Improved Whole-farm Planning for Mixed-enterprise Systems in Australia using a Four-stage Stochastic Model with Recourse
Young et al
A paper comparing more common deterministic steady state model with stochastic model. Results reveal key differences in farm management and profit when weather variation is considered.
Modelling for Dummies
John & Michael Young

- At the same age which are the higher priority to keep, fat or thin ewes?
- Does it pay to maintain ewes using grain this year?
- For early lambing flocks that will only have dry feed from now till next lambing, will it pay to have ewes in confinement for 12 months?
- Does it pay to put weight on ewes using grain feeding?
- What is the priority for the limited green feed this spring
Economic implications of the loss of glyphosate and paraquat on Australian mixed enterprise farms
This paper looks at the topical issue of the loss of glyphosate and paraquat herbicides in broad acre farming systems. The paper details management changes that would likely be implemented to best adapt to proposed regulations and restrictions. Published article can be found here
The value of sowing cereals into pastures
This article examines the economics of “bulking” (sow cereals into) pastures. The following questions are addressed:
- What is it worth to sow cereals into pastures?
- What seeding rate should I use?
- How many hectares should I sow?
- If I sow cereals into my pasture do I need to alter my livestock management?
- What is the cost – benefit break down of sowing cereals into pastures?
An economic analysis of sheep ﬂock structures for mixed enterprise Australian farm businesses
This analysis thoroughly examines the effect of different sheep flock structures on farm management and profitability in the south-west of the Western Australian Wheatbelt. It includes sensitivity analyse for; price change, sheep management and crop management. Published article can be found here
Effectiveness of a Supply Chain at Out-of-Season Lamb Production
This report evaluates the effectiveness of a supply chain at producing out-of-season heavy export lambs by providing an analysis of feed allocation within the supply chain, a grazing pressure sensitivity and an evaluation into the profitability of chaff piles and crop grazing.
MIDAS Farm Relations Analysis
This report quantifies the farm interactions represented in MIDAS, to help users understand and interpret results. It also provides an understanding of how each aspect of the farm system contributes to farm profit.
