics research group within the Animal and Dairy Science Department. Currently, this group provides genetic values in the form of expected progeny differences for 10 beef breed associations located in Canada and the U.S. Undergraduate curriculum responsibilities include teaching two courses: Introductory Animal and Dairy Science and Introduction to the Genetics of Livestock Improvement. Dr. Bertrand is active in undergraduate advising and in graduate advising at both the M.S. and Ph.D levels.
