Overview
Background
Professor Alan Tilbrook is nationally and internationally recognised for leading scientific research in animal science and biomedical science (endocrinology, neuroendocrinology, behaviour, stress, and reproduction). He is a global leader in animal welfare science. Professor Tilbrook has an outstanding balanced portfolio in leadership, strategic planning, research, academia, education and government. He is Professor of Animal Welfare in the School of Veterinary Science and has an affiliate appointment in the Centre for Animal Science, Queensland Alliance for Agriculture and Food Innovation at The University of Queensland. Professor Tilbrook is one of three expert members of a Strategy Advisory Group to provide expert strategic advice to the Department of Agriculture, Fisheries and Forestry to assist the development of the renewed Australian Animal Welfare Strategy. He is Chair and Research Champion of the National Primary Industries Animal Welfare Research, Development and Extension Strategy, represents Universities Australia on the Board of the Australian and New Zealand Council for the Care of Animals in Research and Teaching, represents The University of Queensland on the World Organisation for Animal Health and is a member of the Australian Government’s Live Export Animal Welfare Advisory Group. Professor Tilbrook established The Animal Welfare Collaborative, a university-facilitated network of individuals, companies, and organisations working together to make evidence-based improvements in animal welfare. This was a collaborative venture with The University of Newcastle, The University of Western Australia and The University of Adelaide. He was a founder, Deputy Director and Co-Director of the Animal Welfare Science Centre, was the Research Chief of Livestock and Farming Systems at the South Australian Research and Development Institute and was Deputy Head of the Department of Physiology at Monash University. He has held numerous national and local leadership roles. Professor Tilbrook's research is conceptually driven with a multidisciplinary and integrative approach. He has developed cutting edge research programs across a range of species including sheep, pigs, poultry, cattle, goats, rodents, horses, buffalo and humans. Professor Tilbrook places a huge emphasis on collaboration, training and professional development.

Identification of Biomarkers to Assess Animal Welfare
We are seeking to identify biological markers (biomarkers) of animal experiences. The brain processes the experiences of animals. These experiences determine the state of welfare of an animal at any given time. We aim to take peripheral measures of biomarkers that are indicative of brain processing of experiences.
-
Importance of human and maternal contact on stress resilience in pigs
We are investigating the impact of human and maternal contact in early life on stress resilience in pigs later in life. The research considers the importance of this early human and maternal contact in affecting welfare, growth and meat quality of pigs.
-
Elimination of the need for tail removal in pigs
This large-scale research investigates the reasons for tail biting in pigs with the view to developing strategies to eliminate tail biting without the need to remove tails from piglets. The research has both experimental and epidemiological components.
-
Interpreting the welfare of animals exported live by ship
This is project is called “Interpreting Animal Welfare", and is collaborative research led by The University of Western Australia. The project seeks to create an integrated framework capable of assessing, interpreting and aggregating intricate animal welfare data collected during export voyages to give an overall evaluation of animal welfare status.
-
Effects of floor space on the welfare of pigs
It is known that restricting space in breeding female pigs can lead to aggression, injuries and sustained physiological stress. Sustained stress in pigs can compromise the health, efficiency of growth and meat quality. The effects of space allowance on the welfare, growth and productivity of finisher pigs have not been well researched. The focus of this research is to determine the effects of different amounts of floor space on the welfare, growth and production parameters of finisher pigs.

Health and welfare of free-range buffalo in the northern Australia
This project is focussed on understanding and improving the health and welfare of harvested buffalo throughout the supply chain. The research is on free-range buffalo from Arnhem Land, Northern Territory. The work is highly collaborative, multidisciplinary and multi-faceted.
Research impacts
Our research on biomarkers of animal welfare is world leading and novel. We have identified biological markers of brain function in animals which will inform how the brain processes experiences and thereby animal welfare. While this research is emerging and is still in the discovery phase, the objective is for the non-invasive measurement of these biomarkers to be applied in the livestock industries.
We have demonstrated the impact of human and maternal contact in early life on stress resilience in pigs later in life, affecting welfare, growth and meat quality. This presents the opportunity to develop strategies to maximise positive human contact and improve maternal contact in the pork industry.
We also pioneered research to measure steroids in the wool of sheep that has resulted in publications and on-farm assessment of stress, wool quality and epigenetic influences on parameters of stress and reproduction in sheep.
