Emeritus Professor Norm Williamson

Emeritus Professor of Veterinary Medicine

School of Veterinary Science

Norm graduated from Melbourne University in 1968, stayed on as a tutor in the farm services clinic and did a Masters' degree in cattle reproductive health management. He gained a MACVSc (MANZCVS) in the medicine and preventive medicine of dairy cattle in 1977. He joined the Department of Agriculture, Victoria in 1973 and oversaw a large herd health project while still stationed at the Vet School in Werribee. From 1980 to 1989 he was an Associate, then Full Professor of Theriogenology and Herd Health at the University of Minnesota in the USA. While there he gained a Diploma of the American College of Theriogenologists in 1984. He moved to New Zealand as Professor of Veterinary Medicine and Head of the Department of Veterinary Clinical Sciences in 1989. In 1998 he was appointed as Head of Undergraduate Teaching in the newly formed Institute of Veterinary, Animal and Biomedical Sciences, then in 2000 he was appointed as the Programme Director, Veterinary Science in the College of Science and stepped down in June 2011. Norm's teaching and research interests are in cattle health and management. Particular interests are in cattle reproduction, mastitis, heifer rearing, neosporosis and herd health records. Norm has authored or co-authored over 75 refereed publications and over 200 other publications and presentations. He also has a great interest in veterinary education of all types.

Research Expertise

Research Interests

My research is into factors limiting the health, welfare and productivity of ruminants, particularly dairy cattle. Throughout my career my approach has been to identify factors most limiting the health and productivity of dairy cattle and to undertake research to remove or overcome them. Mastitis remains the most prevalent infectious disease of dairy cattle and still limits the health, welfare and productivity of dairy cows. It is a focus of my research efforts. Reproductive inefficiency has been identified by DairyNZ as a priority area for research and development and this has been a continuing area of research for me. This is addressed through continuing research on fertility monitoring, oestrus detection methods and also on Neospora caninum abortion. The latter severely limits herd reproductive performance in herds suffering outbreaks and chronically reduces reproductive performance in endemically infected herds. I have consistently used computer based technology to collect and manipulate data to provide farmers with information that is useful to them in making management decisions for cows and herds.
