Sustainable beef production from irrigated fodder in the Pilbara
There are changes occurring in the north that have the potential to dramatically change the production efficiency and sustainability of cattle in the north and the livelihoods of the pastoralists and indigenous communities in that area.
The main changes that have occurred are the use of groundwater and mine dewatering to produce fodder under pivots, the increased interest in pastoral cattle moving to backgrounding properties in the south, novel methods of managing grazing pressure and an interest in diversifying markets for northern WA beef cattle.
This project focusses on the gap in knowledge that exists about what to grow under the pivots, how to use it most effectively and how to integrate it with the rangeland feedbase to maximise production efficiency and improve the health of the rangelands and reduce the environmental footprint of the industry.
One of the major challenges normally facing pastoralists is uncertainty around rainfall leading to uncertainty about the type, amount and quality of feed and ultimately the consistency of the supply of animals of the right specifications through the supply chain. If we can develop new systems that make optimal use of the fodder generated under pivots we have an opportunity to provide more certainty and interest from emerging markets.
- The overall goal of the project is to determine if pivot irrigation systems can be developed to create a cost effective and more reliable improvement to current supply chains
- Another main goal is to determine what’s best to grow under irrigation and how best to use it in combination with the rangelands to maximise productivity and minimise the environmental footprint of the new systems.
I am an animal scientist who is driven by the need for ‘Clean, Green and Ethical’ production systems and an interest the role of our native Australian plants in grazing systems; I am in the School of Agriculture and Environment at UWA. The main focus of my work is around the interaction between plant secondary compounds and the ruminal microbial community in improving production efficiency and reducing methane emissions. My current interest is in the mosaic feedbase in the northern WA rangelands and the most effective way to manage cattle transitioning across different parts of the mosaic including the production of forage under pivot irrigation, which is a recent development in northern WA. Optimising the transition of animals across the feedbase mosaic and making use of the rich diversity of plant secondary compounds in the native rangelands plants will be essential for improving the resilience of the supply chain and move towards more carbon neutral systems.
