Methane and nitrous oxide in agro-ecological systems: novel technologies and understandings to improve ecosystem management. Methane and nitrous oxide are critical greenhouse gases but globally we lack ecosystem scale analyses of the balance of emissions, including animal emissions, and soil oxidation. This project will quantify this balance for a range of agro-ecosystems, and explore and develop opportunities for improving soil-based Greenhouse Gas (GHG) mitigation measures.
Development of a new diet to improve insulin sensitivity and manage weight in healthy cats. This project will determine if a low carbohydrate, moderate fat, high protein diet improves insulin sensitivity and reduces weight gain in cats compared to a typical high-carbohydrate grocery line diet. It will identify risk factors for weight gain such as increased fasting insulin concentration and will also determine which simple assessment of insulin sensitivity best correlates with insulin sensitivity ....Development of a new diet to improve insulin sensitivity and manage weight in healthy cats. This project will determine if a low carbohydrate, moderate fat, high protein diet improves insulin sensitivity and reduces weight gain in cats compared to a typical high-carbohydrate grocery line diet. It will identify risk factors for weight gain such as increased fasting insulin concentration and will also determine which simple assessment of insulin sensitivity best correlates with insulin sensitivity measured by a gold standard. This project should lead to the formulation of a diet designed to improve insulin sensitivity and minimize weight gain in cats, and allow for earlier identification of cats at risk of obesity.Read moreRead less
Early life nutrition to improve feed efficiency in commercial dairy goats. This project aims to improve the productivity and welfare and reduce resource waste in commercial dairy goat kids. The Australian dairy goat industry is expanding (~20% per annum) yet there is little research to overcome hurdles to improving milk and meat production. There is also increased societal pressure to improve sustainability, reduce waste and maintain animal welfare. By investigating nutritional methods to improv ....Early life nutrition to improve feed efficiency in commercial dairy goats. This project aims to improve the productivity and welfare and reduce resource waste in commercial dairy goat kids. The Australian dairy goat industry is expanding (~20% per annum) yet there is little research to overcome hurdles to improving milk and meat production. There is also increased societal pressure to improve sustainability, reduce waste and maintain animal welfare. By investigating nutritional methods to improve productivity of male (for meat) and female (for milk) kids, this project will generate new knowledge relevant to Australian and international goat production systems. This project will assist goat producers to make decisions that maximise animal productivity with flow on benefits to manufacturers of goat products. Read moreRead less
Solving smoke taint: Overcoming the impacts of vineyard exposure to smoke. Vineyard exposure to bushfire smoke can taint grapes, causing significant revenue losses where smoky, ashy characters render wine unsaleable. Smoke taint therefore remains an ongoing threat to the viability of the wine industry. This project aims to safeguard grape and wine quality by building the wine industry’s capacity to predict, mitigate and respond to risk associated with vineyard smoke exposure. Expected outcomes i ....Solving smoke taint: Overcoming the impacts of vineyard exposure to smoke. Vineyard exposure to bushfire smoke can taint grapes, causing significant revenue losses where smoky, ashy characters render wine unsaleable. Smoke taint therefore remains an ongoing threat to the viability of the wine industry. This project aims to safeguard grape and wine quality by building the wine industry’s capacity to predict, mitigate and respond to risk associated with vineyard smoke exposure. Expected outcomes include establishing the mechanism by which smoke compounds are taken up by grapes and the factors that influence their sensory impact on wine. The development of innovative and interdisciplinary strategies for detecting and alleviating smoke taint will deliver important economic benefit to the Australian wine sector.Read moreRead less
How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of natu ....How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of naturally (through maternal conditioning) boosting the natural appetite and the capacity to digest in piglets early in life. The anticipated outcome is that the new peri-natal program will result in minimal bacterial proliferation and diarrhoea thus, negating the need for in-feed antimicrobials in piglets.

This proposal aims to use an innovative approach to address an urgent issue raised by the end users of an Australian-owned poultry vaccine with an extensive global market. Recently multiple mutations have been detected in the vaccine re-isolated from vaccinated birds in the field around the world. We will apply a combination of a novel technique for targeted mutagenesis, genome sequencing, and animal experimentations, to address the significance of these mutations. Results will improve our understanding of the basis of attenuation of the vaccine, its mechanism of action, and provide commercial confidence in the safety of the vaccine, which is needed to support Australian Universities and Businesses, and the global poultry industry.Read moreRead less
Characterisation and Mitigation of Caustic Cracking: A Safety and Maintenance Concern in Alumina and Pulp-and-Paper Processing. Extraction of alumina from mineral bauxite (Bayer process) and pulp-and-paper processing (Kraft process) are major industries in Australia. Cracking of reaction vessels, digesters, cleaning tanks and pipework are major concern for plant integrity, occupational health, safety and environment. Caustic cracking is often the first suspect when a failure occurs. The propose ....Characterisation and Mitigation of Caustic Cracking: A Safety and Maintenance Concern in Alumina and Pulp-and-Paper Processing. Extraction of alumina from mineral bauxite (Bayer process) and pulp-and-paper processing (Kraft process) are major industries in Australia. Cracking of reaction vessels, digesters, cleaning tanks and pipework are major concern for plant integrity, occupational health, safety and environment. Caustic cracking is often the first suspect when a failure occurs. The proposed program will investigate the role of critical impurities and additives, temperature and stress fluctuations in caustic cracking of mild steel and their weldments (known to be most susceptible). This project will also develop an intellectual and infrastructural base that will also be a vital resource for several Australian industries where such cracking is a major concern.Read moreRead less
Biological control of grapevine scales. Wine grapes can be grown with a minimum of pesticide and fungicide applications in some regions, but biological control is still required to maintain populations of major pests. This project is concerned with grapevine and frosted scales, which are common pests of grapevines. The distribution and identity of different grapevine scales, and their main parasitoids, in the various grape growing regions of Australia will be determined by initial surveys. Exper ....Biological control of grapevine scales.
