Simulation modeling can be a valuable method for extrapolating experimental findings to different weather or management conditions, and for evaluating changes to management. However, few models are available which are capable of modeling complex sheep management. This study evaluated the use of the AusFarm® decision support tool to model a split-joined system using different ram breeds, against experimental results from 2006 to 2010, where stocking rates, management dates and the proportion joined to each breed differed between years. Simulated ewe live weights followed the pattern observed (root mean square error 13 kg), and it is concluded that AusFarm has the flexibility to model sheep systems which are commonly used commercially, but which could not previously be modeled.
