PhD, Iowa State University
Ruminant Nutritional Immunology, and Member of AVRI Council
Administrative Involvement: Faculty Animal Policy and Welfare Committee
Dr. Ametaj received his doctorate degree in nutritional immunology from Iowa State University and did three postdoctoral trainings at Iowa State University, Purdue University, and Cornell University before joining University of Alberta in 2004. Dr. Ametaj’s research interest is in the area of nutritional immunology. His long-term goals are to study the relationship between nutrition and immune responses and their contribution in development of production diseases in ruminant animals as well as in developing new strategies to curb down the high incidence of transition diseases in dairy cattle. Dr. Ametaj’s research areas include: 1) studying the etiology and pathogenesis of transmissible spongiform encephalopathies; 2) determining dairy cattle metabolome in four major fluids (milk, plasma, urine, and rumen fluid), 2) developing a new vaccine for prevention of transition cow diseases, 3) using probiotics to prevent uterine infections and improve reproductive and productive performance of dairy cows; 4) studying cow’s health during transitioning from the conventional into the organic system of management; and 5) developing new cereal grain processing technologies to improve health and productivity of ruminant animals.
