Current research programs within the group focus on the absorption of nutrients from the gastrointestinal tract, regulation of metabolism in the liver and manipulation of growth, lactation and body composition of ruminant animals. Studies employ a wide variety of in vivo and in vitro techniques including surgically prepared animals with indwelling catheters and blood flow probes, perfusion of isolated organs, isolated cells and sub-cellular particles. Field trials on feed conversion, growth and lactation are also conducted to evaluate application of findings. Bacterial virulence, bacterial mineral metabolism and factors that contribute to the presence and multiplication of pathogenic and spoilage organisms which affect agricultural industries. Microbiological research in the Department is directed towards the elucidation of mechanisms of pathogenicity, colonization, spoilage and resistance to anti-microbial agents.
Parasites cause major diseases of man and animals throughout the world.
The control of these diseases requires research into new drugs, vaccines and diagnostics. This group's research is aimed at developing control measures based on biochemical, immunological and molecular research. Expenditure on phosphorus fertiliser is one of the major costs in maintaining the productivity of cropping and legume-based pastures in temperate Australia. There is increasing awareness that the low rate of adoption of productive and profitable grazing systems has limited gains in productivity in the high rainfall zone. The aims of this research group are to develop methods to empower farmers to adopt productive pasture technology on farms.
