Livestock farming in the Northern Tablelands of NSW is a big deal, with sheep and cattle being the main focus. A study created a model to understand the economic aspects of these farming systems. They looked at the costs and income involved in running a farm, including assets like land and livestock. The model showed that the farm made money from selling livestock but also had costs like feeding and maintaining the animals. The researchers used data and simulations to create this model, which can help farmers make decisions about their operations.
