A simulation and economic model of a whole-farm sheep enterprise is used to investigate the individual genetic, nutrition and maternal efficiency factors on profitability, labour use and groundcover. There were no differences in efficiency or profitability between large or small sheep when appropriate stocking rates and lamb slaughter weights were applied. Mating ewe lambs improved profitability in all scenarios, while modifying the growth curve realised only small improvements. Recommendations on genetic selection and farm management in the sheep industry should consider whole-farm and non-economic factors such as groundcover and labour, which are implicated in the selection of profitable farm systems.
