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 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.

Securing future supplies of chicken-meat protein. This project aims to generate advanced knowledge in amino acid metabolism in poultry in order to reduce soybean inclusion in broiler diets. Chicken-meat is the dominant animal protein source in human diets in Australia. However, Australia chicken-meat industry will need to increase production by more than 40 per cent to meet population growth by 2050.

This project aims to generate advanced knowledge in amino acid metabolism in poultry in order to reduce soybean inclusion in broiler diets. Chicken-meat is the dominant animal protein source in human diets in Australia. However, Australia chicken-meat industry will need to increase production by more than 40 per cent to meet population growth by 2050. Soybean meal is the major protein source in poultry diets but the sustainability of increased soy production is problematic. The expected outcomes of this project will be an increase in our future capacity to produce affordable, healthy chicken-meat with humane animal welfare by novel dietary formulations. Chicken-meat production generates less greenhouse gases than its competitors but this project will contribute to the reduction of harmful environmental outputs and ensure food security for Australia.Read moreRead less

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
Manipulation of the growth potential and carcass composition of domestic animal species. Finding alternatives to repeated growth hormone(GH) injection to boost production efficiency and minimise carcass fatness remains an important target for animal research. This application exploits the two novel approaches to achieve this goal through: 1. the administration of the GH releasing peptides to the neonate to imprint an enhanced GH secretory pattern and feed conversion efficiency during growth ....Manipulation of the growth potential and carcass composition of domestic animal species. Finding alternatives to repeated growth hormone(GH) injection to boost production efficiency and minimise carcass fatness remains an important target for animal research. This application exploits the two novel approaches to achieve this goal through: 1. the administration of the GH releasing peptides to the neonate to imprint an enhanced GH secretory pattern and feed conversion efficiency during growth to maturity and 2. the development of an orally active form of these peptides by conjugation with VitB12 to facilitate intestinal absorption through the VitB12 transport mechanism for delivery to the hypothalamic/pituitary axis of animals nearing maturity.Read moreRead less

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.

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

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

The aim of this project is to develop vaccines for the control of swine dysentery (pigs) and intestinal spirochaetosis (pigs and chickens). These infections cause important production-limiting diseases for which no effective vaccines are available. We will use whole genomic sequencing of the two causal species of intestinal spirochaetal bacteria, with a bioinformatics-based analysis of the data to identify potential cell surface structures that will be tested as the basis of new recombinant vaccines. Outcomes will include the development of new commercial products, increased institutional capacity in veterinary vaccine discovery, and ultimately improved animal health and production in rural Australia.Read moreRead less

It builds on work that has demonstrated the efficacy of an experimental vaccine. The proven antigen, NetB, will be expressed in live delivery vehicles, including the apicomplexan parasite Eimeria and several bacteria strains particularly suited to use in chickens. Comparative analysis of the different vaccine vehicles will allow evaluation of the relative advantages and disadvantage of the different vehicles for delivery of heterologous vaccine antigens, thus informing the choice of appropriate vectors for this and other vaccine applications.Read moreRead less
