Current Funding

Current and recent Research Funding to JCU is shown by funding source and project.

CRC for Developing Northern Australia Scheme - Projects

Improving the productivity of the Northern Australian livestock sector with the establishment of new legumes varieties

Indicative Funding: $360,000 over 3 years (administered by Agrimix Pty Ltd)
Summary: Pasture legumes are quality feed and have benefits for livestock and the environment but few sown legumes are adapted to the vast clay soil regions of the north. JCU has 5 new varieties specifically developed for this region. The project aims is to: ? Evaluate establishment techniques for these new legumes ? Conduct grazing, pen, plot and soil trials evaluating new varieties ? Demonstrate the benefits of legumes in terms of enhance livestock productivity ? Undertake climate risk analysis ? Engage students with a research focus on nutrition, soils and livestock productivity Uptake of legume technology will result in significant economic, environmental & social benefits
Investigators: Chris Gardiner, Aduli Malau-Aduli, Glen Walker, Ed Charmley and Zed Rengel (College of Public Health, Medical & Vet Sciences, Commonwealth Scientific & Industrial Research Organisation and The University of Western Australia)
Keywords: Desmanthus Legumes; Tropical Pasture; Livestock productivity; Mimosaceae

Tattykeel Research Pty Ltd - Research Grant

Genetics and nutrigenomics of intramuscular fat, fat melting point and meat eating quality in Australian White Lambs

Indicative Funding: $100,000 over 2 years
Summary: The over-arching aim of this research project is to enhance the sustainable production of Australian White (AW) sheep meat with superior eating qualities and healthier nutritional composition without compromising animal health, performance and welfare. Specific research objectives include: (1) Nutrigenomics analysis of intramuscular fat content, fat melting point, fatty acid composition and marbling gene expressions in grazing and supplemented sheep. (2) Sensory evaluation of meat eating quality of AW lamb in city restaurants (3) Next generation sequencing and creating of a genomic DNA bank of the AW lamb with a unique breed signature.
