Professor Phil Hynd

Biography/ Background

Professor Hynd completed his first degree (Bachelor of Rural Science) at the University of New England in Armidale NSW and was awarded First Class Honours and Dux of the year.  He then completed his PhD in Animal Nutrition at The University of Adelaide.  He was appointed the JS Davies Postdoctoral Research Fellow and investigated rumen function and nutrient yield in grazing beef cattle.  On appointment as Lecturer in Animal Nutrition at Adelaide University, he established a research group in sheep nutrition and wool biology.  He was appointed Professor of Animal Production and Head of the Department of Animal Sciences.  He relocated the Department to the Roseworthy Campus and was appointed Director of the Campus.   Under his leadership the Department established the successful Animal Science degree and identified the potential for establishing veterinary sciences on the Campus, a potential which has since been realised.

Teaching Interests

Prof Hynd coordinates the courses Comparative Animal Anatomy and Physiology A and B, and Animal Nutrition and Metabolism.  His teaching philosophy is 'learning by doing'.  Hands-on, animal-based practicals stimulate students to want to find information from all sources (lectures, primary literature, tutorials, academic staff discussions).

Research Interests

Prof Hynd's research interests are at the intersection of nutrition and genetics, namely the impact of nutrients on gene expression, particularly in developing tissues and in disease states.  This field of functional genomics is rapidly evolving now that rapid screening of tens of thousands of genes is possible.  By targeting key windows of development during fetal life, we are able to influence the lifelong health and production of animals.

• epithelial/mesenchymal interactions in developing animal embryos
• nutrient/gene interactions in developing animals (avian and mammalian), and the potential for manipulating fetal development using targeted nutrients
• mucosal hypersensitivity diarrhoea (scouring) in sheep
• postoperative analgesia and wound healing in sheep
• subacute ruminal acidosis in dairy cattle and sheep-

Research Funding

Prof Hynd's research is funded from competitive industry and commonwealth grants.  Australian Wool Innovations Ltd and Cooperative Research Centres (Premium Quality Wool, and the current Sheep CRC) have funded his research over many years.  An ARC grant on Polyamine metabolism and hair growth led to the devlopment of a commercial product for hair growth inhibition.  Direct industry funding for studies of hair growth (Proctor and Gamble Ltd), Alpaca fibre production adn sheep skin analysis is channelled through an established business (Fibrescan).
