Expertise Topics

Professor Bryden’s research interests principally concern animal nutrition and toxicology, plant associated toxins, mycotoxins and fungal ecology. In particular;
  • The objective of his research in nutrition (pigs, poultry and horses) is to produce strategies that will (i) balance the key nutrients (energy, amino acids) absorbed and (ii) alter nutrient availability and override metabolic processes determining tissue deposition rates, especially that of protein and fat including the alleviation aspects of metabolic disease in poultry and horses.
  • Nutritional, physiological and immunological aspects of stress in laying hens in different housing systems, feedlot cattle and horse transport.
  • The occurrence of mycotoxins, their effects in different animal species, including man and the implications for food safety of these toxins in the food chain.
  • The relationship of the maternal environment to the growth and development of the equine foetus, in particular the ingestion of caterpillars and foetal loss, and maternal insulin resistance and bone development of the foetus.
  • Application of the pig as a biomedical model for the study of gastrointestinal physiology.

Research Projects

During his research career, Professor Bryden has attracted some $16 Million in research income from major research funding bodies within Australia.

Professor Bryden is the Foundation Chair in Animal Science at the University of Queensland. He was Head of the School of Animal Studies at the University of Queensland from 2002 to 2007 and prior to that appointment was Pro-Dean of the Faculty of Veterinary Science at the University of Sydney, where he was also Director of the Poultry Research Foundation. His research interests include nutrition of monogastric animals and nutritional toxicology of all domestic species and he is a registered Animal Nutritionist. He lectures in a range of subjects to both animal science and veterinary science students and has advised some 50 research higher degree students. In 2003 he was awarded the Centenary Medal for his contributions to science and education, and in 2005 he co-chaired the Gordon Research Conference on Mycotoxins and Phycotoxins. He is currently a member of the WHO Expert Panel on Food Safety, President of the Australasian Equine Science Society and Editor-in-Chief of Animal Production Science.
