The integration of cropping and grazing remains a major management challenge in the Mallee. Technology such as portable fencing systems and virtual fencing potentially offer a solution to improve grazing management in large Mallee paddocks with high soil variability. However, to effectively design and deploy these innovative grazing techniques, the grazing behaviour of livestock in these paddocks needs to be understood and quantified.

• For the first time sheep grazing behaviour in a Mallee paddock was monitored and mapped using GPS tracking collars.
• Sheep grazed the entire stubble paddock as they sought out spilt grain during the summer fallow, but they preferred to graze on sandy soil types first.
• While grazing a vetch pasture in the same paddock, livestock spent 50% of the time grazing only 25% of the paddock and 25% of the paddock was not utilised. (iv) At least $4000 profit was foregone from the paddock through the under-utilisation of the vetch pasture.
• Within-paddock fencing technology in large Mallee paddocks has the potential to capture this potential profit by improving feed utilisation.
