Development of a new diet to improve insulin sensitivity and manage weight in healthy cats. This project will determine if a low carbohydrate, moderate fat, high protein diet improves insulin sensitivity and reduces weight gain in cats compared to a typical high-carbohydrate grocery line diet. It will identify risk factors for weight gain such as increased fasting insulin concentration and will also determine which simple assessment of insulin sensitivity best correlates with insulin sensitivity ....Development of a new diet to improve insulin sensitivity and manage weight in healthy cats. This project will determine if a low carbohydrate, moderate fat, high protein diet improves insulin sensitivity and reduces weight gain in cats compared to a typical high-carbohydrate grocery line diet. It will identify risk factors for weight gain such as increased fasting insulin concentration and will also determine which simple assessment of insulin sensitivity best correlates with insulin sensitivity measured by a gold standard. This project should lead to the formulation of a diet designed to improve insulin sensitivity and minimize weight gain in cats, and allow for earlier identification of cats at risk of obesity.Read moreRead less
Early life nutrition to improve feed efficiency in commercial dairy goats. 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 improv ....Early life nutrition to improve feed efficiency in commercial dairy goats. 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
How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of natu ....How to make antibiotics in pig feed redundant, naturally. Antimicrobial resistance has become a major issue in human and veterinary medicine being partially caused by the use of in-feed antimicrobials in farm animals. This project aims to completely eliminate antimicrobials from piglet feeds. The key differential approach is based on helping the physiology of the animal rather than testing interventions against bacteria. The project will consist of developing a novel nutritional strategy of naturally (through maternal conditioning) boosting the natural appetite and the capacity to digest in piglets early in life. The anticipated outcome is that the new peri-natal program will result in minimal bacterial proliferation and diarrhoea thus, negating the need for in-feed antimicrobials in piglets.

Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide ....Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide a non-surgical method of contraception in companion/feral species, which should address the large unmet need for fertility control in these animals.

Mechanisms of manchette function. This project aims to define the function of the manchette, a poorly understood microtubule-based structure present in haploid male germ cells. This project aims to define key mechanisms underpinning manchette development and movement, and to generate a detailed picture of the dynamics of germ cell development using imaging technologies and unique animal models. Such knowledge should improve the understanding of how male fertility is achieved, the origin of infer ....Mechanisms of manchette function. This project aims to define the function of the manchette, a poorly understood microtubule-based structure present in haploid male germ cells. This project aims to define key mechanisms underpinning manchette development and movement, and to generate a detailed picture of the dynamics of germ cell development using imaging technologies and unique animal models. Such knowledge should improve the understanding of how male fertility is achieved, the origin of infertility and how species-specific differences in sperm form are achieved. Such insights may ultimately lead to improved agricultural efficiencies and job creation.Read moreRead less

This proposal aims to use an innovative approach to address an urgent issue raised by the end users of an Australian-owned poultry vaccine with an extensive global market. Recently multiple mutations have been detected in the vaccine re-isolated from vaccinated birds in the field around the world. We will apply a combination of a novel technique for targeted mutagenesis, genome sequencing, and animal experimentations, to address the significance of these mutations. Results will improve our understanding of the basis of attenuation of the vaccine, its mechanism of action, and provide commercial confidence in the safety of the vaccine, which is needed to support Australian Universities and Businesses, and the global poultry industry.Read moreRead less
Maximizing male fertility: the role of CRISP proteins. This project aims to investigate the function of cysteine rich secretory protein (CRISP) family members in fertility. It is expected to generate new knowledge on the role CRISP1 and 4 play in sperm competition in vivo, and thus, evolutionary processes; to define the role seminal plasma CRISPs play in fertility; and identify the mechanism underpinning their biological activities. This will be achieved using a range of innovative, state-of-the ....Maximizing male fertility: the role of CRISP proteins.

The routes of infection with sheep scrapie and agents that cause related prion diseases. We will define the routes by which the infective agents for scrapie, a debilitating disease of sheep, reach the nervous system after being consumed with food. Scrapie is from the same disease group (prion diseases) as mad cow disease. There would be a large economic cost were prion diseases to infect agricultural animals in Australia, through bioterrorism or accident. An outbreak in sheep could ruin the indu ....The routes of infection with sheep scrapie and agents that cause related prion diseases. We will define the routes by which the infective agents for scrapie, a debilitating disease of sheep, reach the nervous system after being consumed with food. Scrapie is from the same disease group (prion diseases) as mad cow disease. There would be a large economic cost were prion diseases to infect agricultural animals in Australia, through bioterrorism or accident. An outbreak in sheep could ruin the industry, as our export markets would be immediately blocked, and thousands of animals would be killed to stop disease spread. The benefit of clearly understanding how the infective agents reach the nervous system is that this may lead to strategies to intervene, and thus limit the spread and seriousness of infection.Read moreRead less

There are an estimated 1.2 million horses in Australia, and the horse industry is estimated to contribute over $6.3 billion to the economy. Laminitis is a significant health and welfare problem in Australia, as it is worldwide, causing pain and lameness, loss of use, and sometimes necessitating euthanasia. Laminitis is one of the most common reasons for horse owners to seek veterinary attention, and diet and obesity increasingly predispose to this condition. Since treatment of laminitis is difficult, prevention is crucial. The outcomes from this project will include the provision of more specific advice on dietary and exercise management to vets and horse owners to reduce the incidence and impact of laminitis on the horse industry.Read moreRead less
