Issues and advances in the integrated control of sheep lice.

Ongoing pressure to minimise costs of production, growing markets for low residue and organic wool and meat, resistance to chemicals in louse populations, and the deregistration of diazinon for dipping and jetting have contributed to a move away from routine annual application of lousicides to more integrated approaches to controlling lice. Advances including improved methods for monitoring and detection of lice, an expanded range of louse control products and the availability of a web-accessible suite of decision support tools for wool growers (LiceBossTM) will aid this transition. Possibilities for the future include an on-farm detection test and non-chemical control methods. The design and extension of well-constructed resistance management programs to preserve the effectiveness of recently available new product groups should be a priority.

The performance of broilers offered sorghum - compared to wheat-based diets: a large sacle experiment.

Sufficient evidence tended to indicate that at least four factors can negatively influence broiler performance when offered sorghum-based diets; in particular energy utilisation of sorghum in young birds. It was proposed that mainly CT would further influence sorghum grain AME values when consumed by young chicks (0-7 and 7-14 d old). Overall, birds consuming sorghum-based diets during the starter phase (0-21 d), did not match the performance of birds offered wheat-based diets. The use of phytase enzymes in sorghum-based diets tended to improve bird performance. However, reducing the obtained AME of sorghum grains by -0.8 MJ during the 0-21 d period appears to be a practical solution.

Weaning management of beef calves - practical guidelines for northern Australian

The ‘Weaning management of beef calves – practical guidelines for northern Australian beef producers‘ book or simply ‘the weaner book’ is a compilation of all the research, demonstration and practical knowledge available on weaning and weaner management in northern Australia. Most of this information has been available for some years, but it has not been collated in a single document that is practical and easy to understand. It has been difficult for property owners, managers and their staff to access. The end result of this project is an easy to read guide that has all the available information in one publication. Compiling this information has also highlighted areas where information is limited or non existent or where available information is not being implemented across the whole industry. This has been evaluated and included in recommendations for further research and or demonstration work.

Cost effective formulation of vegetable-protein based diets

The project will provide information on the use of phytase in sorghum based diets so that producers and nutrionists will have confidence in vegetable protein based diets.

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.

Developing improved grazing and related practices to assist beef producters

This project will identify and evaluate grazing management and related practices for beef enterprises in northern Australia that will assist them to build resilience and adapt to a changing and more variable climate. With input from scientists and experienced producers, the trade-offs or synergies between production, sustainability and profitability indicators associated with different management practices will be evaluated in the target regions, using a bio-economic modelling framework. The latter will account for region-specific, climate-change outlooks.
