Development of novel omega-3 enriched poultry products. New Health recommendations and changes to the Food Standards Code encourage greater dietary intake of omega-3 (w-3) fatty acids. Our core research on modifying fatty acid composition of poultry tissues and preliminary studies with our industry partner's proprietary fishmeal product (PorcOmega) have indicated the feasibility of producing novel meat products and eggs with high w-3 contents, which would qualify to carry a new nutrition label. ....Development of novel omega-3 enriched poultry products. New Health recommendations and changes to the Food Standards Code encourage greater dietary intake of omega-3 (w-3) fatty acids. Our core research on modifying fatty acid composition of poultry tissues and preliminary studies with our industry partner's proprietary fishmeal product (PorcOmega) have indicated the feasibility of producing novel meat products and eggs with high w-3 contents, which would qualify to carry a new nutrition label. We now propose, in collaboration with our industry partner, to assess the viability of producing such products by conducting poultry feeding trials with PorcOmega on a commercial scale and evaluating both the levels of w-3 enrichement of chicken breast, thigh and sausages, shelf-life and consumer acceptability (sensory evaluation) of these products. We expect to establish feeding strategies for adoption by commercial producers of premium poultry and eggs for local or export markets.Read moreRead less
Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding p ....Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding protocols for meat production in agriculture and identify targets for risk management and for preventing and ameliorating early life overfeeding effects in humans. This investigation therefore has clear benefits to the social, economic, and health aspects of obesity and to basic science and agriculture.Read moreRead less

Optimising the Strategy for Breeding Micronutrient-Dense Staple Foods that Improve Human health and Nutrition. The project is part of a new paradigm for agriculture in which staple crops are bred with greater micronutrient density to improve human health. It generates strategic basic information on how nutrients interact in the body of animal models in absorption, transport and utilisation that will allow plant breeders to optimise the breeding strategy for maximum outcomes in health and minimum ....Optimising the Strategy for Breeding Micronutrient-Dense Staple Foods that Improve Human health and Nutrition. The project is part of a new paradigm for agriculture in which staple crops are bred with greater micronutrient density to improve human health. It generates strategic basic information on how nutrients interact in the body of animal models in absorption, transport and utilisation that will allow plant breeders to optimise the breeding strategy for maximum outcomes in health and minimum breeding cost. Animals deficient in the nutrients of most concern (iron, zinc, vitamin A - and inulin) will be fed new varieties with enhanced levels of these factors, and from the responses, a superior strategy will be developed.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
New Approaches to the Control of Post-Weaning Diarrhoea in Piglets. In Australia, post?weaning diarrhoea (PWD) in piglets is a major constraint to efficient and profitable production. Increasing levels of resistance to dietary antibiotics by gut pathogens such as Escherichia coli, the bacterium implicated in PWD, is a major reason for this problem. This research will identify nutritional means of controlling PWD and increasing production after weaning. This will be achieved by strategic nutritio ....New Approaches to the Control of Post-Weaning Diarrhoea in Piglets. In Australia, post?weaning diarrhoea (PWD) in piglets is a major constraint to efficient and profitable production. Increasing levels of resistance to dietary antibiotics by gut pathogens such as Escherichia coli, the bacterium implicated in PWD, is a major reason for this problem. This research will identify nutritional means of controlling PWD and increasing production after weaning. This will be achieved by strategic nutritional interventions in the pre-weaning and (or) post-weaning periods targeted at reducing bacterial pathogens in the gut. A reduction in PWD will increase the overall efficiency of pig production in Australia and reduce antibiotic use.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
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. This international, comparative and multidisciplinar ....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. 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
