The WA Department of Agriculture has developed and published an on-line flock structure tool. It is accessible on-line and free of charge. The sheep flock structure tool allows producers to model the impact of changing their flock structure. If you are considering making changes to your flock structure this tool allows you to assess the long term impacts and model different scenarios.
Selling or changing breeding numbers can have a profound impact on the on-going structure of the flock. It is important to determine the changes to the flock over many years to understand the impact of those decisions. The sheep flock structure tool allows producers to model the impact of retaining more wethers, increasing marking rates, selling maiden ewes or retaining ewes for longer.
