Economic effects of alternate growth path, time of calving and breed type combinations across southern Australian beef cattle environments: industry-wide effects

摘要

The ‘Regional Combinations’ project and its biophysical outcomes, and the subsequent identification ofnthe most profitable beef cattle production systems across different environments in southern Australia, have beenndescribed in several other papers in this special edition. In this paper, the economic calculations reported for each ofnthe individual beef enterprises representative of the various state sites are aggregated up to the level of the Australianncattle and beef industry and then projected forward over several years into the future. To do this, an existing model ofnthe world beef market is used. The analyses suggest that both the fast-growth-rate technology and the time-of-calvingntechnology have the potential to generate significant economic benefits for the southern Australia cattle and beefnindustries. The cumulative present values of each technology are around $70 million over a 15-year time horizon at an7% real discount rate
