Abstract

In developing countries there are often few data available to analyse livestock production systems. This chapter outlines two steady-state models that were developed for the investigation of current and alternative grassland livestock production systems. The StageONE model was designed to primarily analyse feed supply and demand using data collected in farm surveys. The basic functions in this spreadsheet model are the same as used in other more advanced decision-support systems. This model is designed for manual data entry with access to all calculation stages so that it can also be used for training. The time step is monthly and the model is normally used to estimate the energy balance through a year. The StageTWO model uses the same basic functions but is a linear programming model designed to find optimal solutions for livestock systems within the constraints that apply on typical farms. Both models are parameterised with data, collected or estimated, for grasslands, feed sources, livestock, weather and economics.
