There is a need for egg businesses to demonstrate good environmental performance and stewardship as changes to environmental regulation adds uncertainty to industry investment decisions.
Investing in R&D that provides a single source of information to assist industry and regulators in the development process will reduce the time and cost of developing new facilities and/or expanding existing facilities. Furthermore, it will enable industry to maintain high levels of environmental management.
Reducing ammonia losses during composting of chicken manure without altering economic outcomes
This research trialled mixing poultry manure with organic materials such as sawdust and wood chips, in an effort to produce a nitrogen rich compost product.
Addition of sawdust or wood chips to manure was shown to maximise nitrogen retention but at an increased compost production cost.
Egg Industry Environmental Guidelines
This project aimed to deliver improved environmental sustainability and planning outcomes for the egg industry by updating the existing guidelines to reflect changes in the industry since its first publication in 2008.
Odour Review of Layer Farms and Development of S-Factor Formula
This project was conducted to develop an S-factor formula to be integrated into the revision of the Environmental Guidelines for the Egg Industry. A robust and science-based separation distance (S-factor) formula will provide improved planning and development outcomes for the egg industry and will provide greater certainty that community amenity impacts can be managed for new and expanding layer farms.
Evaluation of Energy Usage and Ventilation Performance of Tunnel Ventilated Layer Sheds
Due to increasing pressures on operating margins within the Australian egg industry, this study investigated the energy usage and ventilation systems in cage egg sheds.Optimising electricity usage is an important factor in improving the bottom line of egg production systems.
Environmental Assessment of an Egg Production Supply Chain using Life Cycle Assessment
A Life Cycle Assessment model was used to provide a review of the efficiency of Australian egg production with respect to greenhouse gas emissions, water use and energy use.
Layer Hen Manure Analysis Report
Poultry layer manure and litter composition data are essential for accurately determining sustainable application rates of manure to crops and pastures.This study collected some 20 samples of manure and litter from five different layer production systems from all major production regions in Australia.
Composting Every Day Mortalities and Other Wastes from Layer Farms
Composting is a viable alternative method for disposing of daily mortalities, spent hens, egg and other waste produced on Australian egg farms.
Reducing disease spread and neighbour complaints by integrated fly control on egg farms
Due to the number of issues caused by fly populations in relation to the Australian agricultural industry, this project seeks to provide further information about the dynamics of flies breeding on Australian egg farms.
Urban Fringe Land Use Conflict: Two Poultry Case Studies
Land use is a common source of conflict for many sectors of Australian agriculture including the poultry industry, particularly in areas on the urban fringe or where there is significant rural residential development.
