Professor Emeritus/Emerita (University) | DVM, MSc
Dr. Ken Leslie was raised on a dairy farm in central Ontario. He graduated from the Ontario Veterinary College in 1974, and developed cattle practice skills in Brampton, Ontario. In 1977, he accepted a clinical faculty position at the University of Guelph. Subsequently, Ken completed his M.Sc. graduate training in dairy cattle reproductive management. Dr. Leslie retired in 2011, after 34 years on faculty in the Department of Population Medicine. His career responsibilities involved teaching, research and extension education of dairy health management programs. Dr. Leslie originated the Dairy Health Management Certificate Program, which has provided detailed training for more than 100 dairy practitioners, and continues to be held each spring as an annual extension education conference. Through all of these efforts, his primary objective has been to foster awareness and interest in the implementation of progressive health management programs for the dairy industry.
Dr. Leslie has established an international reputation for his research and extension in mastitis control, calf health management and dairy cattle well-being. His special interests are udder health and calf management programs, as well as the interactions of dairy cattle behaviour and animal health.
