Commercial feed blending is a complex process consisting of many potential raw ingredients and final products. The sheer number of daily orders and final products at a typical feed mill means that raw ingredients cannot be mixed to directly produce final products in an economical fashion. As a...

Previous bioeconomic studies have mainly concentrated on beef operations, principally stocker activities, and rangeland conditions. These studies have assumed that the rancher determines some desired weight gain per head over a period, usually one year, and this weight gain is achieved by...

A set of simulations were run to estimate the impact on gross margins due to improvements in cattle breeding efficiency and other management factors in extensive pastoral systems in Western Australia. The output from the simulations was integrated into a statistical model of gross margin as a...

Seven different remaining value functions for tractors and harvesters were estimated using data from advertised prices for used farm equipment. The generalised Box-Cox model was used to nest six of the seven functions. The more complex Box- Cox function explained the data better, but simpler...

Using stochastic frontier analysis, efficiency of production of wheat in Western Australia was studied. The production function model used was a relatively simple input model, consisting of wheat yield, effective rainfall, fertilizer application rates and year of study. Inefficiency was captured...

Although Australia is the sixth largest producer of beef, with production of 2 million metric tonnes, behind regions such as the USA, Brazil and the EU it is the second largest exporter of beef behind Brazil. Average beef exports from Australia are approximately 65% of the total amount of beef...

Deregulation of the Australian dairy industry could effect the utilization of resources by milk producers. In this study we examine the feed input mix dairy producers use, both pastures and supplements, prior to and after deregulation. We are particularly interested in the interaction of pasture...
