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.

Development of cattle production extension materials for use in destination mark

To collate support and extension materials to ensure the recipients of Australian cattle have, at least, a minimum understanding of animal husbandry. As the number of destination markets increases, the need will also increase to produce similar material relevant and locally sensitive for these new markets.

Characterising population structure and diversity of Australian Eimeria

Develop microsatellite markers to distinguish strains of Eimeria acervulina, E. brunetti and E. maxima. Conduct nationwide sampling of chicken faeces to build baseline of Eimeria population genetic diversity for 5 economically important speces (3 species above plus E. tenella and E. necatrix). Conduct focused local screening to assess temporal changes in populations historically sampled.

Optimise efficacy of broiler house treatments for the management of lesser mealworm

The Australian chicken meat industry requires effective agents for the management of lesser mealworm in broiler houses. The only two appropriate insecticides currently registered are cyfluthrin and spinosad, with gamma cyhalothrin being developed for registration. The industry requires the efficacy of cyfluthrin to be investigated, with progress and adoption of the latter two chemicals. Optimising the efficacy of each chemical and studying them singly and in rotation will, in addition to improving their efficacy, reduce overall insecticide use and improve their cost effectiveness.

Validation and development of PigBal model - Stage 2

The proposed project involves validate and upgrading the PigBal model to improve the accuracy of manure and GHG production predictions.

DEEDI Paddock Modelling Program

The project objective is to undertake paddock modelling across the Great Barrier Reef catchments to determine magnitude of sediment and particulate nutrient reductions from agricultural lands to GBR lagoon achieved over 5 years. Discussions, development and design of a plan (including a monitoring, evaluation, reporting and improvement plan) for GRASP paddock modelling will be undertaken to determine changes in water quality as a result of land management practices adopted by pastoralists. Biophysical outputs will be derived from range of land types, starting conditions and grazing management strategies. GRASP derived outputs will then be incorporated into water models to determine sediment and nutrient estimates for the catchments.

Meso-scale movement patterns of native fish

The Murray Darling Basin Commison sought information on the movement patterns of native fish in the Murray Darling River system in Queensland. Information is needed to determine daily movement patterns, movement direction and results of flow event analysis.

Development of a Gulf community based natural resource monitoring program.

Development of a Gulf community based natural resource monitoring program, with sawfish as an initial focus.

Development of sustainable management for Pimelea and pimelea poisoning

Toxic Pimelea species (desert riceflower) are naturally occurring species found throughout beef cattle regions of Queensland, New South Wales, South Australia and the Northern Territory. Three species of Pimelea (simplex, elongata, and trichostachya) are poisonous to livestock and potentially fatal to cattle, with serious economic consequences through the loss of production, stock deaths and the costs of agistment. A better understanding of the ecology of the plant/disease is required to develop best practice to manage Pimelea in cattle-producing areas. Development of a chemical assay for the toxin (simplexin) is a key component of the current research project enabling toxin levels to be related to stage of plant growth, environmental and climatic factors.

Seabed biodiversity mapping of the Tweed-Moreton bioregion

This project will contribute to providing scientifically-based ecological assessments of fisheries stocks and habitats required under the Environmental Protection and Biodiversity Conservation (EPBC) Act 1999.
