For almost four decades Professor Hemsworth pioneered and led internationally
acclaimed research on the role of human-animal interactions on the welfare and
productivity of farm livestock.
His research (over 500 publications and 200 peer reviewed papers) has shown how
human characteristics, such as attitudes and behaviour towards farm animals, affect
their fear and acute and chronic stress responses - seriously limiting both farm animal
welfare and productivity. By understanding the influence of human attitudes and
behaviour on animal fear, stress, productivity and welfare, this research underpinned
the development and application of purpose-designed training programmes in the dairy,
pig and poultry industries. These programmes successfully modified key human
characteristics and resulted in improvements in farm animal welfare and productivity.
His research programme was multi-faceted, evolving from studies in laboratories and
farms, then extended to psychological investigation of both the impact of stockperson
attitudes on farm livestock and motivational modification of stockpersons - resulting in
welfare and productivity improvement. Most recently he has extended his work to
human-animal interactions in zoos and domestic settings.
In 1997, Professor Hemsworth jointly established the Animal Welfare Science Centre
(AWSC) with the University of Melbourne, Monash University and the Department of Natural Resources and Environment (Victoria). As Director (a post he held until 2017),
he led it to become the pre-eminent such Centre in Australia and for it to deservedly
enjoy a reputation internationally as an innovative major contributor to animal welfare
science developments involving the key disciplines of animal behaviour, psychology,
stress physiology and veterinary medicine.
The Centre's influence on animal welfare thinking under Professor Hemsworth’s
leadership and active involvement in supervision has been widely spread by its 45
postgraduate students who successfully completed PhD, Masters and Honours
degrees.
