Nutrition in the Gouldian finch - developing an optimal 'life-history diet'. Native Australian birds such as the budgerigar, cockatiel, cockatoo, zebra finch and Gouldian finch dominate the pet trade with tens of millions kept across the world. Currently these birds are fed inadequate diets based on a few generic seeds (of European origin). Our study will investigate the nutritional needs of the Gouldian finch and the nutritional content of native Australian seeds, ultimately designing an optima ....Nutrition in the Gouldian finch - developing an optimal 'life-history diet'. Native Australian birds such as the budgerigar, cockatiel, cockatoo, zebra finch and Gouldian finch dominate the pet trade with tens of millions kept across the world. Currently these birds are fed inadequate diets based on a few generic seeds (of European origin). Our study will investigate the nutritional needs of the Gouldian finch and the nutritional content of native Australian seeds, ultimately designing an optimal diet that will dramatically improve the health of these captive birds. We will develop a new product based on Australian plants, which are adapted to growing in even in the poorest soils and climates in Australia and which will form the basis of a new commercial crop for domestic and international markets.

Novel, Cost-Effective Methods for Measuring Methane Emissions from Grazing Livestock. Agriculture is second only to energy generation as a source of greenhouse gas emissions in Australia. Methane from cattle and sheep constitute 60% of these agricultural emissions. Their abatement is a win-win goal for the agricultural industry, reducing greenhouse emissions while increasing food efficiency. This project will develop a novel, cost- and-labour efficient method for on-farm measurements of the emis ....Novel, Cost-Effective Methods for Measuring Methane Emissions from Grazing Livestock. Agriculture is second only to energy generation as a source of greenhouse gas emissions in Australia. Methane from cattle and sheep constitute 60% of these agricultural emissions. Their abatement is a win-win goal for the agricultural industry, reducing greenhouse emissions while increasing food efficiency. This project will develop a novel, cost- and-labour efficient method for on-farm measurements of the emissions of methane from free-grazing cattle and sheep in their undisturbed environment. The method will be used to assess the dependence of methane emissions on factors such as diet and the efficacy of proposed methods for abatement of methane emissions, as well as providing improved data to the National Greenhouse Gas Inventory.Read moreRead less

Digestive Physiology of Crocodilians: Towards an Improved Diet and Feeding Regime for Use by the Farming Industry. 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.

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

Marine fisheries cannot expand further, leaving aquaculture (fish farming) with the challenge of meeting the growing demand for fish, whose consumption is known to enhance human health. Fish oil is an essential component of the feed used in aquaculture, but there is a decreasing global supply of this commodity. This innovative nutritional biochemistry project boosts the capacity of fish to produce their own fish oil from vegetable oils in their diet. Therefore, this project will enable the expansion of aquaculture as an economically and environmentally sustainable means to produce the highest quality, nourishing fish for human consumption.Read moreRead less
Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed.

Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinary project aims to reduce the dependence on fish oils through investigation of basic fatty acid metabolism and endocrinology on farmed fish to ensure that human health promoting characteristics in the final product are retained.Read moreRead less

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
