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
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
Enhancing aquaculture production of the tropical abalone using complementary genetic and environmental approaches. While temperate abalone are one of our most valuable seafoods, there is a growing demand worldwide for the ?cocktail?-sized tropical abalone Haliotis asinina. Australia is well positioned to capture the market for this rapidly growing species. We propose to enhance the already favourable growth rates of Haliotis asinina in aquaculture by delineating critical environmental and geneti ....Enhancing aquaculture production of the tropical abalone using complementary genetic and environmental approaches. While temperate abalone are one of our most valuable seafoods, there is a growing demand worldwide for the ?cocktail?-sized tropical abalone Haliotis asinina. Australia is well positioned to capture the market for this rapidly growing species. We propose to enhance the already favourable growth rates of Haliotis asinina in aquaculture by delineating critical environmental and genetic factors that effect production. This proposal uniquely melds commercial production practices at MG Kailis Export Pty Ltd with expertise in aquaculture and marine biotechnology present at The University of Queensland and CSIRO Marine Research. This knowledge will enhance the development of this new aquaculture industry in tropical Australia.Read moreRead less

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 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

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

Crocodile farming promotes the sustainable production and consumption of crocodile products without harming natural populations. The industry grosses over $15 million per year in Australia and $200 million worldwide. Costs associated with transporting and storing food are the single largest expense that crocodile farms have. Increases in the efficiency of converting food into growth will have positive economic benefits to the industry. Efficiencies can be produced by (1) increasing food absorption, (2) decreasing the energetic costs of digestion, and (3) producing a new food that is less expensive to ship and store. This project will directly address the first two of these and will lay the foundation for the development of the third. Read moreRead less
