MIDAS Insights on profitably utilising Perennial Plants on the South Coast of WA. Report to Future Farming Industries CRC

MIDAS is a computer model used to assess the impact of change in a farming system. It describes the biological relationships of a representative farm. This information is used to estimate the profitability of particular enterprises or management strategies. The role of the farm modelling component in this project was to:
1. Quantify some principles about feed supply and demand in grazing systems and enhance understanding of the economics of systems that include perennials. The principles that have been quantified are the:

  •  value of energy at different times of the year
  • sensitivity of the system to altering the pasture supply
  • size of the niche that perennials are filling

2. Quantify the economic value of varying some parameters of different animal production systems (eg time of lambing, frequency of lambing, genotype)
