Professor Cameron Clark
I am enabling a step-change in livestock productivity and welfare both in Australia and internationally through my novel, collaborative research. My research is changing the global focus of farming towards the individual production animal to improve efficiency and welfare by revealing the value of technology, data and associated advanced precision livestock systems. I plan to expand on this highly innovative research to link the individual production animal and farm practice with the needs of the market and in so doing, add significant value to the food produced in systems that exceed the welfare demands of society. I have a particular interest in the diversity in heat resilience within livestock species.
  • Turning existing, and new sensor derived, farm data into information that farmers can use to improve profit, lifestyle and animal welfare
  • The use of sensor data and livestock behaviour to detect reduced health earlier than conventional methods
  • The use of sensor data and livestock behaviour to improve livestock climate resilience

I co-ordinate and teach into AVBS1002: Concepts of Animal Management. A fantastic broad Unit introducing animal production systems and our environment with practicals at our Camden Campus.
