Dairy Farmers of Ontario Chair in Dairy Cattle Health | Professor | DVM, PhD, MSc
Dr. Kelton is a veterinary epidemiologist and the Dairy Farmers of Ontario Dairy Cattle Health Research Chair in the Department of Population Medicine. He is a member of Scientific Committee of the Canadian Bovine Mastitis and Milk Quality Research Network and the Canadian Representative to the International Dairy Federation Standing Committee on Animal Health and Welfare. He teaches in the undergraduate, graduate and professional curriculum and is a member of several local, provincial and national working groups dealing with dairy cattle health and animal disease surveillance. His research interests include infectious and metabolic diseases of dairy cattle, including particular interest in Johne’s Disease, bovine mastitis and bovine lameness.
My research interests include infectious and metabolic diseases of dairy cattle, including particular interest in Johne’s Disease, bovine mastitis and bovine lameness. Over the last 25 years I have worked closely with dairy producers, dairy producer organizations and veterinary practitioners in developing field-based research projects that address practical issues of concern to the Canadian dairy industry. I am particularly proud of my long-standing research partnership with Canwest DHI and work that we have done to validate milk based tests for Canadian dairy farmers.
Current Graduate Students
I teach in the DVM and graduate programs at the University of Guelph. My DVM program teaching focuses on aspects of evidence-based veterinary medicine, infectious disease control and dairy health management.
