Summary
Improving poultry health and performance through microbiota manipulations. The project aims to develop methods to modulate microbiota to improve poultry health and productivity and reduce the need for antibiotics. Probiotic administration is currently the only way in agriculture to restore imbalanced intestinal microbiota. Recent research shows that intestinal microbiota resist all new-coming bacteria and remove them from the intestinal environment. The initial inoculum at the time of birth shap ....Improving poultry health and performance through microbiota manipulations. The project aims to develop methods to modulate microbiota to improve poultry health and productivity and reduce the need for antibiotics. Probiotic administration is currently the only way in agriculture to restore imbalanced intestinal microbiota. Recent research shows that intestinal microbiota resist all new-coming bacteria and remove them from the intestinal environment. The initial inoculum at the time of birth shapes the gut microbiota for life and has the strongest influence on development of the immune system. Accordingly, at-hatch administration of proven beneficial strains to poultry is likely to ensure permanent colonisation with beneficial bacteria. This process would improve both the productivity and health of poultry and other agricultural animals.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.

Identification of at-risk transition cows: Use of exosomal biomarkers. This project aims to improve the early diagnosis of cows at risk of infectious disease and debilitating metabolic syndromes. Animal health and longevity are pillars of the dairy industry. The risk of death is up to 6 times greater during the transition from pregnancy to lactation, making this ‘transition period’ the time for detection and intervention. If successful, this project will permit the focus of resources on high ris ....Identification of at-risk transition cows: Use of exosomal biomarkers. This project aims to improve the early diagnosis of cows at risk of infectious disease and debilitating metabolic syndromes. Animal health and longevity are pillars of the dairy industry. The risk of death is up to 6 times greater during the transition from pregnancy to lactation, making this ‘transition period’ the time for detection and intervention. If successful, this project will permit the focus of resources on high risk cows and reduce poor outcomes: lower milk production, involuntary culling and increased cow maintenance costs. Within this overall objective, a cost-effective project design will leverage partner facilities and existing networks to translate findings to farm use, thereby clearly delivering economic value.Read moreRead less
Development and implementation of biodiversity information for sustainable management of South Australian groundwater. Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laborator ....Development and implementation of biodiversity information for sustainable management of South Australian groundwater. Clean potable water is one of the most important resources for human health and a successful economy. Increasingly, subterranean aquifers are used for storage and recovery of water. These aquifers contain dynamic ecosystems, but little is known about species composition or about the importance of the presence of various species for water quality. We will use the latest laboratory techniques and DNA identification methods to provide a template for determining ground water diversity and food web dynamics throughout Australia. This project will lead to a better understanding of how to manage ground water in a sustainable manner.Read moreRead less
Early stress experiences and stress resilience in pigs. Animal stress has substantial implications on animal productivity, health and welfare of farm animals and thus farm profitability. This project aims to examine the stress resilience in pigs. Modern pig farming is a major source of food, providing substantial nutritional, social and economic benefits in Australia and worldwide. Animal welfare is of increasing concern to the public, consumers and pork producers, and stress vulnerability is an ....Early stress experiences and stress resilience in pigs. Animal stress has substantial implications on animal productivity, health and welfare of farm animals and thus farm profitability. This project aims to examine the stress resilience in pigs. Modern pig farming is a major source of food, providing substantial nutritional, social and economic benefits in Australia and worldwide. Animal welfare is of increasing concern to the public, consumers and pork producers, and stress vulnerability is an animal health and production problem in the life of the commercial pig. This project will generate new knowledge on early life management to endow stress resilience in pigs, with expected benefits for animal welfare, farm productivity and profitability.Read moreRead less
Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative ....Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative that could be incorporated into DTA programs if their ecological relevance can be demonstrated. This project will develop and validate a new and internationally significant suite of in vitro bioassays for incorporation into DTA programs, leading to more ethical, cost effective and improved environmental protection.Read moreRead less
Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide ....Targeting TGF-beta proteins to control animal reproduction.

This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide a non-surgical method of contraception in companion/feral species, which should address the large unmet need for fertility control in these animals.

Transforming residues from meat processing into engineered soil amendments. The aim of this project is to transform organic residues from meat processing into agricultural soil amendments that actively improve nutrient retention and reduce nitrous oxide (a potent greenhouse gas) emissions. Current disposal and treatment options for meat processing residues are economically and environmentally unsustainable. In this research, a modified hydrothermal carbonisation process will be developed to tran ....Transforming residues from meat processing into engineered soil amendments. The aim of this project is to transform organic residues from meat processing into agricultural soil amendments that actively improve nutrient retention and reduce nitrous oxide (a potent greenhouse gas) emissions. Current disposal and treatment options for meat processing residues are economically and environmentally unsustainable. In this research, a modified hydrothermal carbonisation process will be developed to transform organic residues into novel hydrochars. The influence of these hydrochars on soil nutrient retention and nitrous oxide production will then be assessed using stable isotope tracing, genetic characterisation, and numerical modeling. The project will reduce the economic and environmental costs of organic waste disposal.Read moreRead less

Progress towards a carbon neutral beef industry typically focusses on nutritional strategies, overlooking potential innovations in farming system configuration. This project aims to develop a framework for the integration of Pongamia into beef production systems, so that not only emissions reductions are maximised, but also to support carbon capture and farm system resilience. This project seeks to determine the impact of Pongamia meal on cattle production efficiency, meat quality and methane emissions. Through quantification of carbon sequestration potential in tree plantations, whole-farm modelling will elucidate production scenarios capable of achieving the reductions needed for a carbon neutral Australian beef industry.Read moreRead less
