Gastrointestinal parasites are the major cause of production losses in the Australian sheep and wool industries. Drug treatment is predominantly used to control infections but drug resistance has reached critical levels and is threatening the viability of sheep production in many rural areas. In collaboration with an international Animal Health company, we aim to develop vaccines against these parasites and provide a clean, non-toxic alternative to drug treatment. The groundbreaking research involved in this project will also keep Australian animal scientists at the forefront of vaccine research and increase their capacity to attract further support from Industry.Read moreRead less

The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans. This project will investigate the sheep lousicidal and anthelmintic activity of a number of plants, and identify and chemically characterize the active constituents. This research will lead to the production of more environmentally friendly pest control methods and overcome problems of insecticidal resistance currently facing the industry.Read moreRead less
The Properties and Processing Performance of Ultrasonically Cleaned Wool Fibres. Australian wool production is a $2.5 billion export industry, and about 70% of Australian wool is exported to China for further processing. Scouring or wool cleaning is the first critical step in the processing chain, which has come under increasing pressure to reduce water and energy consumption and effluent discharge. Assisting leading wool processors in the research and development of the latest wool processing t ....The Properties and Processing Performance of Ultrasonically Cleaned Wool Fibres.

Investigation of the immunological properties of a novel adjuvant in sheep. The induction of strong immune responses without side effects is a highly desirable goal in vaccine R&D. The recently developed adjuvant DCtag utilises unique properties of dendritic cells to boost both cellular and humoral immune responses without tissue damage. This project will identify the mechanisms of immune induction of DCtag using unique properties of our sheep cannulation model. This will allow further optimisat ....Investigation of the immunological properties of a novel adjuvant in sheep.

The recently developed adjuvant DCtag utilises unique properties of dendritic cells to boost both cellular and humoral immune responses without tissue damage. This project will identify the mechanisms of immune induction of DCtag using unique properties of our sheep cannulation model. This will allow further optimisation of DCtag adjuvanticity in sheep, which will then be applied to the delivery of a prototype peptide based vaccine against foot and mouth disease virus, a veterinary disease of global importance, hereby increasing Australia's leadership in biotechnology.Read moreRead less
Novel semio-chemical approach to control the Australian Sheep Blowfly . The Australian Federal Government through the 'Smart Farming' initiative highlights the need for improved multidisciplinary measures in order to remain at the global forefront of the invention and adoption of technology.

The Australian Federal Government through the 'Smart Farming' initiative highlights the need for improved multidisciplinary measures in order to remain at the global forefront of the invention and adoption of technology. This multidisciplinary project (entomology, biotechnology, analytical chemistry and genomics) will rapidly inform the management of fly strike on an important Australian resource merino sheep. This will build the key biochemical data in order to develop a novel fly lure technology (at scale) to be used on farm delivering national benefit through improved animal welfare and safety considerations for producers, and will establish the best approach to disseminate this scientific information to stakeholders such as farmers.Read moreRead less
Application of DNA vaccination to the control of gastrointestinal nematodes in livestock. Gastrointestinal nematode parasites inflict great losses in sheep and cattle and reliance on anthelmintic drugs for their control is problematic. Vaccination would provide a better alternative but has been difficult to achieve.

Gastrointestinal nematode parasites inflict great losses in sheep and cattle and reliance on anthelmintic drugs for their control is problematic. Vaccination would provide a better alternative but has been difficult to achieve. This proposal aims to apply novel DNA vaccination strategies to the development of parasite vaccines through optimisation of DNA delivery, development of new vaccination vectors and modulation of immune responses by co-delivery of cytokine genes. The results of these studies will not only add a new approach to vaccine development against gastrointestinal parasites but will also contribute to our knowledge of DNA vaccination in large animals.Read moreRead less
Topical and cryoanaesthesia for livestock husbandry. The livestock industries contribute $15billion annually to Australia's economy, playing a vital role in rural communities. However we must respond to changing demands of our customers, by complementing our competitive disease-free advantage with welfare-conscious production systems.

The livestock industries contribute $15billion annually to Australia's economy, playing a vital role in rural communities. However we must respond to changing demands of our customers, by complementing our competitive disease-free advantage with welfare-conscious production systems. This project will address the threat of growing international demands for improved animal welfare in farming. We will provide research and technical solutions, providing pain mangement products for on-farm use that will reduce animal suffering during routine husbandry interventions. The project offers significant benefits for producers by protecting their industries against the threats of a welfare embargo on our livestock products. Read moreRead less
Application of in vivo electroporation to DNA immunisation. The in vivo delivery of plasmid DNA induces immune responses to the encoded protein vaccine. In large animals including humans, DNA vaccination needs to be further improved before becoming a commercial reality, at least partially due to the very low levels of expression in vivo. In vivo electroporation has proven to be an effective way to enhance the level of protein expression and increase DNA vaccine efficacy. We combine enhanced in ....Application of in vivo electroporation to DNA immunisation. The in vivo delivery of plasmid DNA induces immune responses to the encoded protein vaccine. In large animals including humans, DNA vaccination needs to be further improved before becoming a commercial reality, at least partially due to the very low levels of expression in vivo. In vivo electroporation has proven to be an effective way to enhance the level of protein expression and increase DNA vaccine efficacy. We combine enhanced in vivo expression using electroporation with the co-delivery of plasmids encoding cytokines to enhance and modulate DNA vaccine in sheep. We will apply our findings to bovine viral diarrhoea virus (BVDV), both as an animal model for humans and as an economically important diseases of livestock.Read moreRead less
Engineering safer pastures for livestock. This project aims to develop subterranean clover with elevated condensed tannins in leaves. This important pasture legume is currently a bloat risk for cattle and sheep due to low condensed tannins and high soluble proteins. Bloat is a health issue that costs the Australian and New Zealand livestock industries over $200 million per annum. Condensed tannins can reduce bloat, decrease methane production and improve efficiency of production. A novel approac ....Engineering safer pastures for livestock. This project aims to develop subterranean clover with elevated condensed tannins in leaves. This important pasture legume is currently a bloat risk for cattle and sheep due to low condensed tannins and high soluble proteins. Bloat is a health issue that costs the Australian and New Zealand livestock industries over $200 million per annum. Condensed tannins can reduce bloat, decrease methane production and improve efficiency of production. A novel approach using CRISPR and other innovative molecular techniques will generate breeding lines high in condensed tannins and deliver knowledge applicable to other pasture legumes. Expected outcomes for livestock producers include improved animal welfare, reduced carbon emissions and enhanced profits.Read moreRead less
