Fish stocking programs - assessing the benefits against long term impacts

This project addresses the R&D priority for an Environmentally Sustainable Queensland through the strategy of developing and implementing ecologically sustainable fishing practices. The principal findings of this research project will be discussed at a national workshop with the twin goals of promoting an understanding of the major elements of sustainable fish stocking practices and discussing and planning the way forward for the implementation of change. The workshop participants will include fisheries managers, representatives from interested community groups and other stakeholders.

CBRC Jungle Perch Research

Part of CBRC funding "Living the Queensland LIfestyle" initiative. For the purpose of delivering fisheries research on the jungle perch species to restore recreational fishing stocks in south east Queensland and central Queensland.

Northern Grazing Systems Project Development

Control of grazing distribution, management of stocking rate, wet season spelling and fire

Improving efficiency of pig feed manufacturing and application of additives

Improving the efficiency of pig feed manufacturing and application of additives.

Increasing seedstock production of domesticated giant tiger prawns

DEEDI has been approached to perform an important outdoor pond experiment using the heated nursery ponds at Bribie Island Aquaculture Research Centre to get tiger prawn broodstock out of expensive clear-water tank systems and into ponds. This approach will enable a faster and more cost-effective adoption of existing selective breeding technology. Additional benefits will involve increased profitability and sustainability of genetic selection programs, improved understanding of prawn maturation benefiting other tiger prawn research and improved collaboration between DEEDI and CSIRO.

Quantifying greenhouse gas emissions from Australian piggeries

Current research proposal will conduct a review of measurement techniques and recommendation for a suite of techniques to be used in method and measurement protocol development.

Antibiotic Sensitivity Testing

Respiratory bacterial pathogens in pigs are currently treated with antibiotics. Intervet - Schering Plough markets an antibiotic called Nurflor (Florfenicol) targeting respiratory pathogens. This project tests the effectiveness of this antibiotic against a series of respiratory pathogens. 6 isolates will be tested per serovar/strain and the isolates will be from 4 different farms using MIC testing. The sensitivity of Florfenicol will be compared to sensitivity of the organisms to Tilmicosin and Amoxicillin. Development of resistance to certain antibiotics have been reported, so it is important to have alternative antibiotics available to treat the respiratory pathogens on farms.

The Keys to Healthy Savanna Lands

This project will refine the Savanna Plan program to better promote sustainable grazing practices across the northern rangelands, further engage the beef industry and investigate and develop Savanna Plan's potential to provide practical tools for carbon sequestration on pastoral properties across northern Australia.

Haemophilus parasuis treatment

The aim of the project is to prove that live vaccination on the farm will protect the piglets from heterologous challenge with H. parasuis. The steps to achieve the aim of the project are to find a dose rate on the farm which guarantees colonisation of the vaccine strain and is safe On farm vaccinated and unvaccinated pigs are then shifted to CAAS at three weeks of age and challenged with a heterologous strains. The method is then applied on a large piggery for a period of nearly 12 months. We will also develop a freeze drying method and a technical manual of procedures to identify serovars prevailing on pig farms and which serovar to include into the vaccine.

Lot feeding and intensive livestock manure and effluent management

Manure management emissions may present much greater opportunity for greenhouse gas mitigation in the feedlot, pig, chicken meat, egg and diary industries, than the current IPCC and DCC calculation guidelines suggest. Current literature and understanding of manure mass loss throughout the manure management system does not support these current guidelines; in which the emission rates are fixed and consequently don't allow incentives for reduced emissions.

Improving the efficiency of pig feed manufacturing and application of additives

This project aims to reduce production costs for high-quality pork through understanding how commercial processing conditions affect mill throughput, processing energy efficiency, product durability and the nutritional value of pig feed.

Management of pain associated with bull castration

There is a need to have infertile male cattle in the Australian beef herd. There is, currently, no non-invasive alternative to the castration of cattle, nor is there likely to be one in the near future. There is ample scientific evidence demonstrating that castration causes stress and pain, and with the community increasingly scrutinising farming practices and seeking assurance that they are humane, there is a clear need to develop practical strategies for minimising the pain and stress associated with castration.

Rapid typing of P multocida

Fowl cholera, caused by P. multocida, is a serious disease of poultry with sudden surges in mortality and an emerging disease of the free ranged poultry industries. This project will develop a more rapid and cost effective screening method for P. multocida. The impacts of this new method are manifold: It will lead to an improved understanding of the epidemiology of fowl cholera and the possible sources of entry onto the farm leading to improved biosecurity measures and control programs. Another impact is improved serotyping, which will ensure more effective and targeted vaccination programs. Improving prevention and control programs and decreasing the reliance on antibiotics will enhance the sustainability and profitability of the industry.

Methanotrophs from natural ecosystems for ruminant methane mitigation

Enteric fermentation of methane by ruminant animals represents a major source of anthropogenic methane production. Methane produced in this manner is released to the atmosphere where it is highly efficient at absorbing thermal radiation, which consequently increases the global surface temperature. Although many different strategies to control ruminant methane emissions have been considered, few are currently considered viable. Obligate and acultative methane oxidising bacteria (MOB) and anaerobic methane oxidising archaea (ANME) play a fundamental role in the carbon cycle by metabolising methane before it is released into the atmosphere. Because of this, methanotrophic microorganisms represent a novel biological control agent in mitigating ruminant methane emissions. This project aims to characterise methanotrophic microorganisms from a range of environments, and to subsequently determine the metabolic activity of these microorganisms under in vitro rumen-like conditions.

Producer Demonstration Sites (PDS) coordination and delivery
