Professor Ruminant Health
Faculty of Sciences
Peter Cockcroft is Professor in Ruminant Health at the School of Animal and Veterinary Sciences, University of Adelaide. His current research interests include the transitional ruminant, BVD in sheep and alpacas and improved methods of targeted disease monitoring and surveillance. Teaching interests include: clinical diagnostics, evidence-based veterinary medicine and population medicine. Peter has published 5 veterinary books including: ‘A Handbook of Evidence-based Veterinary Medicine’; ‘Handbook of Clinical Veterinary Research’ and ‘Bovine Medicine’. Peter is an experienced production animal clinician and academic. He is currently Head of the Production Animal Health Department.
Colostrum as a sample type in ELISA tests
Colostrum contains a relatively high concentration of immunoglobulins when compared to serum. This can be used to advantage by increasing the test sensitivity of ELISA tests. My current reaserch has been to explore the diagnostic utility of this sample type accross a range of important diseases in production animals. Our work has examined the improvement of the test sensitivity of the Johne's Disease (Mycobacterium avium partuberculosis) ELISA in cattle. This sample type may also have an application in the diagnosis of Bovine TB (Mycobacterium bovis) in cattle using the new antigen arrays. Our future resaerch will be targeting these diseases in more detail.
Bovine Viral Diarrhoea Virus (BVDv) and reservoir hosts
BVDV is an economically important infection causing disease in cattle worldwide. This virus can infect other species including sheep and alpacas. Our current research is exploring the potential of these species to act as reservoir hosts for cattle and the risk posed by infected cattle to these species.

My current major roles the School's programmes are as the primary tutor and course co-ordinator of the production animal health clinical rotation in the final year of the veterinary programme. I also have teaching responsibilities in other courses in the programes related to production animal health, in particular the teaching of cattle and alpaca medicine.
