WALRC: Western Australian Livestock Reseach Council




Mandy currently manages the Information and Evaluation project for Sheep Industries at the Department of Primary Industries and Regional Development. Her research roles have been in sheep nutrition and reproduction, specialising in delivery of training in sheep reproduction

management. Product and tool development for sheep producers is a particular focus and passion.

David Beatty &

Irene Sobotta


WALRC is an initiative of MLA and as the primary funder of WALRC, MLA holds two positions on the council. David Beatty is Program Manager – Value Chain Research, Development and Adoption, while Irene Sobotta is MLA’s Program Manager for Consultation. Both make a vibrant contribution to the efficacy of WALRC.



Hayley is a principal research scientist, leading the CSIRO mixed farming systems team in WA. She has expertise in ruminant nutrition, forage improvement and integrated crop/livestock systems in dry and saline areas. Her team primarily conduct research in southern Australia but also have projects in Afghanistan, Pakistan, Myanmar and Tibet. Recent outputs include near infra-red spectrometry calibrations for rapid and inexpensive prediction of nutritional value of plants in the southern feedbase.  Hayley led the development and commercialization of AnamekaTM saltbush - a cultivar with improved feeding value to sheep and cattle.


Curtin University

Sue specialises in animal nutrition and animal production systems, with more than 30 years experience in CSIRO, state DPI's in Australia, university lecturing in Papua New Guinea and Australia and private industry in both Australia and Papua New Guinea. In private industry she has worked as a nutritional consultant to the poultry industry, designed and commissioned 4 feed analysis laboratories (ruminant and monogastric) and implemented quality control management systems in 2 feed mills. Key areas of research include studies on the effects of  tropical pastures that exhibit toxicity mechanisms, such as signal grass (Brachiaria decumbens), on the productivity of Brahman cattle.  At Curtin, Sue coordinates the teaching of all animal science/production units at undergraduate and postgraduate levels.


University of Western Australia

Phil is an animal scientist. His research interests are in ruminant production systems and finding ways to balance productivity with biodiversity in extensive grazing systems. All of his research is driven by the need for ‘Clean, Green and Ethical’ livestock production and the importance of optimising the interaction between genotype, environment and management. His most recent research has been focused on mitigating methane emissions from sheep and cattle through manipulating the feed base, exploring the antimethanogenic properties of plant secondary compounds in Australian native plants, and genetic selection.


Murdoch University

Caroline’s role at Murdoch University is centered around Biochemistry and Nutrition and the Centre for Animal Production Research within the School of Veterinary and Life Sciences. She is a Murdoch University graduate in veterinary science and worked in private veterinary practices in Western Australia and United Kingdom after graduation. Her research career has followed a diverse range of interests in the fields of nutrition, parasitology and animal production, and she brings this passion for

veterinary science to her role teaching both undergraduate and post-graduate students in the veterinary science and animal science programmes,

with her main teaching area being animal nutrition.
