An economic model was developed to compare two different farm systems using the production results and reproductive performance figures derived from an observational study of 14 seasonally calving dairy herds in Victoria. The farm systems modelled were a crossbred herd comprising Jersey x Holstein-Friesian and Holstein-Friesian x (Jersey x Holstein-Friesian) breed types and a herd of Holstein-Friesian cows with farm operating profit as the outcome.
