Animal stress has substantial implications on animal productivity, health and welfare of farm animals and thus farm profitability. This project aims to examine the stress resilience in pigs. Modern pig farming is a major source of food, providing substantial nutritional, social and economic benefits in Australia and worldwide. Animal welfare is of increasing concern to the public, consumers and pork producers, and stress vulnerability is an animal health and production problem in the life of the commercial pig. This project will generate new knowledge on early life management to endow stress resilience in pigs, with expected benefits for animal welfare, farm productivity and profitability.Read moreRead less

Summary
Defining single-strand DNA break repair capacity in oocytes. This project aims to investigate fundamental biological mechanisms required for the production of high-quality oocytes, which fortify female fertility and the propagation of all sexually reproducing species. Exploiting unique mouse models, this study will define the importance of single strand DNA break repair capacity in oocytes for the first time, by outlining the role of single strand DNA repair proteins in maintaining genetic integ ....Defining single-strand DNA break repair capacity in oocytes. This project aims to investigate fundamental biological mechanisms required for the production of high-quality oocytes, which fortify female fertility and the propagation of all sexually reproducing species. Exploiting unique mouse models, this study will define the importance of single strand DNA break repair capacity in oocytes for the first time, by outlining the role of single strand DNA repair proteins in maintaining genetic integrity of gametes throughout their lifespan. In doing so, the intended outcome of this project is to dramatically improve our understanding of quality control in the female germ line. This should provide significant benefits to Australia by positioning it as a world leader in the field of Reproductive Science.Read moreRead less

Mapping a complete visual circuit in zebrafish. Our senses perceive the outside world and permit appropriate behaviours, but the underlying brain circuits are poorly understood. This project will use new technologies to observe all active brain cells in zebrafish during the important behaviour of visual predator avoidance and characterise the underlying circuits comprehensively. This approach's significance is in its breadth, spanning functional imaging, anatomy, computational modelling, and beh ....Mapping a complete visual circuit in zebrafish. Our senses perceive the outside world and permit appropriate behaviours, but the underlying brain circuits are poorly understood. This project will use new technologies to observe all active brain cells in zebrafish during the important behaviour of visual predator avoidance and characterise the underlying circuits comprehensively. This approach's significance is in its breadth, spanning functional imaging, anatomy, computational modelling, and behaviour, with the major outcome of producing the first complete map of a visual behaviour at the level of brain circuits and the individual brain cells composing them. Benefits will include new insights into visual processing and the refinement of new genetic, optical, and informatics approaches.Read moreRead less
Heat regulation by the fibre types in muscle. Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the fibre types that make up skeletal muscles regulate heat generation against other muscle function, to maintain core body temperature and the normal movement and posture of the mammal. Project outcomes include defining, for the first time, how heat generation in the muscles o ....Heat regulation by the fibre types in muscle. Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the fibre types that make up skeletal muscles regulate heat generation against other muscle function, to maintain core body temperature and the normal movement and posture of the mammal. Project outcomes include defining, for the first time, how heat generation in the muscles of the body is regulated. This should provide critical knowledge of mammalian evolution and ways to manipulate metabolism, which may provide ways to assist with achieving a desired meat quality and yield in beef and other commercially important animals.Read moreRead less
