A GOAT population modelling project is already yielding results for New South Wales producers.
In Meat & Livestock Australia’s Market News section, goat industry development manager, Julie Petty, said a critical requirement for a viable, long-term goat industry is accurate and reliable data on supply.
For this reason, MLA and the Goat Industry Council of Australia have funded a population modelling project initiated by the New South Wales Department of Primary Industries.
Existing data from sources such as NLIS Limited, aerial surveys, and FARMS (NSW stock and land return information) is being drawn together to develop population and supply models to support industry forecasts. The models will enable industry to estimate the number of goats managed, unmanaged and marketed annually.

Ms Petty said the project will allow for modelling of population changes and the sustainability of supply under different harvesting rates. In summary, this project seeks to generate reliable information to improve industry’s ability to forecast supply.
Initially, the project has focused on establishing a method for population and supply forecasting within NSW. Once the methodology has been proven, it will be rolled out nationally to other significant goat production areas, Ms Petty said.
Through the project, supply forecasting processes will be established, similar to those used in the sheep and cattle industries. Producer surveys are likely to be undertaken and a forecasting committee established to review forecasts and adjust parameters based on industry knowledge.
Results from the NSW analysis to date have revealed the below (Table 1) goat population estimates by region. The data is derived from kangaroo and aerial survey counts conducted in the winter of 2016. The regions are the kangaroo management regions in NSW and a map is available to view here. The aerial survey counts do not distinguish between managed and unmanaged goats.

If producers receive a survey from MLA or NSW DPI asking for information about goat numbers, they are asked to complete and return it.
