Sustaining chicken-meat production with alternative protein sources. This project aims to secure sustainable chicken-meat production by the radical reduction or even elimination of imported soybean meal as the primary protein source in Australian broiler diets by its replacement with feed-grade amino acids and local feedstuffs. This project will expand our comprehension of starch/glucose and protein/amino acid digestive dynamics in poultry diets based on wheat, the primary feed grain in Australi ....Sustaining chicken-meat production with alternative protein sources. This project aims to secure sustainable chicken-meat production by the radical reduction or even elimination of imported soybean meal as the primary protein source in Australian broiler diets by its replacement with feed-grade amino acids and local feedstuffs. This project will expand our comprehension of starch/glucose and protein/amino acid digestive dynamics in poultry diets based on wheat, the primary feed grain in Australia; however, wheat does inherently possess nutritional disadvantages. Expected outcomes include soybean meal-free feed formulations for the Australian chicken-meat industry to enhance the affordable and environmentally viable production of chicken-meat coupled with improved bird welfare and flock health.

Summary
Mechanisms of immune protection for infectious laryngotracheitis virus. This project aims to investigate the mechanisms of immune protection against infectious laryngotracheitis virus. This will be achieved by investigating the role of local and systemic immunity and the immune cells associated with long-term protection against disease. The mechanisms of protection against this virus remain unknown which impairs the development of efficacious vaccines. Expected outcomes of this project are a mor ....Mechanisms of immune protection for infectious laryngotracheitis virus. This project aims to investigate the mechanisms of immune protection against infectious laryngotracheitis virus. This will be achieved by investigating the role of local and systemic immunity and the immune cells associated with long-term protection against disease. The mechanisms of protection against this virus remain unknown which impairs the development of efficacious vaccines. Expected outcomes of this project are a more rational approach to vaccination resulting in the generation of more effective and safer vaccination strategies that should benefit our important poultry industry. Additionally, the new methodologies and knowledge on mucosal immune markers could be utilised for the study of other pathogens.Read moreRead less

Summary
Enabling a circular economy for poultry via exploration of metabolism. This project aims to address the environmental and economic burden of food waste by enabling its utilisation as a feed for poultry. This project expects to generate new knowledge in poultry nutrition using a holistic approach exploring the nutritional, health, welfare, economic and environmental effects of food waste diets for poultry. The expected outcomes of this project include enabling food waste diets for poultry and a g ....Enabling a circular economy for poultry via exploration of metabolism. This project aims to address the environmental and economic burden of food waste by enabling its utilisation as a feed for poultry. This project expects to generate new knowledge in poultry nutrition using a holistic approach exploring the nutritional, health, welfare, economic and environmental effects of food waste diets for poultry. The expected outcomes of this project include enabling food waste diets for poultry and a greater understanding of basic nutrition including, carbohydrate and fat metabolism. This should provide significant environmental and economic benefits by utilising food waste that would otherwise go to landfill and improving our understanding of poultry nutrition, giving potential economic savings over $500 million.Read moreRead less
Vaccination of poultry infected with multiple Salmonella serovars. Salmonella is a zoonotic, foodborne pathogen found on eggs and poultry meat. It is the second largest cause of human gastrointestinal disease, thus, reduction of Salmonella on poultry farms is paramount to public health. This project aims to evaluate the long-term efficacy of a commercial Salmonella Typhimurium vaccine against multiple serotypes, including the emerging Salmonella Enteritidis. This project will generate new knowle ....Vaccination of poultry infected with multiple Salmonella serovars. Salmonella is a zoonotic, foodborne pathogen found on eggs and poultry meat. It is the second largest cause of human gastrointestinal disease, thus, reduction of Salmonella on poultry farms is paramount to public health. This project aims to evaluate the long-term efficacy of a commercial Salmonella Typhimurium vaccine against multiple serotypes, including the emerging Salmonella Enteritidis. This project will generate new knowledge in avian immunology using an innovative approach to evaluate the host response to multi-serovar infection. Outcomes of this project will future proof the Australian poultry industry against exotic Salmonella serotypes benefitting the industry by significantly reducing risks of future outbreaks and economic loss.Read moreRead less
Reducing the health & economic burden of Campylobacter using a live vaccine. The aim of the project is to develop a vaccine to reduce Campylobacter bacteria in chickens. Campylobacters cause disease in both poultry and humans. Poultry products are the most common source of human infections. By reducing Campylobacter in poultry, the transfer to humans will be reduced. The expected outcomes arising from this work will be a reduction of the economic burden of poultry losses, in an Australian indust ....Reducing the health & economic burden of Campylobacter using a live vaccine. The aim of the project is to develop a vaccine to reduce Campylobacter bacteria in chickens. Campylobacters cause disease in both poultry and humans. Poultry products are the most common source of human infections. By reducing Campylobacter in poultry, the transfer to humans will be reduced. The expected outcomes arising from this work will be a reduction of the economic burden of poultry losses, in an Australian industry valued at $2.8 billion/year, and an improvement in food safety, thus helping to reduce the burden of foodborne illness, estimated to be $1.2 billion dollars/year. This project is, therefore, poised to benefit the Australian economy, specifically primary producers and the general public, by targeted vaccination of poultry.Read moreRead less
Imperfect vaccination drives herpesvirus evolution through recombination. Vaccines are used to help control disease caused by herpesviruses in animals, but some vaccination programs may drive the evolution and spread of herpesviruses with increased fitness (transmissibility, replication and virulence) through recombination. This project aims to study an important avian herpesvirus (infectious laryngotracheitis virus) in the natural host (poultry) to gain fundamental knowledge of how vaccination ....Imperfect vaccination drives herpesvirus evolution through recombination. Vaccines are used to help control disease caused by herpesviruses in animals, but some vaccination programs may drive the evolution and spread of herpesviruses with increased fitness (transmissibility, replication and virulence) through recombination. This project aims to study an important avian herpesvirus (infectious laryngotracheitis virus) in the natural host (poultry) to gain fundamental knowledge of how vaccination programs influence the emergence of diverse recombinant viruses, and identify which types of vaccination programs are best at preventing the emergence of fitter and more virulent viruses. The results are expected to inform vaccination practices to allow more effective control of these viruses in poultry and other animals.Read moreRead less
